1. Which of the following areas has the least amount of sweat glands?

Correct answer: B

Rationale: The correct answer is B - Palms. The palms have the least amount of sweat glands compared to the other options listed. The back, axilla (armpits), and forehead are all areas with a higher concentration of sweat glands in the body. The palms have fewer sweat glands to minimize water loss and maintain a better grip for activities requiring precise and controlled movement. The back, axilla, and forehead have more sweat glands to assist in thermoregulation and cooling of the body, while the palms have fewer sweat glands for functional reasons related to grip and dexterity.

2. What is the unit of measurement for force in the International System of Units (SI)?

Correct answer: A

Rationale: The unit of measurement for force in the International System of Units (SI) is the Newton (N). One Newton is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared. Therefore, the correct answer is Newton (N). The other choices are incorrect because: B) Kilogram (kg) is a unit of mass, not force; C) Joule (J) is a unit of energy; D) Meter per second squared (m/s²) is a unit of acceleration, not force.

3. What is the main function of vacuoles in plant cells?

Correct answer: D

Rationale: Vacuoles in plant cells primarily function as storage organelles. They store water, enzymes, pigments, and waste products, helping to maintain turgor pressure within the cell. This turgor pressure provides structural support for the plant cell. While vacuoles can also participate in transporting substances within the cell, their main role is storage. The synthesis of proteins and lipids is mainly handled by other organelles such as the endoplasmic reticulum and Golgi apparatus. Choice A is incorrect because while vacuoles indirectly contribute to structural support by maintaining turgor pressure, their primary function is storage. Choice B is incorrect as vacuoles are not primarily responsible for transporting substances in and out of the cell. Choice C is incorrect as vacuoles do not synthesize proteins and lipids; this function is carried out by other organelles.

4. Which vitamin plays a vital role in muscle function and helps prevent muscle weakness and fatigue?

Correct answer: C

Rationale: Vitamin D is the correct answer as it plays a crucial role in muscle function by helping prevent muscle weakness and fatigue. It is essential for maintaining muscle strength and function, as well as supporting overall bone health. Vitamin D deficiency can lead to muscle weakness and fatigue, emphasizing its significance for muscle health. Vitamin A does not directly impact muscle function in the same way as Vitamin D. Although Vitamin B12 is important for neurological function and red blood cell production, it is not primarily known for its role in muscle function. Vitamin E is more commonly associated with its antioxidant properties and its role in protecting cells from damage, but it is not specifically linked to muscle function and preventing muscle weakness and fatigue.

5. Two nursing students will be completing a scientific experiment measuring the mass of chewed gum after one-minute chewing increments. Which lab equipment will the students most likely use?

Correct answer: A

Rationale: The correct answer is A: Triple beam balance. A triple beam balance is the most suitable lab equipment for measuring mass accurately, which is necessary for this experiment. An anemometer measures wind speed, a hot plate is used for heating substances, and a microscope is used for magnifying objects, none of which are relevant to measuring the mass of chewed gum.
