1. Which mineral helps maintain fluid balance in the body?

• A. Potassium
• B. Cobalt
• C. Chromium
• D. Sulfur

Correct answer: A

Rationale: Potassium is the mineral that helps maintain fluid balance in the body. It plays a crucial role in regulating the amount of fluid inside and outside the body's cells, thereby helping to maintain proper hydration levels. Potassium works in conjunction with sodium to regulate fluid balance and is essential for proper muscle function, nerve transmission, and heart health. Cobalt, chromium, and sulfur do not play significant roles in maintaining fluid balance in the body, making them incorrect choices for this question.

2. What does 'overt' mean?

• A. Hidden
• B. Obvious or easily observed
• C. Barely noticeable
• D. Misleading

Correct answer: B

Rationale: The correct answer is B: 'Obvious or easily observed.' Overt means something that is not hidden or concealed but rather openly displayed or easily noticed. Choice A, 'Hidden,' is the opposite of overt. Choice C, 'Barely noticeable,' implies something not overt but rather subtle. Choice D, 'Misleading,' is unrelated to the definition of overt.

3. The anterior chamber of the eye lies between the ___________.

• A. iris and lens
• B. lens and retina
• C. cornea and iris
• D. retina and optic nerve

Correct answer: A

Rationale: The anterior chamber of the eye is the fluid-filled space located between the cornea and the iris in the front part of the eye. It contains aqueous humor and helps maintain intraocular pressure. The space between the iris and the lens is known as the anterior chamber, making option A, 'iris and lens,' the correct choice. Options B, C, and D are incorrect because they do not describe the correct anatomical location of the anterior chamber.

4. What is the primary function of the large intestine?

• A. To absorb water and form solid waste
• B. To produce digestive enzymes
• C. To secrete hormones
• D. To transport nutrients

Correct answer: A

Rationale: The correct answer is A. The primary function of the large intestine is to absorb water from the remaining indigestible food matter and form solid waste (feces) for excretion. This process helps in reabsorbing water and electrolytes, resulting in the formation of feces by compacting the waste material. Choices B, C, and D are incorrect because the large intestine is not responsible for producing digestive enzymes, secreting hormones, or transporting nutrients. These functions are typically associated with other parts of the digestive system.

5. What does Redundancy mean?

• A. Deficiency
• B. Surplus
• C. Delicate
• D. Abundance

Correct answer: B

Rationale: Redundancy means having more than is needed, making 'Surplus' the correct choice. The term does not relate to 'Deficiency' (lack), 'Delicate' (fragile), or 'Abundance' (plenty). In the context of this question, Redundancy refers to an excess or surplus of something.
