1. What is the number of students who said their favorite color is blue if 35% of 100 students chose blue as their favorite color?

• A. 35
• B. 25
• C. 20
• D. 10

Correct answer: A

Rationale: To find the number of students who said their favorite color is blue, we calculate 35% of 100, which is (35/100) * 100 = 35. Therefore, 35 students said their favorite color is blue. Choice B is incorrect because it represents the percentage of students who chose red. Choice C is incorrect as it represents the percentage of students who chose green. Choice D is incorrect as it represents the percentage of students who chose yellow.

2. Which of the following statements is correct based on anatomical terms?

• A. The shoulder joint is proximal to the neck.
• B. The elbow joint is superior to the shoulder.
• C. The thoracic vertebrae are superior to the cervical vertebrae.
• D. The thumb is on the lateral aspect of the hand.

Correct answer: D

Rationale: Option D is the correct answer based on anatomical terms. The thumb is indeed located on the lateral aspect of the hand, following anatomical positioning. The terms 'proximal,' 'superior,' and 'inferior' are used in relation to the center of the body or a specific point of reference, while 'lateral' and 'medial' describe positions further away or closer to the midline of the body. Therefore, the thumb being on the lateral side of the hand is an accurate anatomical description. Choices A, B, and C are incorrect because they do not align with anatomical terminology. In anatomical terms, 'proximal' refers to a position closer to the center of the body, 'superior' indicates a position above or higher than another part, and 'inferior' signifies a position below or lower than another part. The shoulder joint is distal to the neck, the elbow is inferior to the shoulder, and the cervical vertebrae are superior to the thoracic vertebrae.

3. Which of the following correctly matches a category of protein with a physiological example?

• A. Keratin is a structural protein
• B. Antigens are hormonal proteins
• C. Channel proteins are marker proteins
• D. Actin is a transport protein

Correct answer: A

Rationale: Keratin is indeed a type of structural protein found in the skin, hair, and nails of animals. It provides strength and protection, helping to maintain the overall structure of these tissues. The other choices are incorrect as antigens are not hormonal proteins but rather are involved in immune response, channel proteins are involved in facilitating the transport of ions or molecules across cell membranes, and actin is primarily involved in cell structure and movement, not as a transport protein.

4. What is the function of the adrenal glands?

• A. To regulate metabolism
• B. To produce bile
• C. To produce red blood cells
• D. To regulate blood glucose

Correct answer: D

Rationale: The correct answer is D: To regulate blood glucose. The adrenal glands play a crucial role in regulating blood glucose levels and the body's response to stress. Choice A, 'To regulate metabolism,' is incorrect as the primary role of the adrenal glands is not directly related to metabolism regulation. Choice B, 'To produce bile,' is incorrect because bile is produced by the liver, not the adrenal glands. Choice C, 'To produce red blood cells,' is also incorrect as the production of red blood cells primarily occurs in the bone marrow, not the adrenal glands.

5. Which of the following sentences correctly uses a semicolon?

• A. I have a big test tomorrow; I can't go out tonight.
• B. I have a big test tomorrow; I can't go out tonight.
• C. I have a big test tomorrow; and I can't go out tonight.
• D. I have a big test tomorrow; but I can't go out tonight.

Correct answer: A

Rationale: The correct use of a semicolon is to join two closely related independent clauses. Choice A is the only option that correctly uses a semicolon to connect two independent clauses: 'I have a big test tomorrow' and 'I can't go out tonight.' Choice B incorrectly uses a comma instead of a semicolon. Choice C adds an unnecessary 'and' after the semicolon, which disrupts the correct punctuation usage. Choice D introduces a contradictory conjunction 'but' after the semicolon, which is not necessary for the given context. Therefore, the correct answer is A.
