The Tenth Edition of the best-selling text Campbell BIOLOGY helps launch you to success in biology through its clear and engaging narrative, superior pedagogy, and innovative use of art and photos to promote student learning.
The Tenth Edition helps you develop a deeper understanding of biology by making connections visually across chapters and building the scientific skills needed for success in upper-level courses.
-New Make Connections Figures pull together content from different chapters visually, helping you see “big picture” relationships.
-New Scientific Skills Exercises in every chapter use real data to build key skills needed for biology, including data analysis, graphing, experimental design, and math skills.
-New examples show you how our ability to sequence DNA and proteins rapidly and inexpensively is transforming every subfield of biology.
Sample questions asked in the 10th edition of Campbell Biology:
FOCUS ON EVOLUTION In a short essay (100-150 words), describe Darwin’s view of how natural selection resulted in both unity and diversity of life on Earth. Include in your discussion some of his evidence. (See tips for writing good essays and a suggested grading rubric in the Study Area of MasteringBiology under ‘’Writing Tips and Rubric’’.)
The most important adaptive advantage associated with the filamentous nature of fungal mycelia is a. the ability to form haustoria and parasitize other organisms. b. the potential to inhabit almost all terrestrial habitats. c. the increased chance of contact between mating types. d. an extensive surface area well suited for invasive growth and absorptive nutrition.
SCIENTIFIC INQUIRY Although skeletal muscles generally fatigue fairly rapidly, clam shell muscles have a protein called paramyosin that allows them to sustain contraction for up to a month. From your knowledge of the cellular mechanism of contraction, propose a hypothesis to explain how paramyosin might work. How would you test your hypothesis experimentally?
MAKE CONNECTIONS Many new animal body plans emerged during and after the Cambrian explosion. In contrast, cnidarians today retain the same diploblastic, radial body plan found in cnidarians 560 million years ago. Are cnidarians therefore less successful or less “highly evolved” than other animal groups? Explain. (See Concepts 25.3 and 25.6.)
Draw IT The graph here shows the pH difference across the inner mitochondrial membrane over time in an actively respiring cell. At the time indicated by the vertical arrow, a metabolic poison is added that specifically and completely inhibits all function of mitochondrial ATP synthase. Draw what you would expect to see for the rest of the graphed line, and explain your reasoning for drawing the line as you did.
Lipid-soluble signaling molecules, such as aldosterone, cross the membranes of all cells but affect only target cells because a. only target cells retain the appropriate DNA segments. b. intracellular receptors are present only in target cells. c. only target cells have enzymes that break down aldosterone. d. only in target cells is aldosterone able to initiate the phosphorylation cascade that turns genes on.
