Question 1

Which of the following best describes an emergent property in biological systems?

Accepted Answer

A property that arises only when individual components interact at higher levels of organization.

Question 2

Which of the following statements about the flow of energy and cycling of matter in ecosystems is correct?

Accepted Answer

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

Question 3

A scientist observes that a certain population of mice has lighter fur on sandy beaches and darker fur inland. Which hypothesis best explains this observation based on natural selection?

Accepted Answer

Predators are more likely to catch mice whose fur contrasts with their environment, leading to higher survival of camouflaged mice.

Question 4

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

Accepted Answer

Gravity

Question 5

Which of the following best describes the process of gene expression?

Accepted Answer

The process by which information from a gene is used to synthesize a functional protein.

Question 6

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

Accepted Answer

Eukarya includes plants, animals, fungi, and protists.

Question 7

A researcher is testing the effect of a new fertilizer on plant growth. She sets up two groups: one receives the fertilizer, and the other does not. What is the independent variable in this experiment?

Accepted Answer

The application of the fertilizer.

Question 8

Which of the following best illustrates the concept of structure-function correlation in biology?

Accepted Answer

The double helix structure of DNA allows it to store genetic information efficiently.

Question 9

Which of the following is an example of negative feedback regulation in the human body?

Accepted Answer

The secretion of insulin decreases blood glucose levels, which in turn reduces insulin secretion.

Question 10

Which of the following statements about scientific theories is correct?

Accepted Answer

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

Question 11

Which of the following best describes the difference between prokaryotic and eukaryotic cells?

Accepted Answer

Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not.

Question 12

Which of the following is an example of inductive reasoning in biology?

Accepted Answer

Predicting that all mammals have hair because you have observed that all dogs, cats, and rabbits have hair.

Question 13

Which of the following is a real-world example of positive feedback?

Accepted Answer

Amplification of labor contractions by oxytocin during childbirth.

Question 14

Which of the following best explains why DNA is considered the universal genetic language?

Accepted Answer

All organisms use the same four nucleotide bases in their DNA.

Question 15

A population of finches on the Galápagos Islands evolves different beak shapes to exploit different food sources. This is an example of:

Accepted Answer

Adaptive radiation

Question 16

Which of the following is NOT a property of life?

Accepted Answer

Spontaneous generation

Question 17

Which of the following best describes the relationship between science and technology?

Accepted Answer

Science aims to understand natural phenomena, while technology applies scientific knowledge for practical purposes.

Question 18

Which of the following is an example of a controlled experiment?

Accepted Answer

Comparing the survival of camouflaged and non-camouflaged mouse models in different habitats.

Question 19

Which of the following is a correct application of deductive reasoning in biology?

Accepted Answer

If all cells come from pre-existing cells, then a new cell observed in a tissue must have arisen from another cell.
