Accepted Answer

Homeostasis

Question 4

In the hierarchy of biological organization, which level comes directly after 'organ systems'?

Accepted Answer

Question 5

Which of the following statements about DNA is correct?

Accepted Answer

DNA is the genetic material found in chromosomes.

Question 6

A negative feedback mechanism in biology is best illustrated by which of the following scenarios?

Question 7

Which domain of life includes organisms that absorb nutrients from their environment and are eukaryotic?

Accepted Answer

Eukarya

Question 8

Which of the following best explains why 'life' is considered an emergent property at the cellular level?

Accepted Answer

Because the cell is the smallest unit where all properties of life are present due to the interaction of its components.

Question 9

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 dogs, cats, and rabbits have hair.

Question 10

Question 11

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

Accepted Answer

Technology applies scientific knowledge for specific purposes.

Question 12

Which of the following is a correct statement about natural selection?
