1. What is the function of the pituitary gland?

Correct answer: A

Rationale: The pituitary gland is often referred to as the "master gland" because it controls the activity of many other endocrine glands in the body. It is located at the base of the brain and produces a variety of hormones that regulate various bodily functions, including growth, metabolism, reproduction, and blood pressure.

2. If the mass of an object remains constant and its velocity doubles, how does its momentum change?

Correct answer: a

Rationale: Momentum is directly proportional to velocity when mass is constant.

3. Edema is a condition characterized by swelling caused by a buildup of lymph fluid. What factors can contribute to edema?

Correct answer: C

Rationale: Edema is a condition where there is an abnormal accumulation of fluid in the body tissues, leading to swelling. Poor circulation or blockage in the lymphatic system can contribute to edema by hindering the proper drainage of lymph fluid. When the lymphatic system is not functioning efficiently, it can result in fluid retention and swelling in the affected areas. Regular exercise and maintaining a healthy weight can actually help improve circulation and lymphatic flow, reducing the risk of edema. Proper hydration is important for overall health but specifically does not directly contribute to the development of edema as poor circulation or lymphatic blockages do.

4. How many moles of oxygen are required to completely react with 5 moles of propane (C3H8) in the combustion reaction?

Correct answer: b

Rationale: The balanced equation is C3H8 + 5O2 → 3CO2 + 4H2O, indicating a 5:10 ratio between moles of oxygen and moles of propane.

5. How does friction affect motion?

Correct answer: b

Rationale: Friction opposes motion, leading to a decrease in speed or hindering movement.
