Which one of the three heat transfer processes best describes this action of the blood? While the authors are currently relevant and up to date. I would also recommend reminding readers where the answers to the comprehension questions can be found (i.e. read more. I have not found any errors within the text. (b) What volume would this air occupy at room temperature and 1atm1 \mathrm{~atm}1atm pressure? These details will inevitably be explored more deeply as students progress through their program of study. But I'll need student feedback to assess whether it reads clearly to students. This is inevitable to some extent in any text, but the editors have some smoothing out to do. The organization of the book is intuitive and I can easily find information and readings associated with class topics through the table of contents. Note: I have not yet used this book in a class.

The text could have certainly benefited from using the pictures of scientists to give a human face to the work presented. Graphics I would love to see a version that takes advantage of the electronic format more and becomes a little more interactive. Overall, acceptable trade-off to conventional high quality textbooks. There are roles for deterministic processes and stochastic processes. I didn't notice any content that was culturally insensitive or offensive, but I didn't notice anything particularly inclusive, either. I havent seen anything like this in any other biology textbook. However, I did not encounter anything glaring. Finally, the sections on eukaryotic transcription, translation, and gene regulation (Ch 15 & 16) provide sufficient background for students to understand why all cells in an animal can have all the same genes but nonetheless have very different patterns of gene expression and function. The biggest issue, though, is the images. A chapter summary provides a good review for students, and I sometimes advised students to read the summary first, before getting into the weeds. Students are generally not familiar with archaea and it seems the authors of this textbook share this lack of understanding. This textbook is available in a variety of formats, and each is easy to use. One area that may need updating are topics such as phylogenetics and climate change; however the authors do a good job of giving relative examples. This review will focuses specifically on a representative chapterin this case, Chapter 7: Cellular Respiration. No internal links were dead or misdirected, and figures were clear. For the level of students being targeted, there is sufficient focus. These resources vary in quality, but links do work properly and redirect to functioning sites. In other words, the new content will be a much more manageable 300 pages that will complement short videos I prepare. All topics are covered Complex topics are clearly presented, many terms are defined, and there is a logical progression of ideas and information. This textbook reads much like any other textbook. In many cases, we found this necessitated rereading and trying to interpret meaning from sentence context. Its nice to have a free textbook from a reputable university that can give students from lower incomes the ability to have the same depth and breadth of information for no money on or before the first day. It is a scientific text and presents the material in a way that should not be offensive to any one. Very evident in Cellular respiration chapter I reviewed the book for use in the Chapter 7 was broken down into small, manageable sub-sections which could be easily assigned to students. I found no problems navigating through the pages. read more. Professor, Science Dept. I think this book is comprehensive for a general biology textbook, but it lacks some depth and breath for However, the authors did an excellent job of looking at a global perspective when reviewing conservation issues and biodiversity on other continents. That may be true for most humans, but some humans have 45 or 47. The chapter-end questions, the opening outlines, and other such framing devices are used consistently throughout the book. There are a number of concepts or topics that are very poorly explained. I looked over the major sections that I regularly teach (chapters 1-16) and I didnt run into any inaccurate information. Content-wise, Biology -2e very closely aligns itself with most traditional introductory Biology text books. I believe the time is ripe for a revised edition. The term Agnatha was abandoned long ago, as jawless fishes include cyclostomes and ostracoderms and are not a clade. Overall, modularity is good; however, between chapters (in the PDF versions) there is a blank white page. There are no issues with images or charts. The factual context of the writing made for very quick reading. In other sections, the definition of hypothesis is accurate. Aside from the figures, other aspects of the interface function well. In general, the text is simple to follow but some sentences are awkward to read; there was also unnecessary use of abbreviations that might not make it easier for freshman and sophomores who may want to use the text. There really is nothing this book doesnt provide that I would absolutely need as an instructor to teach my course. That is confusing. The chapter sections are well defined and accurately titled. Comprehensiveness in an introductory biology textbook is a daunting At the level of details, I found a few places in the text in which terms were used before they were defined, though in such cases they were usually defined in the following paragraph/page. One misconception is in the link on text page 149 to the process of diffusion as it actually links to a video showing dispersion of a dye in water due to turbulent currents created by adding