Question 5

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

Accepted Answer

The structure of a biological component determines its function.

Question 6

Accepted Answer

Random assembly of parts

Question 7

In a scientific experiment testing the effect of a new fertilizer on plant growth, which is the dependent variable?

Accepted Answer

Plant height measured after two weeks

Question 8

Which of the following best describes a scientific theory?

Accepted Answer

A broad explanation supported by a large body of evidence.

Question 9

Which of the following is an example of inductive reasoning?

Accepted Answer

After observing that all swans in a pond are white, concluding that all swans are white.

Question 10

A scientist observes that a flashlight does not work. She hypothesizes that the batteries are dead. What is the next logical step in the scientific method?

Accepted Answer

Replace the batteries and test if the flashlight works.

Question 11

Which of the following best explains how evolution accounts for both the unity and diversity of life?

Accepted Answer

Organisms share common traits due to descent from a common ancestor, but differences arise from heritable changes over time.

Question 12

Which of the following is an example of a systems biology approach?

Accepted Answer

Measuring the effect of an invading insect on oak trees and decomposer fungi in the soil.

Question 13

Which of the following best describes the role of DNA in the continuity of life?

Accepted Answer

DNA stores heritable information that is passed from one generation to the next.

Question 14

A researcher wants to test the hypothesis that red light increases plant growth more than green light. Which of the following is the best experimental design?

Accepted Answer

Grow plants under red light and compare their height to plants grown under green light, keeping water, soil, and temperature constant.

Question 15

Which of the following is an example of quantitative data?

Accepted Answer

The fish is 7.12 cm long.

Question 16

Which of the following statements about scientific hypotheses is correct?

Accepted Answer

A hypothesis must be testable and falsifiable.

Question 17

Accepted Answer

To ensure that only the variable of interest affects the outcome.

Question 18

Which of the following best describes the difference between a hypothesis and a theory in science?

Accepted Answer

A hypothesis is a tentative explanation that can be tested, while a theory is a well-supported explanation that integrates many observations and hypotheses.

Question 19

Which of the following is an example of deductive reasoning?

Accepted Answer

All mammals have hair. A whale is a mammal. Therefore, a whale has hair.

Question 20

Which of the following best explains why a bicycle assembled from parts can move, but a pile of the same parts cannot?

Accepted Answer
