Physics

1. A car skids on a wet road. What is the main force preventing the car from stopping?

Correct answer: A

Rationale: Friction opposes the motion of the car, trying to bring it to a stop. However, due to the wet surface, the friction force is not enough to overcome the car's inertia.

2. During exercise, oxygen is used to convert glucose into energy for muscles. This process is called:

Correct answer: A

Rationale: The correct answer is 'A: Aerobic respiration.' During exercise, muscles require energy to function, and oxygen plays a crucial role in converting glucose into energy through aerobic respiration. This process occurs in the mitochondria of cells and involves the breakdown of glucose to produce ATP, the cell's energy currency. Aerobic respiration is efficient and produces a higher yield of ATP compared to anaerobic respiration or glycolysis alone. Anaerobic respiration (option B) and glycolysis (option C) are also involved in energy production but do not rely on oxygen. Lactic acid fermentation (option D) occurs when there is not enough oxygen available, leading to the accumulation of lactic acid. Therefore, the most appropriate answer is 'A: Aerobic respiration.'

3. Which phrase best describes the tone of the passage?

Correct answer: C

Rationale: The passage presents factual information without injecting personal opinions or emotions. A, B, and D suggest tones not present in the passage's neutral delivery.

4. What is the scientific study of the relationships between organisms and their environment?

Correct answer: C

Rationale: Rationale: A) Zoology is the scientific study of animals. B) Botany is the scientific study of plants. C) Ecology is the scientific study of the relationships between organisms and their environment, including the interactions between living organisms and their physical surroundings. D) Genetics is the scientific study of genes, heredity, and variation in living organisms, which is not directly related to the relationships between organisms and their environment.

5. The sentence "The audience was captivated by the speaker's compelling story" implies that the audience:

Correct answer: C

Rationale: "Captivated" suggests the audience was completely held by the speaker's story.

6. What is the primary hormone released by the parathyroid glands?

Correct answer: C

Rationale: The primary hormone released by the parathyroid glands is Parathyroid hormone (PTH), which plays a crucial role in regulating calcium levels in the body. Insulin is produced by the pancreas to regulate blood sugar levels and is unrelated to the parathyroid glands. Calcitonin is produced by the thyroid gland and helps regulate calcium levels but is not the primary hormone released by the parathyroid glands. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism and is also not released by the parathyroid glands. Therefore, the correct answer is C: Parathyroid hormone (PTH).
