1. Select the noun that the underlined adjectives describe: 'Two weeks after his surgery, Henry felt strong and healthy.'

• A. weeks
• B. his
• C. surgery
• D. Henry

Correct answer: D

Rationale: The correct answer is D (Henry) because the adjectives 'strong and healthy' describe 'Henry.' In this sentence, 'Henry' is the subject being described as strong and healthy, not 'weeks,' 'his,' or 'surgery.' While 'weeks' and 'surgery' are nouns mentioned in the sentence, they are not the nouns being described by the adjectives in question. 'His' is a possessive pronoun referring to Henry and does not match the criteria of being directly described by the adjectives 'strong and healthy.' Therefore, 'Henry' is the noun that the adjectives specifically describe in this context.

2. The pancreas releases a number of digestive enzymes into the small intestine. Which of the following enzymes is NOT produced by the pancreas?

• A. Trypsin (protein digestion)
• B. Amylase (carbohydrate digestion)
• C. Lipase (fat digestion)
• D. Lactase (sugar digestion)

Correct answer: D

Rationale: Lactase is an enzyme responsible for breaking down lactose, a sugar found in dairy products, and it is produced by the small intestine, not the pancreas. The pancreas produces enzymes like trypsin for protein digestion, amylase for carbohydrate digestion, and lipase for fat digestion. Therefore, the correct answer is D. Choices A, B, and C are incorrect because trypsin, amylase, and lipase are indeed enzymes produced by the pancreas for the digestion of proteins, carbohydrates, and fats, respectively.

3. Which layer of the skin, containing connective tissue, blood vessels, and nerve endings, is located beneath the epidermis?

• A. Epidermis
• B. Dermis
• C. Hypodermis
• D. Stratum corneum

Correct answer: B

Rationale: The correct answer is the dermis. The dermis is the deeper layer of the skin that contains connective tissue, blood vessels, and nerve endings. It is located beneath the epidermis and provides structural support, nourishment, and sensitivity to the skin. The epidermis is the outermost layer of the skin responsible for protection. The hypodermis, also known as the subcutaneous layer, is the deepest layer that contains fat cells and plays a role in insulation and energy storage. The stratum corneum is the outermost layer of the epidermis composed of dead skin cells that are continually shed and replaced.

4. When a biologist describes the physical and visible expression of a genetic trait, which of the following is being referred to?

• A. Phenotype
• B. Allele
• C. Gamete
• D. Genotype

Correct answer: A

Rationale: The correct answer is A: Phenotype. Phenotype specifically refers to the observable physical characteristics resulting from the interaction of an individual's genetic makeup (genotype) with environmental influences. It represents the outward expression of an organism's genetic makeup. Allele, represented by choice B, refers to different forms of a gene and is not the visible expression of a trait. Gamete, represented by choice C, is a reproductive cell and not directly related to the physical expression of traits. Genotype, represented by choice D, refers to the genetic makeup of an organism and is distinct from the observable physical characteristics denoted by phenotype.

5. Which of the following types of muscle tissue is found attached to bones and allows for voluntary movement?

• A. Smooth muscle
• B. Cardiac muscle
• C. Skeletal muscle
• D. Connective tissue

Correct answer: C

Rationale: The correct answer is C: Skeletal muscle. Skeletal muscle is attached to bones and allows for voluntary movement, such as walking, running, and lifting objects. Smooth muscle, found in the walls of internal organs and blood vessels, is responsible for involuntary movements. Cardiac muscle is specific to the heart and controls involuntary contraction. Connective tissue, on the other hand, provides support and connects different structures in the body, but it is not responsible for voluntary movement like skeletal muscle.
