Indicate whether the statement is true or false. If it is false, change the identified word(s) to make the statement
true. 1. Much of our understanding of how large organisms respond to environmental variation is based on observations
of model species. 2. Protists do not constitute a kingdom because they do not share a unique common ancestor. 3. The process by which producers harness electromagnetic energy and convert it into chemical energy is cellular
respiration. 4. Internal body temperature in humans is regulated primarily by behavioral mechanisms. 5. The process by which RNA is converted into protein is called transcription . 6. Favorable mutations may produce adaptations . 7. Although Darwin and Wallace understood the central importance of heritability among organisms to the process
of evolution, they could not explain how new variations arose or how they were passed to the next generation. 8. The example of an adaptation provided by the rock pocket mice illustrates the observation that genetic
differences often develop between individuals. 9. Researchers who study the impact of nitrogen-based fertilizers on increasing crop growth use applied research
methods. 10. Populations can be described in terms of their diversity and stability.
Indicate the answer choice that best completes the statement or answers the question. 11. You are studying an ecosystem on your campus. After a solid base of carefully observed and described facts,
your next step would be to ____.
a. make more observations
b. make a hypothesis
c. share your data with others
d. wait for instructions
e. design an experiment 12. The group that is the most inclusive and has recently been added to the classification scheme is ____.
a. animalia
b. kingdom
c. eukarya
d. protista
e. domain
