Accepted Answer

Maintaining boundaries

Question 3

Which organ system is primarily responsible for synthesizing vitamin D and protecting deeper tissues from injury?

Accepted Answer

Integumentary system

Question 4

A person is exposed to a cold environment. Their body responds by shivering to generate heat. Which type of homeostatic control mechanism is this an example of?

Accepted Answer

Negative feedback

Question 5

Which of the following is NOT considered a survival need for humans?

Accepted Answer

High atmospheric pressure

Question 6

Which statement about energy is correct?

Accepted Answer

Energy can be converted from potential to kinetic form.

Question 7

Given the atomic numbers: Hydrogen ($$Z=1$$), Helium ($$Z=2$$), and Lithium ($$Z=3$$), which element has the greatest number of electrons in a neutral atom?

Accepted Answer

Lithium

Question 8

A solution is prepared by dissolving glucose in water. In this mixture, which is the solute and which is the solvent?

Accepted Answer

Glucose is the solute, water is the solvent.

Question 9

Which type of chemical bond is formed by the sharing of two or more valence shell electrons between two atoms?

Accepted Answer

Covalent bond

Question 10

A molecule of water ($$H_2O) is $$described as a polar covalent molecule. What property of the atoms involved leads to this polarity?

Accepted Answer

Oxygen is more electronegative than hydrogen, causing unequal sharing of electrons.

Question 11

Which organ system is responsible for eliminating nitrogenous wastes and regulating water, electrolyte, and acid-base balance of the blood?

Accepted Answer

Urinary system

Question 12

If a cell is placed in a solution and the cell swells due to water entering, what type of solution is it most likely in?

Accepted Answer

Hypotonic

Question 13

Which of the following best describes the role of the receptor in a homeostatic control mechanism?

Accepted Answer

It monitors the environment and responds to changes (stimuli).

Question 14

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

Accepted Answer

Blood clotting cascade

Question 15

A patient is unable to produce insulin, resulting in high blood glucose levels. This is an example of:

Accepted Answer

Homeostatic imbalance

Question 16

Which of the following statements about isotopes is correct?

Accepted Answer

Isotopes have the same number of protons but different numbers of neutrons.

Question 17

Which organ system is responsible for transporting oxygen, carbon dioxide, nutrients, and wastes via blood?

Accepted Answer

Cardiovascular system

Question 18

Which of the following best describes the octet rule?

Accepted Answer

Atoms desire 8 electrons in their valence shell to achieve stability.

Question 19
