1. Which one is not a reactant in photosynthesis?

• A. Water
• B. Light energy
• C. Glucose
• D. Carbon dioxide

Correct answer: C

Rationale: The correct answer is C: Glucose. Glucose is not a reactant in photosynthesis but a product. During photosynthesis, plants use water, carbon dioxide, and light energy as reactants to produce glucose and oxygen. Water is essential for the process of photosynthesis, along with carbon dioxide and light energy. Light energy is necessary for the light-dependent reactions to occur, which eventually leads to the production of glucose. Carbon dioxide is absorbed by plants through tiny pores called stomata and is used in the Calvin cycle to synthesize glucose. Therefore, glucose is the product of photosynthesis, not a reactant.

2. If a patient has SALLOW skin, what is true?

• A. Her skin has a yellow tint
• B. Her skin has a blue tint
• C. Her skin has a red tint
• D. Her skin has a green tint

Correct answer: A

Rationale: Sallow skin is a term used to describe skin that appears yellowish in color. This discoloration can be due to various factors, such as an underlying health condition, poor circulation, or certain medications. Observing sallow skin can be an important clinical indicator that prompts further investigation into the patient's overall health status. Choice B, blue tint, is incorrect as sallow skin is not associated with a blue color. Choice C, red tint, and Choice D, green tint, are also incorrect as sallow skin specifically refers to a yellowish complexion, not red or green.

3. Which mineral supports the function of the thyroid?

• A. Manganese
• B. Iodine
• C. Phosphorus
• D. Zinc

Correct answer: B

Rationale: Iodine is the mineral that supports the function of the thyroid. The thyroid gland requires iodine to produce thyroid hormones, which are essential for regulating metabolism and other important bodily functions. A deficiency in iodine can lead to thyroid disorders such as hypothyroidism or goiter. Manganese (Choice A), Phosphorus (Choice C), and Zinc (Choice D) do not play a direct role in supporting the thyroid function like iodine does. While these minerals are important for various bodily functions, they are not specifically required for the thyroid gland's hormone production.

4. What is another name for the light-independent reaction in plants?

• A. Photosynthesis
• B. Calvin cycle
• C. Germination
• D. Phosphorus cycle

Correct answer: B

Rationale: The light-independent reaction in plants is also known as the Calvin cycle. This biochemical pathway, named after Melvin Calvin who discovered it, takes place in the stroma of chloroplasts and is responsible for converting carbon dioxide into glucose using ATP and NADPH generated during the light-dependent reactions of photosynthesis. The Calvin cycle does not directly require light to function, hence the alternative name as the light-independent reaction. Choices A, C, and D are incorrect. Photosynthesis is the overall process of converting light energy into chemical energy, which includes both light-dependent and light-independent reactions. Germination is the process where a seed sprouts into a new plant. The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.

5. What is the author’s primary purpose in writing the essay about High Fructose Corn Syrup?

• A. To inform.
• B. To persuade.
• C. To entertain.
• D. To analyze.

Correct answer: A

Rationale: The correct answer is A: 'To inform.' The essay provides detailed information about High Fructose Corn Syrup (HFCS), discussing its impact on health, how it is derived, its link to health issues like obesity, and the ongoing debates surrounding its consumption and health implications. The primary goal of the author is to educate the readers about HFCS and its effects, rather than persuade them to take a particular stance (choice B), entertain them (choice C), or analyze the topic in depth (choice D). The essay presents facts, studies, and expert opinions to inform the audience about the controversies and health risks associated with HFCS consumption, aiming to enhance the readers' knowledge and understanding of this sweetener's implications on health.
