1. The hypodermis is primarily composed of which tissue?

• A. Adipose
• B. Connective
• C. Epithelial
• D. Muscle

Correct answer: A

Rationale: The hypodermis, also known as the subcutaneous layer, is primarily composed of adipose (fat) tissue. Adipose tissue in the hypodermis serves as an insulator, energy reserve, and cushioning for the body. Choice B, Connective tissue, is a broad category that includes various types of tissue like adipose, but the hypodermis is specifically rich in adipose tissue. Choice C, Epithelial tissue, is not the primary component of the hypodermis; it is mainly found covering body surfaces and lining cavities. Choice D, Muscle tissue, is not a major component of the hypodermis; muscle tissue is mainly located deeper in the body and serves in movement and support functions.

2. What are glands that release hormones directly into the bloodstream without ducts called?

• A. Exocrine glands
• B. Endocrine glands
• C. Apocrine glands
• D. Merocrine glands

Correct answer: B

Rationale: Endocrine glands release hormones directly into the bloodstream without the use of ducts. This allows the hormones to be distributed throughout the body to target organs or tissues. Exocrine glands, on the contrary, release their secretions through ducts to the external environment or onto a surface, such as sweat glands. Apocrine and merocrine glands are both types of exocrine glands that release their secretions through different mechanisms. Apocrine glands release their secretions along with portions of the cell itself, while merocrine glands release their secretions through exocytosis without loss of cellular material.

3. What is the author’s tone in the passage?

• A. The author’s tone is optimistic.
• B. The author’s tone is pessimistic.
• C. The author’s tone is matter-of-fact.
• D. The author’s tone is angry.

Correct answer: C

Rationale: The author's tone in the passage is matter-of-fact. The text provides practical suggestions and advice in a straightforward manner, focusing on actions without expressing emotions or bias. Choices A, B, and D are incorrect because the author does not show signs of being optimistic, pessimistic, or angry; instead, the author presents information objectively and neutrally.

4. Where does the digestion of food start?

• A. Esophagus
• B. Stomach
• C. Small intestine
• D. Mouth

Correct answer: D

Rationale: The correct answer is the mouth. Digestion begins in the mouth where mechanical breakdown occurs through chewing, and chemical breakdown begins with saliva. Enzymes in saliva start breaking down carbohydrates, initiating the digestion process. The esophagus is responsible for transporting food from the mouth to the stomach and does not play a role in the digestion process. The stomach continues the digestion process after the food leaves the mouth. The small intestine is primarily responsible for absorbing nutrients from the digested food, rather than being the initial site of digestion.

5. Caret, carrot, and to, two, and too share something in common. They:

• A. Are nouns
• B. Are monosyllabic
• C. Are homophones
• D. Represent things in nature

Correct answer: C

Rationale: The correct answer is C. Caret, carrot, and to, two, and too are all examples of homophones. Homophones are words that sound alike but have different meanings and spellings. In this case, while these words are spelled differently and have different meanings, they are pronounced the same way. Choices A, B, and D are incorrect because these words being discussed do not all fall under the same grammatical category as nouns, monosyllabic words, or representations of things in nature. The commonality among these words lies in being homophones, not in being nouns, monosyllabic, or representations of nature.
