1. Which of the following is the smallest unit of matter?

• A. Molecule
• B. Atom
• C. Compound
• D. Element

2. A patient needs to take 2 tablets for every 30 pounds of body weight. If they weigh 150 pounds, how many tablets should they take?

• A. 5
• B. 10
• C. 15
• D. 20

Correct answer: A

Rationale: Divide the patient's weight (150 pounds) by the ratio denominator (30 pounds/tablet) to get 5 tablets.

3. A bar graph shows the number of patients admitted to the ER each day for a week. How do you determine the day with the highest number of admissions?

• A. Find the tallest bar in the graph.
• B. Compare the heights of all bars.
• C. Calculate the average number of admissions per day.
• D. Subtract the lowest number of admissions from the highest.

Correct answer: A

Rationale: The best approach is to find the tallest bar

4. The human body's command center, integrating sensory information and coordinating movement and vital functions, is the:

• A. Lungs
• B. Brain
• C. Kidneys
• D. Stomach

Correct answer: B

Rationale: The correct answer is B: Brain. The brain serves as the command center of the human body, receiving sensory information from various parts of the body and coordinating responses. It is responsible for controlling movement, regulating vital functions such as breathing and heart rate, and processing thoughts and emotions. The lungs (A), kidneys (C), and stomach (D) each have specific functions within the body, but they do not serve as the central command center like the brain does. Therefore, the brain is the correct answer to this question.

5. What is the recommended daily intake of protein for adults to maintain healthy muscle mass?

• A. 0.5 grams per kilogram of body weight
• B. 1 gram per kilogram of body weight
• C. 1.5 grams per kilogram of body weight
• D. 2 grams per kilogram of body weight

Correct answer: C

Rationale: The recommended daily intake of protein for adults to maintain healthy muscle mass is 1.5 grams per kilogram of body weight. Protein is essential for muscle repair and growth, and consuming an adequate amount helps support overall muscle health. 1 gram per kilogram of body weight is generally recommended for sedentary individuals, but for those looking to maintain or build muscle mass, a higher intake of 1.5 grams per kilogram of body weight is advised. Consuming too little protein can lead to muscle loss, while consuming too much may strain the kidneys. Therefore, 1.5 grams per kilogram of body weight strikes a balance for most adults looking to support their muscle health.

6. A symbiotic relationship where one organism benefits and the other is not harmed is called:

• A. Mutualism
• B. Commensalism
• C. Parasitism
• D. Predation

Correct answer: B

Rationale: Rationale: A) Mutualism: In mutualism, both organisms involved benefit from the relationship. B) Commensalism: In commensalism, one organism benefits while the other is neither helped nor harmed. This is the relationship described in the question. C) Parasitism: In parasitism, one organism benefits at the expense of the other organism, which is harmed. D) Predation: In predation, one organism (predator) kills and consumes another organism (prey) for food.
