Anatomy

1. Which of the following terms refers to a muscle twitch, a single forceful contraction of a muscle fiber?

Correct answer: C

Rationale: The correct answer is C: "Fasciculation." A muscle twitch refers to the involuntary contraction of a small group of muscle fibers. Tetanus (choice A) is a sustained contraction of a muscle caused by rapid stimulation. Trembling (choice B) is the shaking or quivering of muscles. Rigidity (choice D) refers to stiffness or inflexibility in muscles. Fasciculation is the term that specifically describes a muscle twitch, which is a single forceful contraction of a muscle fiber. Therefore, choice C is the most appropriate term for this scenario.

2. A stop sign has five equal sides, each measuring 25cm. What is its perimeter?

Correct answer: B

Rationale: Multiply the side length by the number of sides: perimeter = number of sides * side length = 5 * 25cm = 125cm.

3. What is the molar mass of Ca(NO3)2?

Correct answer: b

Rationale: Calculate the molar mass: Ca(40.08) + 2N(14.01) + 6O(16.00) = 132.1 g/mol.

4. What is the main difference between white and brown adipose tissue?

Correct answer: B

Rationale: The main difference between white and brown adipose tissue lies in their function and energy metabolism. White adipose tissue is primarily involved in energy storage, while brown adipose tissue is responsible for energy expenditure through thermogenesis. Brown adipose tissue contains a higher density of mitochondria and a unique protein called uncoupling protein 1 (UCP1) that allows for the generation of heat. This key distinction in function and energy metabolism sets white and brown adipose tissue apart, making option B the correct answer.

5. A water fountain has a spherical base (diameter 50cm) and a cylindrical body (diameter 30cm, height 80cm) on top. What is the total surface area of the fountain (excluding the water surface)?

Correct answer: C

Rationale: Calculate the surface area of the sphere and the cylinder separately, then add them up.

6. Square: A garden bed has a side length of 8 meters. What is its perimeter?

Correct answer: D

Rationale: Since all sides are equal, multiply the side length by 4: perimeter = 4 * side length = 4 * 8m = 32m.
