1. Which of the following correctly lists the normal blood flow through the heart?

Correct answer: B

Rationale: The correct order of normal blood flow through the heart is as follows: from the body, blood flows into the right atrium, then to the right ventricle, followed by the lungs through the pulmonary artery for oxygenation. Oxygenated blood then returns to the heart through the pulmonary veins into the left atrium, then moves into the left ventricle before being pumped out to the body. Choice B correctly depicts this sequential flow of blood through the heart. Choices A, C, and D are incorrect as they do not follow the typical path of blood flow through the heart.

2. When 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). Gravitational force acts vertically downward, causing 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.

3. What is the term for a solution that contains the maximum amount of solute that can dissolve at a specific temperature and pressure?

Correct answer: A

Rationale: A saturated solution is defined as a solution that has dissolved the maximum amount of solute possible at a specific temperature and pressure. In a saturated solution, any additional solute added will not dissolve, resulting in a visible precipitate. Choice B, unsaturated solution, refers to a solution where more solute can still be dissolved. Choices C and D, dilute solution and concentrated solution, do not specifically refer to the maximum amount of solute that can be dissolved at a given temperature and pressure, making them incorrect in this context.

4. Which of the following types of muscle tissue is found attached to bones and allows for voluntary movement?

Correct answer: C

Rationale: The correct answer is C: Skeletal muscle. Skeletal muscle is attached to bones and allows for voluntary movement, such as walking, running, and lifting objects. Smooth muscle, found in the walls of internal organs and blood vessels, is responsible for involuntary movements. Cardiac muscle is specific to the heart and controls involuntary contraction. Connective tissue, on the other hand, provides support and connects different structures in the body, but it is not responsible for voluntary movement like skeletal muscle.

5. Which of the following is a genetic condition that affects the respiratory system?

Correct answer: B

Rationale: The correct answer is B, Cystic fibrosis. Cystic fibrosis is a genetic disorder that primarily affects the respiratory and digestive systems. It leads to the production of thick mucus in the lungs, causing breathing difficulties and increasing the risk of respiratory infections. Choice A, Asthma, is a chronic respiratory condition characterized by inflammation and narrowing of the airways, but it is not a genetic condition. Choice C, Mycosis, refers to fungal infections and is not a genetic condition specifically affecting the respiratory system. Choice D, Surfactant Deficiency, is a condition related to respiratory distress syndrome in newborns and is not a genetic disorder affecting the respiratory system in general.
