Question 3

A scientist observes that a population of mice living on white sand dunes has lighter fur than a population living inland on dark soil. Which scientific process is best illustrated by this observation?

Accepted Answer

Gathering qualitative data

Question 4

Which statement about the flow of energy and cycling of chemicals in an ecosystem is correct?

Accepted Answer

Energy flows through an ecosystem, entering as light and exiting as heat, while chemicals cycle within the ecosystem.

Question 5

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

Accepted Answer

Analyzing a biological structure gives clues about what it does and how it works.

Question 6

Which of the following is a correct statement about prokaryotic and eukaryotic cells?

Accepted Answer

Eukaryotic cells have membrane-enclosed organelles, including a nucleus.

Question 7

Which process describes the conversion of genetic information from DNA to a functional protein?

Accepted Answer

Gene expression

Question 8

Accepted Answer

The coloration of the mouse models

Question 9

Which domain includes organisms that are mostly single-celled and are classified into several groups, some of which are more closely related to plants, animals, or fungi than to each other?

Accepted Answer

Domain Eukarya

Question 10

Which of the following is an example of negative feedback regulation in biological systems?

Accepted Answer

A process in which the accumulation of an end product slows down the process that produces it.

Question 11

Which of the following best describes the scientific definition of a theory?

Accepted Answer

A theory is broader in scope than a hypothesis and is supported by a large body of evidence.

Question 12

Which equation best represents the flow of energy in photosynthetic organisms?

Accepted Answer

$6CO_2 + 6H_2O + light \rightarrow C_6H_{12}O_6 + 6O_2$

Question 13

Which reasoning process is used when a scientist makes generalizations from a large number of specific observations?

Accepted Answer

Ghosts fooled with the desk lamp.

Question 17

Which of the following best describes the process of natural selection?

Accepted Answer

Individuals with traits best suited to their environment are more likely to survive and reproduce, leading to adaptation over time.

Question 18

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

Accepted Answer

The discovery of DNA structure led to advances in DNA technology, such as testing for hereditary diseases.

Question 19

Which of the following is a correct application of the scientific method in a medical scenario?

Accepted Answer
