In Chapter 18, the text only includes the biological species concept, with no discussion of its weaknesses or limitations. For example, Figs. 2 Review Questions - Biology 2e | OpenStax Review Questions Review Questions Highlights 4. I feel the text is quite readable, concepts do not require much interpretation, and students do not appear to get lost in a concept, In no case did I find a chapter that appeared inconsistent with the overall quality of the text., nor clarity of concept, It does fit well into the organization of our curriculum, though I would prefer that the discussions of Evolution be moved to the beginning of the text, and more emphasis put on the role of Evolution in life, As above, I'd prefer that evolution be discussed in the first section, The book is very easy to read, concepts are well presented, and illustrations support the writing very effectively. Reading sections seem appropriate. read more. 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. Protists are another trouble spot, but the authors do a good job discussing the modern perspective on the protists. When talking about inherited disorders and conditions, the authors were straight-forward and sensitive with jargon related to those topics, which can read as offensive if done thoughtlessly. I reviewed the book for use in the The small text-box presentations of examples of the scientific method throughout the book were well executed. Occasionally figures also look grainy / blurry or as if they are low-resolution images (ex. That may be true for most humans, but some humans have 45 or 47. More vocabulary is presented which is a good thing to expose the students to. Otherwise I had no interface issues. Mendelian genetics and non-mendelian traits, DNA replication and repair and mitosis and meiosis I believe are covered adequately for a genetics class, but I think to use this book for a genetics class many outside resources would also need to be used (epigenetics, modern bioinformatics and next generation sequencing, genetic testing, ethics, and CRISPR-cas are some examples). They have provided the square for accessing videos, and also provide a link to videos, but sometimes the link to the videos is not available on a pc computer. There is little consistency in the images- some ar every nicely edited and some are difficult to see. (Rosalind Franklin deserves a photo next to Crick and Watson.) Having a downloadable online text allows me and others the ability to adjust light intensity and size easily on the monitor. The text appears to be culturally sensitive, but there are not very many examples of the importance of biodiversity to a variety of groups of people across the globe. However, there is quite a bit of variability from section to section in the number of review questions provided. For example, figures 7.6-7.8 all label the steps of the reactions taking place, which I found useful. 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. The online accessibility allows one to search the contents of the book, making it The index and glossary are fine. Also, there is no discussion of applications of next-generation sequencing (e,g, RNA-seq, ChIP-seq) that are commonly used today. I had absolutely no problem understanding the content in this textbook. Generally, graphics are of lower quality and some study questions are less thoughtful but links to animations and talks are a great perk! This is one of the more consistent open ed resources I've seen. I think this book is comprehensive for a general biology textbook, but it lacks some depth and breath for These are presented well with all sides considered. In Chapter 18, the text only includes the biological species concept, with no discussion of its weaknesses or limitations. The text covers essential content in sufficient detail for an introductory and/or non-majors biology survey type course. For my purposes this text does an adequate job of achieving that balance, and any deficiencies in content coverage can be made up by supplementary materials supplied by individual instructors. This text book follows the usual pattern of chapters in covering the subject of general biology. A quibble I have with this and most other textbooks is that the energy of a phosphate bond is described solely in terms of the chemistry. The text contains few grammatical and spelling errors. read more. Hopefully this is not an issue when the pdf is accessed from a desktopI'd have preferred to have all animations open in a new window. From Plant Sensory: Pathogen defense, Herbivory defense, Electrical signalling, Auxin transport, Acid growth hypothesis, Auxin regulated gene expression I didn't notice any issues. 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. Textbook content produced by OpenStax is licensed under a Creative Commons Attribution License . However, as the text reads currently, some "self-referencing" will be necessary to maintain connections among chapters and between sections within chapters. However, the scientists who are mentioned are the typical examples theres no obvious effort to include or highlight contributions from a variety of cultures or ethnic backgrounds. 