Accepted Answer

Measurements of plant height in centimeters

Question 12

Which of the following is a function of enzymes in biological systems?

Accepted Answer

They accelerate chemical reactions by lowering activation energy.

Question 13

Which of the following is an example of positive feedback?

Accepted Answer

The aggregation of platelets during blood clotting amplifies the response.

Question 14

Which statement best describes the process of induction in scientific reasoning?

Accepted Answer

Drawing general conclusions from a large number of specific observations.

Question 15

Which of the following is a direct consequence of burning fossil fuels since the Industrial Revolution?

Accepted Answer

Increase in atmospheric $$CO_2$$ levels

Question 16

Which of the following best explains why reductionism is useful in biology?

Accepted Answer

It helps break down complex systems into manageable parts for study.

Question 17

Which of the following is NOT a criterion for a scientific hypothesis?

Accepted Answer

It must be supported by supernatural explanations.

Question 18

Which of the following is a real-world example of an emergent property in an ecosystem?

Accepted Answer

The cycling of nutrients through interactions among organisms and the environment

Question 19

Which of the following best describes the role of evolution in biology?

Accepted Answer

It accounts for both the unity and diversity of life.

Question 20

A scientist uses the following equation to calculate the rate of photosynthesis: $$R = \frac{\Delta O_2$}{\Delta t}$$, where $$R is $$the rate, $$\Delta O_2$ is the change in oxygen concentration, and $$\Delta t$$ is the change in time. If $$\Delta $$O_2 = 20$ mg/L and $$\Delta t = 4$$ hours, what is the rate of photosynthesis?

Accepted Answer

$$R = 5 mg/L/hr$$