the dye to a beaker of water (and is correctly labeled as dispersion in Wikipedia), rather than diffusion. I didn't notice any major errors, but there were some omissions, especially in the evolution section, which is a disaster. Overall, this book provides a mostly adequate resource for teachers who are trying to save on textbook costs. In approximately 280 pages these offer a solid introduction to structure and physiological function. Review Questions at End of Section With failing vision reading from a standard text book requires good lighting and magnification. The chapter summaries and key terms are nice editions for students and illustrations are clear and professional. In Figure 4.6: Relatives sizes on a log scale Students will be confused and uncertain how the two strands are represented. However to meet the learning outcomes for each and individual institution extra supplement must be provided. This statement on page 488 is not necessarily true: A geographically continuous population has a gene pool that is relatively homogeneous. Do you look forward to treating your guests and customers to piping hot cups of coffee? read more. In some cases simplification can result in explanations that lack the accurate nuance of a more complex explanation, but that is a necessary tradeoff in an introductory text. Unit 1: The Chemistry of Life, Unit 2: The Cell, Unit 3: Genetics, etc. Concepts and Connections). The textbook is organized in a clear and logical way. Terminology is consistent in most chapters read. The line width of text on the pdf download was a little wide for easy scanning, I would prefer a two column per page format, but that may simply be personal preference. My impression is that with a publication date of 2013 the book is in need of revision now (2018). I had a few problems with the textbook interface while reading it on Adobe Acrobat reader. Some of the language is loose: "Need for osmoregulation" implies that osmoregulation happens because it needs to happen, instead of correctly stating that "osmoregulation happens" because of all the partnering proteins, the membranes, the solutes, the pumps, etc. The material is presented in a logical and consistent manner to facilitate effective learning and understanding. In some cases, the inconsistencies appear to be associated with oversimplification. This text is modular in the way that most textbooks are modular -- information is organized into chapters, and chapters are organized with subheadings. As I would expect, this chapter is organized in a logical, straightforward manner. I also do not like being required to download some videos through links, but would rather watch the video within the website. Reviewed by Mark Platta, Faculty , Central Lakes College on 1/7/16, Biology was very comprehensive in its covering of general biology topics and the "Link to Learning" feature allows the learner to expand the concept. hypothesis variable theory control 6. They are at just the right level for a first year biology student. Reviewed by Joseph Ly, Lecturer, St. Ambrose University on 10/26/18, Is able to cover aspects of biology very well. I would not suggest adding more subjects and I appreciate the depth of coverage in the text giving the instructor the option to choose which sections to focus on in their courses. Having a downloadable online text allows me and others the ability to adjust light intensity and size easily on the monitor.

Carrying capacity is a feature of a populations environment, not of the population. The content is as accurate as I expect from a biology textbook. However, the image shows the reversesubstrate-level phosphorylation of ATP, in which the third phosphate is attached to ADP from some substrate. This particular information is relatively new in the field of biology, though most of the current discoveries lie in the realm of gene function and would be included in an upper level course. From photosynthesis: cyclic reaction in photosynthesis, CAM and C4 photosynthetic adaptations, Fate of triose-P after Calvin Cycle, Any regulation of photosynthesis Students who did these problems would gain in understanding, but I think the questions are not especially strong with respect to developing new skills at applying the concepts, doing broader analysis, or synthesizing ideas. read more. I know that several other reviewers commented on errors they found in this textbook. Im used to seeing A&P chapters laid out from an evolutionary perspective (e.g. The graphics are fewer and lower quality compared to expensive conventional textbooks, and the study questions are fewer and less thoughtful--an expected and acceptable trade-off given that this book has the potential to save students hundreds of dollars. The Biology 2e text is comprehensive without being overwhelming and provides a similar organization and logical flow as the previous text. Each unit is divided into multiple chapters, which are themselves, subdivided into sections with clear headings. WebBiology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. I would like to see more supplementary materials generated, things like end of chapter problems that are not so dependent on multiple choice. My students have always struggled with the ever-higher page count zoology or integrative biology textbooks. This is not an enlightened book, but I have not found it to lack images and examples from across the spectrum of humanity. For example, Cell Communication, Cell reproduction, Mendelian genetics and non-mendelian traits, DNA replication and repair and mitosis and meiosis I believe are covered adequately. This book is written at a level that is very accessible to my college freshmen and sophomores. The book could definitely be broken up into small sections for lectures, discussions