Question 1

Which of the following best describes the relationship between structure and function in biological systems?

Accepted Answer

Structure provides clues about what something does and how it works, and understanding function can reveal insights into structure.

Question 2

Which of the following is NOT a unifying theme in biology?

Accepted Answer

Randomness

Question 3

A scientist observes that a population of bacteria can survive in extremely salty environments. Which domain of life is this population most likely to belong to?

Accepted Answer

Domain Archaea

Question 4

Which of the following statements about cells is correct?

Accepted Answer

Prokaryotic cells lack a nucleus and membrane-bound organelles.

Question 5

Which process is an example of negative feedback regulation in living systems?

Accepted Answer

The output of a process inhibits the initial stimulus, maintaining homeostasis.

Question 6

Which of the following best explains why evolution is considered a core theme in biology?

Accepted Answer

Evolution explains the unity and diversity of life through descent with modification.

Question 7

A researcher is studying the inheritance of a genetic trait. Which molecule is most directly involved in the transmission of hereditary information?

Accepted Answer

DNA

Question 8

Which equation best represents the process of cellular respiration?

Accepted Answer

$$\mathrm{C_6H_{12}O_6$} + 6\mathrm{O_2$} ightarrow 6\mathrm{CO_2$} + 6\mathrm{H_2O} + 	ext{energy}$$

Question 16

Which of the following best describes the role of feedback regulation in biological systems?

Accepted Answer

Feedback regulation ensures smooth integration of all parts by adjusting processes based on output.

Question 17

Which of the following is a correct statement about the domains of life?

Accepted Answer

Domain Archaea includes prokaryotes that often live in extreme environments.

Question 18

Which of the following is a real-world example of the application of the scientific method in biology?

Accepted Answer
