1. What is the primary function of the skeletal system?

• A. To produce blood cells
• B. To protect organs
• C. To store fat
• D. To secrete hormones

Correct answer: B

Rationale: The primary function of the skeletal system is to protect vital organs, provide structural support, and enable movement. It serves as a framework that supports and protects internal organs, such as the brain, heart, and lungs. Choice A is incorrect because blood cell production primarily occurs in the bone marrow, a component of the skeletal system but not its primary function. Choice C is incorrect because fat storage is not a primary function of the skeletal system. Choice D is incorrect because hormone secretion is mainly regulated by endocrine glands, not the skeletal system.

2. The spleen is part of which system?

• A. nervous system
• B. integumentary system
• C. lymphatic system
• D. urinary system

Correct answer: C

Rationale: The correct answer is C: lymphatic system. The spleen is a vital organ in the lymphatic system, responsible for filtering blood, producing and storing white blood cells, and aiding the body in fighting infections. The lymphatic system is crucial for maintaining the body's immune defenses and fluid balance. Choices A, B, and D are incorrect because the spleen is not part of the nervous system, integumentary system, or urinary system.

3. Change 0.004 to a ratio.

• A. 1:250
• B. 17:40
• C. 9:20
• D. 20:40

Correct answer: A

Rationale: To convert 0.004 to a ratio, first express it as a fraction. 0.004 = 4/1000 = 1/250. Therefore, the ratio is 1:250. Choice A is the correct answer. Choices B, C, and D are incorrect ratios as they do not represent the equivalent fraction of 0.004.

4. Another word for SITE is?

• A. Severity
• B. Location
• C. Fortunate
• D. Appearance

Correct answer: B

Rationale: Another word for 'SITE' is 'Location.' In this context, 'site' typically refers to a place or area, making 'Location' the most appropriate synonym among the given choices. Choice A, 'Severity,' does not relate to the meaning of 'site' as a place or area. Choice C, 'Fortunate,' and Choice D, 'Appearance,' are also unrelated to the concept of 'site,' making them incorrect choices.

5. Which of the following numbers is a perfect square?

• A. 10
• B. 12
• C. 15
• D. 16

Correct answer: D

Rationale: A perfect square is a number obtained by squaring an integer. In this case, 16 is a perfect square because it is the result of squaring 4 (4 x 4 = 16). The other answer choices, 10, 12, and 15, are not the product of squaring any whole number, making them incorrect. Therefore, the correct answer is 16, as it is a perfect square.
