Concept explainers
For each statement, identify which major theme is evident (the relationship of structure to function, information flow, pathways that transform energy and matter, interactions within biological systems, or evolution) and explain how the statement relates to the theme. If necessary, review the theme descriptions in this chapter.
11. Although green sea turtles consume a lot of vegetation, they get few nutrients from each mouthful, requiring them to graze frequently.

- Explain the major evolutionary advantage for humans and other animals (compared to plants) of storing most of their energy as fat, instead of carbohydrates or proteins. [Answer is not providing insulation or any type of protection or cushioningarrow_forwardJust answer letter B a) Describe the two basic means by which living organisms obtain energy from the environment. Identify one example of each, and explain at least one similarity and one difference in biological structure that supports these two means of dealing with energy needs. b) Construct a diagram to show the:-direction of energy flow-type of energy flowing-release of heat-impact of the sun on energy flow-between the two classes of organisms you described above. Justify the inefficiency of this system.arrow_forwardThe smallest unit of biological structure that meets the functional requirements of “living” is the ________.arrow_forward
- In school, students tend to do a lot of activities, research, and assignments in all subjects. Once the deadline is near, they tend to work UNDER PRESSURE. They get easily mad and complain about everything. Why do you think this thing happen? How will you relate this scenario to the earth's interior that is also under pressure? Answer the following questions, explain your answers by citing your references and evidences (make your answer as brief as possible and underline the key words/ phrases) At present, a significant increase in greenhouse gases and atmospheric temperature is being felt. How will this affect the activities of plants, animals, microorganisms, etc. in terms of photosynthesis? (recall topic on enzymes) If energy is never destroyed, why do we “run out of energy” at the end of a race? Give the different factors that can affect the rate of photosynthesis. How does different light intensities affect the rate of photosynthesis? Why do you think is the coupling…arrow_forwardConsider the two passages below. Which one do you agree with, and why? Support your argument using examples from experience and observation. In approximately one paragraph, defend one position, then refute the other. Or take a position somewhere between them and explain your point of view. In The Omnivore’s Dilemma, Michael Pollan quotes a food industry executive, Gene Kahn, regarding our food choices: “This is just lunch for most people. Just lunch. We can call it sacred, we can talk about communion, but its just lunch.” In Just Food, James McWilliams “offer(s) a vision of sustainability that assumes that, as socially conscious consumers, we’re prepared to take on more complexity in the quest to achieve an environmentally responsible diet.”arrow_forwardELLABORATE AND DIFFERENTIATE the following theories in terms of each’s MAIN IDEA, and REASONABLE SUPPORT / EVIDENCE.1) Oparin-Haldane hypothesis2) Gene-First Hypothesis3) Metabolism-First Hypothesis4) Organic Molecules from Outer Sparrow_forward