and homework. It covers all the topics in sufficient detail for the student to succeed. Presentation is straightforward, but I find that supplementing with additional web based teaching read more. Since the text is foundational, many of the subjects aren't changing rapidly. Most importantly, they help you churn out several cups of tea, or coffee, just with a few clicks of the button. After chapter questions give a start to learning to take the assessment but various levels of blooms taxonomy questions can be added to promote / advance the critical thinking skills. I've found all the terminology to be consistent. These chapters provide sufficient background, though they will be best if supplemented with a laboratory text that provides more details and images. The reviewers did not notice any bias in the text. al.). I wish that any textbooks would explain what actually happens to proteins when phosphorylated and dephosphorylated, rather than solely referring to changes in energy state. For additional free and open resources, visit http://www.openstax.org/. I teach "Cell Biology for Health Occupations" at a community college, and we currently use an abridged version of Pearson's Campbell Biology in Focus textbook. More vocabulary is presented which is a good thing to expose the students to. My review of the text found no errors and it appeared in every since to follow the standard for a quality general biology text. The text wastes no words on poetry, and moves through the material with a workmanlike approach. The book also includes various types of practice and homework questions that help students understandand applykey concepts. The facts that are presented are unlikely to change to an extent that would require a major revision any time soon. Gene flow, the movement of alleles across the range of the species, is relatively free because individuals can move and then mate with individuals in their new location. Organization of the chapters for a biology course that covers: molecules, cells, energy, cell reproduction and genetics, this text follows the conventional organization. Career connection boxes in chapters briefly describe jobs in relation to the chapter topic. I liked that current research examples were used, such as HPV infected cells in the cell division chapter, and neurons from Huntingtons patients in the Mendelian genetics chapter. Any ethical issues (for example, reproductive technologies) were handled carefully but with technical accuracy. However, most of the scientific articles cited are more than 10 years old, being the most recent article from 2015. The textbook is broadly set-up to explain the subject of biology starting from broad (chemistry/building blocks of life) to specific (organ systems) and going from simple (cells) to complex (ecology) and therefore is structured in a way that inherently builds off of the concepts from previous chapters. It compares well in this regard with widely used textbooks such as Campbell Biology, Biological Science by Freeman et al. The addition of key terms at the end of the chapters also adds a bonus summary for students to use as a resource to gauge their understanding of course concepts. If you enter into a new tab, you can see the images better in some cases, but this may not be the case for those that print out the book. All texts tend to emphasize some areas over others, and this is no exception. I liked being able to click on a link in the index or table of contents, which takes the reader directly to a specific page within the book. It would be nice to have links to the full-sized image. Often these links provide cutting edge insight into both the research and application to make the This terminology is out-of-date and reinforces student misconceptions of evolutionary change as goal-directed and progressive. Often the term is explained later (either later in the paragraph or chapter, but sometimes not until another section of the book). Frequently, however, the flow seems stilted and information presented out of context or out of order. I found this text responded well to being reordered as each section sat on its own. enzyme. For instance, in the cell reproduction chapter, the metaphase, anaphase, and telophase sections are each described using just 3 sentences. You have saved me many hours of work. molecular genetics) I don't think this book reflects very well the sate of knowledge now. One example is section 25.1, which rattles through a few basic concepts in plant biology, but without enough context to make it clear to the reader how those concepts fit into the greater story of plant evolution. Again, this seems to reflect a lack of understanding on the part of the authors, as the inaccurate terms are used consistently. 54 27 100 108 5. Most of the time you are linked right to the page you clicked off of. Here are some examples: This is an example of convection, NOT diffusion. It doesn't work very well. On page 676, the text confounds green algae and charophytes, referring to all green algae as charophytes. As a well-structured biology textbook, this book begins with a clear and short introduction to the subject, followed by a comprehensive explanation of essential subjects and concepts in a logical progression. I found few errors. How do the various kinds of microscopes differ as tools in the study of cells? read more. If you are throwing a tea party, at home, then, you need not bother about keeping your housemaid engaged for preparing several cups of tea or coffee. The text book covered all the chapters I would assign for first semester General Biology course at the college level (Molecules to Cells). better use of color). The Inheritance chapters stood out as chapters that had significantly less detail than common commercial