WebAnswer Both systems involve chemical messengers that must interact with receptors in order to have an effect. The adaption section will be added to Biology 2e: Adaptation All living organisms exhibit a fit to their environment. All Right Reserved. Overall, a timely discussion of modern issues is demonstrated well throughout the text. Why are two base pairs (T-A and incorrectly labeled C-G) shown? The pdf is also easily searchable when opened with the Preview app on a Mac. On page 676, the text confounds green algae and charophytes, referring to all green algae as charophytes. The modules make sense, are well organized, and (mostly) self-sufficient. OpenStax is part of Rice University, which is a 501(c)(3) nonprofit. Urochordate and vertebrate embryos share a novel embryonic tissue layer: migratory neural crest cells. In general, it hits right at the level its aimed at. I also like the frequent inclusion of the "Career Connection" items -- they're very accessible and our students need to know there are many, many careers in biology beyond healthcare, teaching, and academic research. thank you so much! I could probably use them! Although the book will be most naturally adoptable for courses that deliver content in this same order, the book should be flexible enough to allow instructors to adapt it to their own ordering of topics. The text is organized in a way that most introductory instructors would be familiar with. Even less accurate, the text goes on (p. 386) to say that Sangers genome sequencing has led to a race to sequence human genomes at rapid speed and low cost, often referred to as the $1000-in-one-day sequence. Here also, we are willing to provide you with the support that you need. While some topics and visuals are redundant across chapters, this also helps with modularity of the text. 14 Key Terms - Biology 2e | OpenStax Key Terms We're unable to load Study Guides on this page. On the instructor side, anyone who relies on powerpoints, especially new instructors, would find the lack of included images to be challenging and the need to add images will raise some issues around using copyrighted material from other sources. I believe this is where the instructor comes in to highlight other scientists and contributors to the field. Conclusion. 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. In the sections I read closely and thoroughly I found no errors. Further, some comprehension questions at the end of chapters would continue on the next page making it hard to understand what the answer choices were. You can even purchase a bound copy from Amazon for around $60, which is very reasonable for a textbook. WebBiology 2e (2nd Edition) Book Edition. The chapters are organized into 8 main units. I hardly found any grammatical errors in the sections read, but found the text easy to follow and understand. This will probably be apparent especially in the molecular genetics topics. The book is internally consistent between different sections in spite of the multi-author origin of the content. I have not found any errors within the text. There are a few areas that I am pleasantly surprised by the detail included, but other areas where I am a little surprised to see detail lacking. Just something to think about if you want to use it for seated sections on campus. The Biology 2e text is comprehensive without being overwhelming and provides a similar organization and logical flow as the previous text.

Another advantage of online textbooks. (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.). Reviewed by Jessalyn Sabin, Instructor, Hibbing Community College on 6/10/15, This textbook was comprehensively organized and populated with topics. I found the book to be consistent in regards of terminology and layout, definitions of terms, and general chapter scheme. I found no problems with the links within in the text and I was surprised by this since I myself often have issues year to year with broken links. That is confusing. Overall the writing is clear. The content, as least in the chapters I cover, is extremely similar to my current Web resources have a notoriously short longevity and links to external sources need updating, so their inclusion makes regular updating essential if only for that reason. The book is easily adaptable. Modularity is good! But an editor had to step in and work for consistency. ISBN. 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. Students would benefit from learning about totipotency and tissue culture, development and growth, phytohormones and associated signaling mechanisms etc., in plants, Each chapter is provided with much useful key terms and definitions, chapter summary and review questions. WebBiology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. As noted above, I like the logic of the subdivisions of each chapter (not too many, not huge blocks of text) and the amount of material on one page is less than I feel most other books offer. The option to purchase a bound copy is great for students who choose to do so. Even when using the material in a different order than presented in the text, it does not affect the continuity and connectedness of the material. One feature I like is that students can explore these concepts in greater depth by following in-text links to online resources. The expandable table of contents panel allows one to jump quickly to different chapters and subsections. Yes it is but a lack of internal referencing is evident. Updating with new information should be relatively straightforward, but as with all texts, the challenge will be to maintain brevity. I was wondering if you have Chapter 12 (Genetics)? Figure 1.16 is one example where the display issues make the figure almost useless. Mention of the various topics relating to the globalization of science may benefit the students coming from outside of US. Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text uses straightforward language, maintaining clarity in this field full of specialized vocabulary. Viruses are not considered living because they ________. This textbook has some such examples which is commendable. This book follow the traditional, and most widely used, manner of organization for the sequence of chapters and topics, which allows for a logical flow of content. Much of the time, the text took on a more conversational tone than I was expecting, which I feel will appeal to readers. I have found the content for this purpose mostly comprehensive, with some need to supplement. The 4 rating is because there isn't the same consistent visual "language" in the illustrations as there is in a commercial textbook. There are no issues with the download at any time and website does reminder the reader to use the chrome or any other web browser than IE. It does not however include the latest information on gene editing. At the end of each chapter, there is a glossary of key terms, chapter summaries (divided by section), visual connection questions, multiple-choice review questions, and short-answer critical thinking questions. On page 24, the term germline cells is used but is not clearly defined. However, within individual chapters, the topics may not always be presented in the most logical order. Additionally, I like the summary tables at the end of many sections and/or chapters (particularly cells and membranes). I personally would put mitosis and meiosis and heredity before metabolism but was able to rearrange chapter orders with no difficulties. I focused in on Chapter 15: Genes and Proteins. Also within chapters are QR codes and URLs that take the reader to animations and movies on the OpenStax website. 5. If there are provisions for regular revisions of the textbook these issues can be addressed easily. These are concise and provide a better big-picture summary than the text I currently use, where students often become overwhelmed and lost in the details. This would be what good instructors always do, but new instructors often have to take more of their clues from the text. 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. Unfortunately, it is also uneven relative to the printed alternatives. Navigation within the digital book was problem-free. The textbook explains very complex topics in a comprehensive manner and appears to be designed for early term biology and Often the term is explained later (either later in the paragraph or chapter, but sometimes not until another section of the book). 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. hydrophobic and Hydrophobic) were noted in the index. It would be nice to see more career examples and spotlights on diverse scientists, but this would make the text hard to keep updated and current, so I can understand it not being done. The figures are simplistic, which for some topics is helpful like meiosis, but in other cases I think more details in the figure would be helpful. storage carbohydrate in animals. Topics are explained in a clear and concise manner. The format and terminology are consistent across units and chapters. There is no reason to dwell on this metric, as the grammar and English were fine in all the chapters I read. Each section is very short. It seems clear that different chapters are written by different peoplesome of the chapters (for example, on the immune system) are exceptionally detailed, whereas others (e.g., on evolution and speciation) are a bit more bare-bones, but all the bases are covered. The index is easy to use in both the PDF and online Inclusion of well-labeled figures, tables, and charts throughout the text to compare and contrast structures and to help students visualize processes are particularly helpful. 4 0 obj The graphics were small and not at all rich. The content covers the foundational concepts and therefore are unlikely to change or need radical revising in the short term. Consistency is good but not great. I did not find any issues with the interface, and especially liked the option of reading it online. The text book used various external resources with both female and male voices. You are welcome to use them, though I am not affiliated with openstax, these are just things I put together to get my students to read. (b) [Pt(NH3)2FCl]\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{FCl}\right][Pt(NH3)2FCl]. Links to Animations The sentence structure and vocabulary beyond the scientific terms are simple enough that even ESL college students should be able to glean information. The structure of the text is similar to most text books for this level of biology and the units are divided appropriately. (a) element; (b) element; (c) compound; (d) mixture; (e) compound; (f) compound; (g) compound; (h) mixture. It is refreshing to see a discussion of epigenetics in detail as this is often missing from upper level genetics text books. The abstracts are a good concise summary of what the chapter intends. The terms warm-blooded and cold-blooded are used throughout the text, e.g., page 749: The mostly cold-blooded dinosaurs ceded their dominance of the landscape to more warm-blooded mammals. These terms are highly inaccurate. Overall the text is not overly technical, but sometimes it fails when it is not technical enough. The online format should make it easy to update.There are no peer reviewed references for each chapter so there is no way to know that the material is scientifically accurate. Overall, this book provides what I need content-wise for my introductory courses. More importantly, however, rapid advances are made in many aspects of modern biology, most notably in molecular genetics, but even other areas are undergoing change from the application of molecular approaches and new discoveries. anabolic (also anabolism) pathways that require an energy input to synthesize complex molecules from simpler ones. The vast majority of the content is accurate. The index has links to the relevant sections, which is helpful, and each chapter contains a Key Words section. I noted several examples in which material is explained clearly in one part of the text, with inaccurate or inconsistent information in other places. 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. It covers all the topics in sufficient detail for the student to succeed. I thought many images had a random quality. 