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. It is written and presented in a way that students could actually use and understand. AAAS's Vision and Change concepts and competencies were not a theme in the book. The terms and phrasing used within the text were extremely consistent. plants microorganisms birds dinosaurs 5. I use Openstax Biology 2e as a textbook for my AP Bio and dual credit class. I reviewed a downloaded pdf. I felt like there was too much detail on some processes, and too little detail on other topics. There are no grammatical errors, and the language is not overly complicated in terms of sentence structure and organization. do you have any more reading guides made and if you do, could you post them? The index and glossary are fine. Additionally, sometimes terms are never explicitly defined. The 8 units this textbook, chemistry through ecology, sufficiently cover the range of topics that would be covered in an Introductory Biology series of courses.The order in which topics are addressed follows the common approach of building from the simplest level of organization up to the highest level. Each chapter and sections within chapters can easily stand alone and be assigned at any point within the semester without much problem. Again, I think this structure is typical for an introductory class. Each read more. This book will serve the purpose of introductory biology and could very well be used in place of the expensive textbooks. In contrast to some introductory biology textbooks that focus almost exclusively on humans, this text consistently includes examples from all three domains of life, making the content more applicable to students with interests in different areas of biology. 9. I 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. I found the text to be highly modular. anabolic (also anabolism) pathways that require an energy input to synthesize complex molecules from simpler ones. This is an obvious example of the fallacy of genetic determinism; its the kind of writing that instills misconceptions about the power of genes and chromosomes. read more. The text is structurally and terminologically consistent as is the writing style. Chapter 15, Section 15.4 It covered all of the subject areas that my current General Biology textbook covers. There are a number of examples of complex terms or concepts that are not clearly explained. This is not a criticism, but rather merely an observation. It is a high quality text that can provide free access to students of any income level. It was accurate and error free, to my knowledge. Whereas those books provide too much information, which can overwhelm, I wonder if this book could be a little too scant, which may make the facts feel irrelevant. The textbook is comprehensive; the extent and depth of the topics and concepts covered are at the level required in an introductory course for biology majors. I am signed up for OpenStax. ISBN. For example, the structure and function of ATP was discussed only briefly in chapter 7. Of course other organizing principles are possible, and perhaps desirable; for example the AAAS Vision and Change core concepts in biology. I did not find any issues with the interface, and especially liked the option of reading it online. I have been making them as I go, Ill add more when I can catch a breath. Reviewed by Mark Wagner, Instructor/Life Sciences, Portland Community College on 1/10/21, The text integrates in-depth concepts over a broad range of topics. The relevance of the opening figures to the chapter content is not always obvious. and Biology by Russell et al which are all well suited for a two-semester general biology sequence such as is typically taken by biology and science majors. The content appears up to date, especially in the genetics section which changes so rapidly. The process of ________ helps to ensure that a scientists research is original, significant, logical, and thorough. This text book is an excellent teaching tool. p.358 Please show the McClintock strategy as well. For my purposes, the weakest section is on phylogenetics, but I always need to supplement that section of any text.

Figures were overly simplified, yet serve the purpose. I checked several other sources just to be sure and can find no confirmation of this claim). In order to understand animal function, students must understand that the fundamental molecular tool kit of animals is largely present in single-celled eukaryotes. In other words, the new content will be a much more manageable 300 pages that will complement short videos I prepare. The sections on anatomy and physiology of the human body had a nice mix of explaining structures and functions, and linking these with disorders to make the content more relevant and interesting. a. how selective forces change the allele frequencies in a population over time In traditional fashion, the text begins by introducing the important chemical processes in cellular respiration, then working through the catabolism of a glucose molecule. The ammonia vapor will diffuse, or spread away, from the bottle, and gradually, more and more people will smell the ammonia as it spreads. No!

