physics

1. What phenomenon occurs when a wave encounters a change in medium causing a change in its speed and direction?

Correct answer: a

Rationale: Refraction happens when a wave changes its speed and direction due to encountering a change in medium.

2. What is the SI unit of measurement for acceleration?

Correct answer: d

Rationale: Acceleration is measured in meters per second squared (m/s²) in the SI unit system.

3. 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.

4. Which of the following describes the difference between prokaryotic and eukaryotic cells?

Correct answer: A

Rationale: The correct answer is A: 'Prokaryotic cells have a nucleus, while eukaryotic cells don't.' Prokaryotic cells lack a membrane-bound nucleus and other membrane-bound organelles, while eukaryotic cells have a true nucleus enclosed within a nuclear membrane. This distinction is a fundamental difference between the two cell types. Choice B is incorrect because eukaryotic cells are actually more complex than prokaryotic cells due to their membrane-bound organelles. Choice C is incorrect because prokaryotic cells lack membrane-bound organelles. Choice D is incorrect because eukaryotic cells have both a true nucleus and membrane-bound organelles, unlike prokaryotic cells. Understanding this key difference is crucial in understanding the diversity of cell types in living organisms.

5. What is the milky-white fluid transported by the lymphatic vessels called?

Correct answer: C

Rationale: The milky-white fluid transported by the lymphatic vessels is called 'Chyle.' Chyle is formed in the small intestine during the absorption of fats. It primarily consists of lymph and emulsified fats. Plasma refers to the liquid component of blood, while blood carries red blood cells, white blood cells, platelets, and plasma. Mucus is a slimy substance produced by mucous membranes. Therefore, option C, 'Chyle,' is the correct answer in this context.

6. In a horizontal chart, the lowest level worker is located at the

Correct answer: B

Rationale: In a horizontal chart, the lowest level worker is typically positioned at the leftmost side, with higher-level workers placed to the right. This arrangement signifies hierarchy, with the top level usually being on the rightmost side. Therefore, the correct answer is B: 'Middle,' as the lowest level worker is situated towards the left of the chart, not the extreme left or right. This positioning helps visually represent the organization's structure and indicates the progression from lower to higher levels as one moves from left to right on the chart.