122 an entire sentence was inside the parentheses. WebCh. While there were a few typos, I noted no grammatical errors in the text. Many of the links are to YouTube videos, some of which are embedded and play directly in the text, whereas others open in a new tab. For me, a text book is a resource of basic information that allows the students to learn a bit on their own (the critical basics) before applying their knowledge to in class activities. In some places, information is repeated within a paragraph. There is coverage of all levels of organization and no bias is evident in coverage of molecular versus ecological topics. The labeling is not clear in many figures, the font type is distracting, labels have shadows, and they are distorted or blurry. If xenon has an atomic number of 54 and a mass number of 108, how many neutrons does it have? There are a few errata, but they were mostly grammatical errors. The sentence conveys an implicit idea that ALL variation in a species is attributable to genes. There were also some chapters that were sparse of images, including the genetics unit - in particular the information about cancer. A person notices that her houseplants that are regularly exposed to music seem to grow more quickly than those in rooms with no music. Within chapters some of the graphics are labeled art connection, evolution connection, etc. Most of the images are clear and appropriately arranged. In Fig 5.4 a new illustration of bilayer is needed because the current diagram is not very clear. Page 149). I have not read each chapter, but the few I did, I did not find errors. (Examples include: why do we use action potentials for internal communication instead of direct current or signaling using photons; why are our skeletons made of calcium and phosphate rather than other minerals, and why do mammals use an inefficient tidal lung while birds use an efficient one-way flow that can extract more oxygen than mammals?) Most components of the interface were easy to navigate and only show minor distortion in few cases. One, the figures are sometimes bare-bones. For example, in the photosynthesis chapter, the explanation of the light reactions is much more straightforward than in my book. Although this book had 6 Senior Contributors and a large number of Faculty Contributors, the editing was done in a manner that kept the framework and terminology consistent throughout the book. This review will focuses specifically on a representative chapterin this case, Chapter 7: Cellular Respiration. Im sure there were many others. In fact, I would argue that a strength of digital textbooks is the ability to quickly zip from one section to another with a click. Cell biology gets more cursory coverage and evolution is surprisingly How do the various kinds of microscopes differ as tools in the study of cells? It focuses on many broad aspects of biology such as Chemistry, Cell biology, Ecology and Geology. Aside from the figures, other aspects of the interface function well. Should our understanding of cellular respiration or fermentation change, the chapter should be easy to update. Some of these are laced with ads that might indicate endorsement by a school or faculty and could be offensive to a student. 2. It is not clear what the authors mean by the subheading "Cytokine Release Affect". The navigation bar is simplistic but does the job. On page 242, the discussion of CAM and C4 photosynthesis is far too brief. I dont think this type of writing will attract any students to this type of text over a paper textbook. This alone happens at a frequency of perhaps 1 in 20000, and there are a great number of additional ways in which a persons chromosomes might not follow the statistically most common pattern. Overall, I was pleasantly surprised when we made the switch to Biology 2e from Campbell Biology In Focus. Later, the text (page 530) says, Some structures are both analogous and homologous: the wings of a bird and the wings of a bat are both homologous and analogous. True, but the author does not explain why these structures are both homologous and analogous! Within the evolution section, no outwardly offensive material was presented that would make conversations difficult with students of a variety of belief systems. So it will remain relevant for the long term, as general biology subjects do not change very much anymore. I enjoyed the navigation of the text via the left-hand side contents menu. This error appears to be due to a change in the figure from the first edition which was not accompanied by a corresponding change to the caption.) We call a molecule that binds up excess hydrogen ions in a solution a(n) ________. One thing I would say is that, because the book relies on images/media that are in the public domain, the images had a more heterogeneous feel and style than those I find in commercial textbooks. I found that the level of detail is appropriate for a lower level undergraduate biology course. Again, this seems to reflect a lack of understanding on the part of the authors, as the inaccurate terms are used consistently. It was accurate and error free, to my knowledge. However, some topics at least for a genetics class, I believe do not have enough detail (examples gene expression, sequencing). Reviewed by Karen Sirum, Associate Professor, Bowling Green State University on 2/1/18, Core concepts for introductory level college course are addressed in sufficient detail, without overly complicating the material for this audience. This makes it easy to expand on particular topics, replace a section with other reading, and tailor the text to the objectives of a course. This text book is an excellent teaching tool. The text is up to date and addresses relevant and contemporary issues. Sections are numbered within chapters, which makes it easier to assign parts of chapters. For the most part topics are presented in a logical sequence, except for the Evolution chapters. 17. While there is far more content than I cover in a 10-week term, the ability to customize this excellent text for specific use is invaluable. Occasionally a link to a video is not available but that is the nature of any online content and instructor should prepare to handle it accordingly. Cultural issues are handled appropriately.
