1. Which hormone is involved in the regulation of water balance in the body?

• A. ADH
• B. Insulin
• C. Cortisol
• D. Thyroxine

Correct answer: A

Rationale: The correct answer is ADH (antidiuretic hormone), also known as vasopressin. ADH helps regulate water balance in the body by controlling the amount of water reabsorbed by the kidneys. When there is a need to conserve water, ADH levels increase, leading to more water reabsorption and concentration of urine. Insulin is involved in regulating blood sugar levels, not water balance. Cortisol is a stress hormone that helps regulate metabolism and immune response, not water balance. Thyroxine is a thyroid hormone that regulates metabolism, growth, and development, not water balance.

2. Change 0.26 to a fraction.

• A. 7/8
• B. 13/50
• C. 26/100
• D. 1/3

Correct answer: B

Rationale: To convert a decimal to a fraction, the decimal is written without the decimal point as the numerator. For 0.26, this gives 26. The denominator is based on the place value of the decimal, which is the number of decimal places the decimal has. In this case, 0.26 has two decimal places, so the fraction is 26/100, which simplifies to 13/50. Choice A (7/8) is incorrect as it does not represent 0.26. Choice C (26/100) is also incorrect because it is not in its simplest form. Choice D (1/3) is incorrect as it is not the correct equivalent fraction for 0.26.

3. Which of the following statements is an opinion related to Super Foods?

• A. Walnuts contain omega-3 fatty acids.
• B. Lentils are high in both protein and fiber.
• C. Pomegranates are delicious and healthful.
• D. Oats move slowly through the digestive tract.

Correct answer: C

Rationale: The statement about pomegranates being delicious and healthful reflects a subjective opinion about taste and health benefits. This contrasts with the other options, which present factual information about the nutritional content of walnuts, lentils, and oats, making C the correct choice for an opinion.

4. Which vitamin is essential for calcium absorption?

• A. Vitamin A
• B. Vitamin D
• C. Vitamin K
• D. Vitamin C

Correct answer: B

Rationale: Vitamin D is crucial for the absorption of calcium in the intestines. It aids in maintaining optimal calcium levels in the body, promoting strong bones and teeth. Without sufficient Vitamin D, the absorption of calcium can be compromised, leading to potential issues with bone health. Choices A, C, and D are incorrect. Vitamin A is essential for vision, skin health, and immune function. Vitamin K is necessary for blood clotting and bone metabolism. Vitamin C is important for collagen synthesis, wound healing, and immune function, but it is not directly involved in calcium absorption.

5. Something that is systematic is organized and planned. Another word for this might be ___________.

• A. involuntary
• B. universal
• C. formulaic
• D. manual

Correct answer: C

Rationale: The word 'formulaic' means following a formula or set pattern. Therefore, something that is systematic and follows a structured plan can also be described as formulaic. Choices A, B, and D are incorrect. 'Involuntary' means done without will or conscious control, 'universal' means affecting, or done by all people or things in the world, and 'manual' means operated or done by hand rather than automatically or electronically. Therefore, 'formulaic' is the most accurate synonym in the given context.