textbooks-- a big disappointment if you love that topic and also a missed opportunity to provide more information about inheritance in humans. Although a keen student will immediately connect pH with hydrogen ion concentration, I think it would be more useful and consistent to refer to hydrogen ion gradient as it does in the text. The online accessibility allows one to search the contents of the book, making it incredibly easy to navigate. In the sections of my review below, I discuss the information my students need in relation to the content of this text. Historical aspects are important so the students recognize and understand scientific pursuits and can be inspired. A very general discussion of linkage analysis of two genes is included in chapter 13, but very little information or opportunity for practice is provided, and no information on how gene order can be inferred from linkage distances. I do have one other caveat: I had difficulty finding and accessing instructor resources. The fact that it is open source textbook, allows it to be readily modified or updated by individual instructors. We did find a few conceptual errors with minor errors scattered throughout. The overall clarity if the text is equivalent to other introductory level biology textbooks, but one feature that I feel elevates this text beyond average is the inclusion of several "Visual Connection" items in each chapter. Chapters can be taken out of order. The table of contents and index are useful, and the PDF is searchable. Overall, the organization is good, probably because it follows longstanding conventions. Likewise, the inclusion of the Chapter Summaries and Key Word definitions were highly beneficial. It is not clear what the authors mean by the subheading "Cytokine Release Affect". The sequence of topics covered, the organization of content within chapters, and each chapters ending with a list of key terms, a summary and questions contribute to the book's clarity. The next section, 19.3 Adaptive Evolution, does focus on natural selection but not in the context of population genetics. Reviewed by Anthony Arment, Professor of Biology, Central State University on 10/11/18. Many of the areas of biology are constantly changing with the ever increasing research being performed. The unit and chapter breakdown was very well done and organized appropriately. There are no problems regarding cultural insensitivity. Evolution is mentioned in Ch.1 but is not defined or explained, assuming that students already understand this complex. This text also contains chapter summaries, review questions, and critical thinking questions. ISBN. The index and glossary are fine. This single grammar mistake was found on pg. Different topics in the text are organized and presented in a logical manner that make sense from biological perspective. Reviewed by John Lepri, Professor (Biology), University of North Carolina at Greensboro on 12/5/16, Spanning 47 chapters, the OpenStax "Biology" production is as comprehensive as its competitors. Sample answer: Gatorade contains water, sugar, dextrose, citric acid, salt, sodium chloride, monopotassium phosphate, and sucrose acetate isobutyrate. I compare the chapter from Biology 2e to both the first edition Openstax Biology and a traditional introductory text from a major publisher. Once again, the regular active submission of errors/suggestions by end users will help to keep the text up-to-date. The book provides a sound and sufficiently detailed and accurate coverage of general biology and is readable, has appropriate illustrations, comes with questions and has links to supplementary external digital content (but see comment on QR codes and URLs below). Terrestrial vertebrates differ in the source of body heat and in the variation in temperature they experience and can tolerate, not in the temperature of their blood. The text book covered all the chapters I would assign for first semester General Biology course at the college level (Molecules to Cells). In fact, recent genomic evidence shows that hagfishes and lampreys form a clade, the cyclostomes: Hagfishes and lampreys share four unique miDNA families. Thats because, we at the Vending Service are there to extend a hand of help. At the end of the chapter, there is a mini glossary, defining key terms that were found throughout the chapter, which will be a nice resource for students. This book will suffice in a 2 semester biology course. It covers all the topics in sufficient detail for the student to succeed. However, while more topics are covered in the Biology textbook, the amount of comprehensiveness for each Chapter is only minimally expanded from the Concepts of Biology textbook. If xenon has an atomic number of 54 and a mass number of 108, how many neutrons does it have? There just were not enough instances for me to make a suitable comment in this area for the OER Biology textbook by Clark et al. Reviewed by Sarah Foltz, Assistant Professor, Radford University on 1/14/20, General coverage is good the text covers all of the areas Id expect to see in an introductory biology textbook, including behavior, which I find is sometimes overlooked. The chapter appears confused about how time is represented in phylogenetic trees, saying both that trees do and do not have a time axis. Biology is an extremely broad subject area to This textbook is extremely comprehensive, almost too comprehensive. There were also areas where American Indian culture could have been included but were not. This will confuse students, many of whom have trouble grasping induced fit, which is introduced on the next page. The index at the start of the text is very useful for navigation. the study of living organisms and their interactions with one another and their environments.

