1. A dietitian wants to convince a patient to lose weight. Which statement below best communicates a scientific argument that justifies the need for weight loss?

• A. Losing weight can lower blood pressure, increase energy levels, and promote overall health.
• B. Society tends to treat overweight people unfairly.
• C. Members of the opposite sex are more interested in people who maintain a healthy weight.
• D. Losing weight is easy to do.

Correct answer: A

Rationale: Choice A is the correct answer as it provides a scientific argument supported by evidence. Losing weight has been shown to lower blood pressure, increase energy levels, and promote overall health. These are concrete health benefits that can be objectively measured and monitored. Choices B and C do not offer scientific justifications for weight loss but rather focus on societal perceptions and personal relationships. Choice D is incorrect as losing weight is not always easy and may require significant effort and lifestyle changes.

2. Which of the following organs does not belong with the others?

• A. Thyroid gland
• B. Stomach
• C. Intestines
• D. Pancreas

Correct answer: B

Rationale: The correct answer is B - Stomach. The stomach is primarily involved in the digestive system, breaking down food through digestion. In contrast, the thyroid gland, intestines, and pancreas are part of the endocrine system or digestive system, involved in hormone production, nutrient absorption, and digestion. Therefore, the stomach stands out as the odd one in this group as it is the only organ specifically dedicated to digestion, while the others have dual roles or different primary functions.

3. What is the waste product of protein digestion?

• A. Glucose
• B. Amino acids
• C. Fatty acids
• D. Ammonia

Correct answer: D

Rationale: The waste product of protein digestion is ammonia. Protein digestion breaks down proteins into amino acids, and during this process, ammonia is produced. Ammonia is toxic and needs to be converted into urea in the liver for excretion via urine. Glucose is a product of carbohydrate digestion, amino acids are building blocks of proteins, and fatty acids are the end products of fat digestion. Therefore, the correct answer is ammonia.

4. What is the unit of force in the SI system?

• A. Newton (N)
• B. Kilogram (kg)
• C. Meter (m)
• D. Second (s)

Correct answer: A

Rationale: The unit of force in the SI system is the Newton (N). It is defined as the amount of force required to accelerate a mass of one kilogram at a rate of one meter per second squared. In the SI system, force is measured in Newtons, not in kilograms, meters, or seconds. Choice B, Kilogram (kg), is incorrect because kilograms are units of mass, not force. Choice C, Meter (m), is incorrect because meters are units of length, not force. Choice D, Second (s), is incorrect because seconds are units of time, not force.

5. Water is considered a universal solvent due to its ____.

• A. Cohesion
• B. Adhesion
• C. Molarity
• D. Dilution

Correct answer: B

Rationale: The correct answer is B: Adhesion. Water's polarity allows it to dissolve many substances due to its ability to adhere to and interact with other molecules, making it an effective solvent. Cohesion refers to water molecules sticking together, molarity is a measure of concentration, and dilution refers to the process of reducing the concentration of a solute in a solution, none of which directly relate to water's role as a universal solvent.
