1. What is the unit of measurement for power?

• A. Joule (J)
• B. Newton (N)
• C. Watt (W)
• D. Kilogram-meter (kg·m)

Correct answer: c

Rationale: Power is measured in watts (W) in the SI unit system.

2. The gland located on top of the kidneys responsible for regulating blood pressure and electrolyte balance is the:

• A. Thyroid gland
• B. Pituitary gland
• C. Adrenal gland
• D. Parathyroid gland

Correct answer: D

Rationale: The correct answer is C: Adrenal gland. The adrenal glands are located on top of the kidneys and play a crucial role in regulating blood pressure and electrolyte balance by secreting hormones such as aldosterone and cortisol. The thyroid gland (A) regulates metabolism, the pituitary gland (B) controls other endocrine glands, and the parathyroid gland (D) regulates calcium levels in the blood. Therefore, the adrenal gland is specifically responsible for the functions mentioned in the question, making it the correct choice.

3. The framework of bones, cartilage, ligaments, and tendons that provides structure, support, and facilitates movement is the:

• A. Muscular system
• B. Skeletal system
• C. Nervous system
• D. Endocrine system

Correct answer: B

Rationale: The correct answer is B: Skeletal system. The skeletal system is composed of bones, cartilage, ligaments, and tendons that work together to provide structure, support, and facilitate movement in the body. The bones serve as the framework that supports and protects the body's organs, while cartilage cushions the joints. Ligaments connect bones to each other, and tendons connect muscles to bones, allowing for movement. The muscular system (choice A) consists of muscles that work with the skeletal system to produce movement. The nervous system (choice C) controls and coordinates bodily functions through the brain, spinal cord, and nerves. The endocrine system (choice D) regulates various bodily functions through the release of hormones. Therefore, the skeletal system is the correct answer as it specifically refers to the framework of bones, cartilage, ligaments, and tendons that support and enable movement in the body.

4. What is the process of breaking down proteins into amino acids called?

• A. Proteolysis
• B. Lipolysis
• C. Carbohydrate catabolism
• D. Nucleic acid catabolism

Correct answer: A

Rationale: Rationale: Proteolysis is the process of breaking down proteins into amino acids. Lipolysis is the breakdown of fats into fatty acids and glycerol, not proteins. Carbohydrate catabolism involves the breakdown of carbohydrates into glucose for energy production. Nucleic acid catabolism is the breakdown of nucleic acids into nucleotides. In this context, the specific process of breaking down proteins into amino acids is best described by proteolysis.

5. A clinic sees an average of 25 patients every 4 hours. If the clinic is open for 8 hours, how many patients will they see in total?

• A. 35
• B. 50
• C. 75
• D. 200

Correct answer: D

Rationale: Rationale: 1. First, determine how many patients the clinic sees in one hour: 25 patients / 4 hours = 6.25 patients per hour (approximately 6 patients per hour) 2. Since the clinic is open for 8 hours, multiply the number of patients seen per hour by the number of hours the clinic is open: 6.25 patients/hour * 8 hours = 50 patients 3. Therefore, the clinic will see a total of 50 patients in 8 hours, which corresponds to answer choice D) 200.

6. Identify the predicate in the following sentence: "The children built a sandcastle on the beach."

• A. on the beach
• B. built a sandcastle
• C. children
• D. the

Correct answer: B

Rationale: The predicate is the verb and any words following it that describe the action or state of being of the subject.
