Accepted Answer

All living organisms are made from cells, which are the basic unit of structure and function.

Question 5

Which domain includes organisms that are prokaryotic and often live in extreme environments?

Accepted Answer

Domain Archaea

Question 6

In the context of scientific inquiry, which reasoning method is used to derive generalizations from a large number of specific observations?

Accepted Answer

Inductive reasoning

Question 7

Which of the following best explains why the beach mouse and inland mouse have different fur colors?

Accepted Answer

Natural selection favored fur colors that provided camouflage in their respective environments.

Question 8

Which of the following is NOT one of the five unifying themes of biology?

Accepted Answer

Reproduction

Question 9

A controlled experiment is designed to test the effect of a single variable. Which group receives the variable being tested?

Accepted Answer

Experimental group

Question 10

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

Accepted Answer

The structure of a biological component provides clues about its function, and knowing its function gives insight into its structure.

Question 11

Which of the following is a correct statement about scientific theories?

Accepted Answer

A theory is supported by a large body of evidence and can lead to new hypotheses.

Question 12

Which of the following best illustrates the cycling of matter in an ecosystem?

Accepted Answer

Animals eat plants and release nutrients and minerals back to the soil through waste products.

Question 13

Which of the following is a real-world example of how science and technology are interdependent?

Accepted Answer

The discovery of DNA structure led to advances in genetic testing for hereditary diseases.

Question 14

Which of the following is a correct representation of the hierarchical levels of biological organization from smallest to largest?

Accepted Answer

$$	ext{Molecule} ightarrow 	ext{Organelle} ightarrow 	ext{Cell} ightarrow 	ext{Tissue} ightarrow 	ext{Organ} ightarrow 	ext{Organism}$$

Question 15

Which of the following is a characteristic of eukaryotic cells but NOT prokaryotic cells?

Accepted Answer

Presence of membrane-enclosed organelles such as a nucleus.

Question 16

Which of the following is an example of a model organism commonly used in biological research?

Accepted Answer

Drosophila melanogaster (fruit fly)

Question 17

Which of the following best explains why diverse viewpoints are valuable in science?

Accepted Answer

They lead to more robust, valuable, and productive scientific interchange.

Question 18

Which of the following is a correct statement about the unity and diversity of life?

Accepted Answer

Evolution explains both the unity and diversity of life by descent with modification from common ancestors.

Question 19

Which of the following is a correct example of deductive reasoning in scientific inquiry?

Accepted Answer

If all organisms are made of cells, and humans are organisms, then humans are made of cells.

Question 20

Which of the following best describes the role of decomposers in an ecosystem?

Accepted Answer

They break down dead organisms and return minerals to the soil.
