Anatomy

1. What is the difference between exhalation (expiration) and inhalation (inspiration)?

Correct answer: B

Rationale: Option B is the correct answer because inhalation is the process of breathing in, where the diaphragm and intercostal muscles contract to expand the chest cavity, allowing air to enter the lungs. This air is rich in oxygen, which is essential for cellular respiration. On the other hand, exhalation is the process of breathing out, where the diaphragm and intercostal muscles relax, causing the chest cavity to decrease in size and air to be expelled from the lungs. This air is depleted of oxygen as it has been used up during cellular respiration. Understanding the difference between inhaling oxygen-rich air and exhaling oxygen-depleted air is crucial for comprehending the respiratory system's function and the exchange of gases in the body.

2. What is the difference between the atomic number and the mass number of an atom?

Correct answer: C

Rationale: The atomic number and the mass number are two fundamental properties of an atom. They provide important information about the identity and structure of an element.

3. What is the main function of estuaries?

Correct answer: B

Rationale: Rationale: Estuaries are coastal areas where freshwater from rivers and streams mixes with saltwater from the ocean. They serve as important habitats for a variety of marine life, including fish, birds, and other wildlife. Estuaries provide shelter, breeding grounds, and food sources for many species, making them crucial for the overall health of marine ecosystems. While estuaries can help filter pollutants to some extent, their primary function is to support and sustain diverse populations of plants and animals. Storing carbon dioxide and generating wind power are not main functions of estuaries.

4. The kidneys are bean-shaped organs that perform several vital functions. Which of the following is NOT a primary function of the kidneys?

Correct answer: C

Rationale: The correct answer is C. While the kidneys perform multiple vital functions, such as filtering waste products from the blood, regulating blood pressure, and maintaining water balance in the body, they do not produce red blood cells. Red blood cell production occurs in the bone marrow, specifically in the spongy tissue called the red bone marrow. Therefore, the kidneys' primary functions do not include producing red blood cells.

5. A person throws a ball horizontally. What force changes the direction of the ball's motion?

Correct answer: B

Rationale: When a person throws a ball horizontally, the initial force that propels the ball forward is the force of throwing (A). However, the force that changes the direction of the ball's motion is the gravitational force (B), which acts vertically downward and causes the ball to follow a curved path. Air resistance (C) and normal force from the ground (D) do not directly change the direction of the ball's motion in this scenario.

6. A population refers to a group of organisms of the same:

Correct answer: A

Rationale: In ecology, a population is a specific group of organisms of the same species living in a particular geographic area at a given time. They share a common gene pool and interact with each other and their environment.
