1. Based on the affixes, which of the following words could be defined as 'the study of humans'?

• A. Biology
• B. Philanthropy
• C. Anthropomorphism
• D. Anthropology

Correct answer: D

Rationale: The correct answer is 'Anthropology.' This term is derived from the Greek words 'anthropos' meaning 'human' and 'logos' meaning 'study.' Therefore, Anthropology refers to the study of humans. Choice A, 'Biology,' is the study of living organisms, not specifically focused on humans. Choice B, 'Philanthropy,' refers to the practice of giving and helping others. Choice C, 'Anthropomorphism,' is the attribution of human characteristics to non-human entities.

2. When rounding 245.2678 to the nearest thousandth, which place value would be used to decide whether to round up or round down?

• A. Ten-thousandths
• B. Thousandths
• C. Hundredths
• D. Thousand

Correct answer: A

Rationale: When rounding a number to the nearest thousandth, you look at the digit in the ten-thousandths place to determine whether to round up or down the digit in the thousandths place. In this case, rounding 245.2678 to the nearest thousandth, the digit in the ten-thousandths place is 6, which is greater than or equal to 5, so you would round up the digit in the thousandths place. Therefore, the correct answer is the ten-thousandths place. Choices B, C, and D are incorrect because they do not directly influence the rounding of the thousandths place in this scenario.

3. Which of the following hormones would cause skin color to become darker?

• A. Follicle-stimulating
• B. Growth-stimulating
• C. Thyroid-stimulating
• D. Melanocyte-stimulating

Correct answer: D

Rationale: The correct answer is D, Melanocyte-stimulating. Melanocyte-stimulating hormone (MSH) stimulates melanocytes in the skin to produce more melanin, leading to darker skin pigmentation. Choices A, B, and C are incorrect as Follicle-stimulating hormone (FSH) stimulates follicle growth in the reproductive system, Growth-stimulating hormone is a vague term not specific to any known hormone, and Thyroid-stimulating hormone (TSH) stimulates the thyroid gland to produce thyroid hormones, not affecting skin color pigmentation.

4. Which type of blood vessel carries blood away from the heart?

• A. Vein
• B. Artery
• C. Capillary
• D. Venule

Correct answer: B

Rationale: The correct answer is B: Artery. Arteries carry oxygen-rich blood away from the heart to various parts of the body. Veins, on the other hand, carry blood back to the heart. Capillaries are tiny blood vessels where oxygen and nutrients are exchanged with tissues. Venules are small veins that collect blood from capillaries, not from the heart, making them incorrect in this context.

5. Which gland, often referred to as the 'master gland' of the endocrine system and located at the base of the brain, secretes various hormones that control other glands?

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

Correct answer: B

Rationale: The pituitary gland is correctly known as the 'master gland' of the endocrine system. It is situated at the base of the brain and plays a crucial role in secreting a variety of hormones that regulate the functions of other endocrine glands in the body. These hormones control growth, metabolism, reproduction, and various other essential bodily functions. The other choices, thyroid gland, adrenal gland, and pancreas, are incorrect as they do not serve as the 'master gland' of the endocrine system nor are located at the base of the brain like the pituitary gland.
