1. Carbohydrates are composed of a combination of carbon, hydrogen, and which other element?

• A. oxygen.
• B. nitrogen.
• C. water.
• D. glucose.

Correct answer: A

Rationale: Carbohydrates are composed of carbon, hydrogen, and oxygen. These three elements combine to form the basic structure of carbohydrates. Oxygen is an essential element in carbohydrates, contributing to their chemical composition. Choice B (nitrogen) is incorrect as nitrogen is not a typical component of carbohydrates. Choice C (water) is incorrect as water is not an element but a compound composed of hydrogen and oxygen. Choice D (glucose) is incorrect as glucose is a specific type of sugar, not an element found in the composition of carbohydrates.

2. What are the actions involved in the process of digestion?

• A. thermal and chemical.
• B. chemical and segmental.
• C. muscular and chemical.
• D. mechanical and thermal.

Correct answer: C

Rationale: The correct answer is C: 'muscular and chemical.' In the process of digestion, muscular movements help in mixing and propelling food along the digestive tract, while chemical breakdowns involving enzymes and acids break down food into smaller molecules for absorption. Choices A, B, and D are incorrect as thermal, segmental, and mechanical actions are not the primary actions involved in the digestion process.

3. A food choice equivalent to one serving from the Protein group of MyPlate is:

• A. 1 tbsp peanut butter.
• B. 3 oz fish.
• C. 2 oz cheese.
• D. 1/2 cup cooked dry beans or peas.

Correct answer: A

Rationale: One tablespoon of peanut butter is equivalent to one serving from the Protein group in MyPlate. It provides a good amount of protein and healthy fats. Choices B, C, and D are incorrect as they represent larger serving sizes than a single serving from the Protein group in MyPlate. 3 oz of fish, 2 oz of cheese, and 1/2 cup of cooked dry beans or peas would exceed the recommended serving size for the Protein group.

4. The process of photosynthesis is responsible for the synthesis of:

• A. carbohydrates.
• B. proteins.
• C. fats.
• D. vitamins.

Correct answer: A

Rationale: The correct answer is A: carbohydrates. Photosynthesis is the process by which plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose (a type of carbohydrate). This glucose is used by the organisms for energy production and as a building block for other organic compounds. Choice B, proteins, is incorrect because proteins are synthesized through a different process involving amino acids. Choice C, fats, are not directly synthesized through photosynthesis; they are typically formed from excess carbohydrates. Choice D, vitamins, are organic compounds that are required in small amounts for various physiological functions but are not directly synthesized through photosynthesis.

5. Which hormone stimulates the gallbladder to contract?

• A. Secretin.
• B. Cholecystokinin (CCK).
• C. Gastrin.
• D. Gastric inhibitory polypeptide (GIP).

Correct answer: B

Rationale: Cholecystokinin (CCK) is the hormone responsible for stimulating the gallbladder to contract and release bile into the small intestine. Secretin primarily acts on the pancreas to stimulate the secretion of bicarbonate-rich fluid. Gastrin functions in the stimulation of gastric acid secretion, while Gastric inhibitory polypeptide (GIP) plays a role in inhibiting gastric acid secretion and stimulating insulin release.
