Acquiring and using energy

Question 12

Which of the following statements about the classification of life is correct?

Accepted Answer

Bacteria and Archaea are both prokaryotic domains

Question 13

A biologist discovers a new organism that can reproduce, respond to stimuli, and evolve, but cannot maintain homeostasis. According to the definition of life, how should this organism be classified?

Accepted Answer

As a non-living entity

Question 14

Which of the following best illustrates the importance of evolutionary relationships in biological classification?

Accepted Answer

Classifying organisms according to their evolutionary ancestry

Question 15

If a scientist is studying the effect of temperature on enzyme activity in bacteria, which property of life is most directly being investigated?

Accepted Answer

Response to stimuli

Question 16

Which of the following is a multi-step example of how living things acquire and use energy?
