Question 6

The cell theory, which states that all organisms are composed of cells, was first proposed by:

Accepted Answer

Matthias Schleiden and Theodor Schwann

Question 7

Which of the following is an example of the inductive method in science?

Accepted Answer

Making numerous observations until confident generalizations can be made.

Question 8

A scientist claims that a new drug lowers blood pressure. According to the principle of falsifiability, what must be true about this claim?

Accepted Answer

There must be a way to specify what evidence would prove the claim wrong.

Question 9

Which of the following is NOT a characteristic that distinguishes living organisms from nonliving objects?

Accepted Answer

Double-blind method

Question 15

Which of the following is the correct order of the hierarchy of human structural complexity, from largest to smallest?

Accepted Answer

Organism, organ system, organ, tissue, cell, organelle, molecule, atom

Question 16

Which of the following is an example of anatomical variation among humans?

Accepted Answer

Some individuals have an atypical number of certain organs, such as kidneys.

Question 17

Which of the following is a reason why precise spelling is important in anatomy and physiology?

Accepted Answer

Many terms are spelled similarly but have very different meanings.

Question 18

A scientist is designing an experiment to test a new drug. Why is it important to include a control group?

Accepted Answer

To compare the effects of the drug against a group that does not receive it.

Question 19

Which of the following equations best represents the concept of dynamic equilibrium in homeostasis?

Accepted Answer

$$	ext{Set Point} \pm 	ext{Normal Range}$$

Question 20

Which of the following best describes the role of gradients in physiological processes?

Accepted Answer

Gradients drive the movement of matter and energy, such as ions, heat, and chemicals, from areas of higher to lower concentration or pressure.
