1. How is power related to time?

• A. Power is inversely proportional to time
• B. Power is directly proportional to time
• C. Power is unrelated to time
• D. Power is the product of time and work

Correct answer: c

Rationale: Power is the rate at which work is done or energy is transferred, and it is not directly linked to time.

2. What is the scientific name for the common housefly?

• A. Musca domestica
• B. Drosophila melanogaster
• C. Apis mellifera
• D. Anopheles gambiae

Correct answer: A

Rationale: Rationale: - Musca domestica is the scientific name for the common housefly. This species is known for being a common pest found in and around human habitations. - Drosophila melanogaster (option B) is a species of fruit fly commonly used in genetic research. - Apis mellifera (option C) is the scientific name for the western honeybee. - Anopheles gambiae (option D) is a species of mosquito known for being a vector of malaria.

3. Which of the following nutrients is essential for muscle growth and repair?

• A. Vitamin C
• B. Protein
• C. Carbohydrates
• D. Fat

Correct answer: B

Rationale: The correct answer is B: Protein. Protein is essential for muscle growth and repair because it provides the necessary building blocks called amino acids. These amino acids are crucial for repairing and building muscle tissue, which is essential for overall muscle growth and recovery. While vitamins like Vitamin C play a role in overall health and immune function, they are not directly involved in muscle growth and repair. Carbohydrates provide energy for workouts, but they are not the primary nutrient needed for muscle repair. Fat is important for overall health but is not as directly involved in muscle growth and repair as protein is.

4. Which blood vessels are responsible for carrying oxygenated blood away from the heart to the rest of the body?

• A. Veins
• B. Arteries
• C. Capillaries
• D. Venules

Correct answer: B

Rationale: The correct answer is B: Arteries. Arteries are blood vessels that carry oxygenated blood away from the heart to the rest of the body. They have thick and elastic walls to withstand the high pressure generated by the pumping action of the heart. Veins, on the other hand, carry deoxygenated blood back to the heart, while capillaries are tiny blood vessels where the exchange of oxygen and nutrients occurs. Venules are small veins that collect blood from capillaries and transport it to larger veins. Therefore, arteries are specifically designed to transport oxygenated blood away from the heart, making them the correct choice in this question.

5. Which sentence uses the modal verb "should" correctly?

• A. You should have studied harder for the exam.
• B. I should be going now.
• C. She said she should have taken a different route.
• D. They should be arriving any minute now.

Correct answer: B

Rationale: Option B conveys an intention or expectation regarding the present or near future.

6. Which of the following is NOT a characteristic of mitosis?

• A. The replication of DNA
• B. The condensation of chromosomes
• C. The separation of sister chromatids
• D. The formation of haploid cells

Correct answer: D

Rationale: Rationale: A) The replication of DNA is a characteristic of mitosis. Before cell division occurs, the DNA is replicated to ensure that each daughter cell receives a complete set of genetic information. B) The condensation of chromosomes is a characteristic of mitosis. During mitosis, the chromosomes condense and become visible under a microscope as distinct structures. C) The separation of sister chromatids is a crucial step in mitosis. During anaphase, the sister chromatids are pulled apart and move to opposite poles of the cell to ensure that each daughter cell receives a complete set of chromosomes. D) The formation of haploid cells is NOT a characteristic of mitosis. Mitosis results in the formation of two identical diploid daughter cells, each containing the same number of chromosomes as the parent cell. Haploid cells are typically formed through the process of meiosis, not mitosis.
