1. What part of speech is the word 'growing' in the sentence: 'He felt a growing sense of unease'?

• A. Verb
• B. Adjective
• C. Noun
• D. Adverb

Correct answer: B

Rationale: The word 'growing' in the sentence 'He felt a growing sense of unease' is functioning as an adjective. It describes the sense of unease, indicating a characteristic of the sense rather than an action (verb), a person, place, thing, or idea (noun), or modifying a verb, an adjective, or another adverb (adverb). Therefore, 'growing' is an adjective in this context.

2. Which blood component is chiefly responsible for clotting?

• A. Platelets
• B. Red blood cells
• C. Antigens
• D. Plasma cells

Correct answer: A

Rationale: The correct answer is A: Platelets. Platelets are small cell fragments in the blood that play a crucial role in clotting. When there is an injury, platelets adhere to the site and release chemicals that help form a clot to prevent excessive bleeding. Red blood cells transport oxygen, antigens are substances that trigger an immune response, and plasma cells are a type of white blood cell involved in producing antibodies, none of which are primarily responsible for clotting.

3. What is the process of removing waste products from the cell called?

• A. Exocytosis
• B. Endocytosis
• C. Phagocytosis
• D. Pinocytosis

Correct answer: A

Rationale: A) Exocytosis is the process by which cells expel waste products or other substances by fusing a vesicle containing the waste with the cell membrane, releasing its contents outside the cell. This process is essential for maintaining cellular homeostasis by removing waste products from the cell. B) Endocytosis is the process by which cells take in substances by engulfing them in a vesicle formed from the cell membrane. This process is the opposite of exocytosis and is used to bring substances into the cell. C) Phagocytosis is a type of endocytosis where cells engulf solid particles or other cells to form a vesicle called a phagosome. This process is used by immune cells to engulf and destroy pathogens. D) Pinocytosis is a type of endocytosis where cells engulf fluids and dissolved solutes. This process allows cells to take in nutrients.

4. Which of these descriptions provides the most detailed and objective support for the claim that drinking and driving is unsafe?

• A. A dramatized television commercial reenacting a fatal accident.
• B. The Department of Transportation's press release noting the deployment of additional patrol units.
• C. Congressional written testimony on drinking incidents.
• D. A highway bulletin warning of penalties for drinking and driving.

Correct answer: C

Rationale: Congressional written testimony on drinking incidents provides the most detailed and factual data on the subject, making it the most objective support for the claim that drinking and driving is unsafe. Choice A, the dramatized television commercial, may be emotionally impactful but lacks detailed data. Choice B, the Department of Transportation's press release, focuses on enforcement actions rather than detailed information on the dangers. Choice D, the highway bulletin warning of penalties, emphasizes consequences rather than providing detailed support for the claim.

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.