I have found the content for this purpose mostly comprehensive, with some need to supplement. Like most Biology textbooks, this was hit or miss for me. I did not notice any inconsistencies in this set-up or within terms. However, The themes of epigenetics, genomic research, non-coding RNA, and CRISPR-Cas gene editing were not discussed and need to be perhaps added on with additional course materials. On the other hand if the authors wanted to dwell on minutia they could say that catabolic reactions also require input of energy to overcome the energy of activation. Every summer, a new PDF of Biology is released and print stock is updated for the following Fall. Van der Waals attractions can occur between any two or more molecules and are dependent on slight fluctuations of the electron densities, which are not always symmetrical around an atom. to "large-scale" scale Biology (evolution, ecology, etc.). When more depth is required, other web sites and tutorials can be added to the students' reading materials. As such the text was lacking in examples and depicting a diverse cultural tone and images when possible. However, as with any subject, certain topics in generally biology (e.g. Definitely share, Im in that group. It is nice that links to animations and webpages are included. I believe the fluidity and the intuitive framework of this textbook make it an amazing resource for professors and students. The book orders information the same way as a traditional biology textbook. Many times, a new term is used, but there is no definition or introduction of it. Sanger sequencing is described in chapter 14 as being widely used today (p. 385). (a) element; (b) element; (c) compound; (d) mixture; (e) compound; (f) compound; (g) compound; (h) mixture. In terms of comprehensiveness, Biology 2e is very thorough. The text is easy to read and flows nicely. 5. In Mendel's chapter, the text gives a brief, insufficient description of topics like linkage and independent assortment that would confuse a student and then only at the end of the chapter does the text cover these in depth. 9781947172517. it could be conveyed that it notes ALL species variation is directly related to genetics). I noted several examples and I am sure that there are many more. Another inaccuracy has to do with wording used to describe genes and their influences on traits. glycogen. Topics are explained in a clear and concise manner. Be on the watch that the figures mirror the text, but aside from that, I look forward to using this for my class. In some places, information is repeated within a paragraph. However, since the publication date is 2013 and completion of the book was perhaps a year or two before that date the text does not include newer advances in some fast-moving areas like molecular genetics. Chapter 15, Section 15.4 stream science that seeks to expand knowledge and understanding regardless of the short-term application of that knowledge.

Archaea get very short shrift in this textbook. WebBiology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The contrast of the colors is too strong which detracts the reader from the content. In general, the content of the text is accurate. In truth, both fields are equally rigorous and important, they just study different parts of our world. To fix this, I would recommend that authors periodically check and change these links accordingly. Within chapters some of the graphics are labeled art connection, evolution connection, etc. The bar codes associated with each Link to Learning were fantastic and an excellent addition to the textbook to add additional information. (The text does link out to an online resource which invites students to click through the stages of the Krebs Cycle, however the usefulness of this tool far outweighs the confusion of the older term.). The ads might indicate endorsement by a faculty or school for certain corporations for example. The relevance of the opening figures to the chapter content is not always obvious. ISBN. I was disappointing to see that Dr. Rosalind Franklin did not get a little more ink and perhaps a photo. I found chapters and subheadings on nearly every topic that I expected to see in a biology text for majors. First, the visual portrayals: The vast majority of working scientists shown in photographs appear to be light-skinned, and mostly male-presenting.