On page 313, the explanation of The Red Queen Hypothesis in the Evolution Connection is very weak and unclear. 1171-2 are covered with weakly explained equations and values in mm Hg. I did also have trouble opening one barcode. The text is organized in a way that most introductory instructors would be familiar with. There are no problems regarding cultural insensitivity. I felt like there was too much detail on some processes, and too little detail on other topics. Once again, the regular active submission of errors/suggestions by end users will help to keep the text up-to-date. While there were a few typos, I noted no grammatical errors in the text. Molecular biology gets some detailed figures but without much explanation in the text. At the end of the textbook, appendices (e.g., periodic table, metric system) and a comprehensive index are included. The Career Connections sections are a nice addition that students will be able to explore when considering career possibilities in science. I do believe that the text is written in such a manner that it would be relatively easy to update. One inconsistency of note is the use, or lack of use, of graphical phylogenetic hypotheses. 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. I thought many images had a random quality. The format od each section should be consistent across reading platforms. Headings and subheadings are clearly labeled so sections can be found easily. 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. It compares well in this regard with widely used textbooks such as Campbell Biology, Biological Science by read more. They are a strength of this text and, in many places, serve as the focus for the author's discussion of the topic. Clark's Biology 2e (OER) is clear and uses simple language, the topics are present with correct and up-to-date information, and include pertinent visual aids such as diagrams, pictures, and photographs. Many online books and journals offer this feature.. Reviewed by Jessalyn Sabin, Instructor, Hibbing Community College on 6/10/15, This textbook was comprehensively organized and populated with topics. While it puts major discoveries into some historical context (Mendel is discussed at length) it forgoes that context in more recent discoveries (epigenetic and its historical context). It covered all of the subject areas that my current General Biology textbook covers. Would you mind telling me how to access or who to contact please? Reviewed by Kuo-Hsing Kuo, Associate Professor, University of Northern British Columbia on 10/9/13, The text appears to be very comprehensive. I compare the chapter from Biology 2e to both the first edition Openstax Biology and a traditional introductory text from a major Sometimes a link will bring the reader to a website, and not directly to the learning video or animation. For the most part topics are presented in a logical sequence, except for the Evolution chapters. The section on temperate forests is actually inaccurate in spots, stating that deciduous trees are dominant in this biome, and omitting the fact that coniferous forest are also dominant in these forests. I found no grammatical errors, nor did I find distracting terms. This is likely a consequence of using open-access images rather than art created specifically for a textbook. read more.

The chapter appears confused about how time is represented in phylogenetic trees, saying both that trees do and do not have a time axis. WebAnswers will vary. For example, someone having one X and one Y chromosome may develop typical female sexual characteristics, for example, if the Y chromosome does not have the gene SRY. The topics speak to contemporary relevance. Therefore, the physiology section could be edited to recognize that sex steroids are not the domain of one sex specifically, as both estrogens and androgens play important roles in all humans and animals, regardless of sex or gender. Readers will get the impression that multiple authors contributed. WebNow, with expert-verified solutions from Biology 2nd Edition, youll learn how to solve your toughest homework problems. Biology 2e seems to go into slightly more detail in some places, especially in regard to molecular biology. Overall this text covers each topic in adequate detail and provides enough detail and content for a two semester coverage of biology for majors, especially if this text is used alongside additional instructor input and labs. These are students with majors and interests that include biology, biochemistry, neuroscience, kinesiology, environmental science, and pre-professional students who aspire to attend professional graduate programs in medicine, veterinary medicine, dentistry, and allied health care. read more. Figures are wider and slightly larger in the pdf version, but labeling is still difficult to read. Overall, it a text that is a good value for students to learn basics of biology. I found my topic if the end of the keyword was different from the text but a misspelling in the middle of the word returned no matching results. The book had a slightly heavier bias toward molecular techniques rather than organismal or behavioral science, but that field appears to be the current zeitgeist, maintaining the book's relevancy. The book is not culturally insensitive or offensive. Some current topics, such as epigenetics and biotechnology, were covered very well and Overall, I found this to be an exceptional textbook option for the cost. Bar codes are used in many places for easy conversion as media changes. Furthermore, these duplicates appear to reference different pages. This textbook covers the typical introductory biology course topics for biology majors, including chemistry, cells, genetics, evolution, biodiversity, plant and animal form and function, and ecology. Only issues I've found are in the accuracy of illustrations -- several are mis-labeled. This is well done. hypothesis variable theory control 6. Content is presented in a logical fashion, building upon one another as the book progresses. The web based interface is simple and clean, and not overly complicated. It also makes it easier for a student to be able to navigate through the text and find a particular idea or piece of information that they may be searching for. However, it is a reality that not all students will be facile with such foundational knowledge, so inclusion of these terms and figures in subsequent chapters reduces compromising student understanding. Images and figures need revision as many are displaying with poor resolution in the pdf version. Any ethical issues (for example, reproductive technologies) were handled carefully but with technical accuracy. read more. Also, the glossary has terms that are not fully defined.
