Reading

1. The final sentence highlights the need for

Correct answer: C

Rationale: The emphasis on "international cooperation," "robust scientific research," and "adapting" suggests a focus on collaborative and multi-faceted solutions, aligning with C.

2. In meiosis, how many divisions occur, and how many daughter cells are produced?

Correct answer: B

Rationale: Rationale: In meiosis, there are two divisions: meiosis I and meiosis II. During meiosis I, homologous chromosomes separate, resulting in two daughter cells with half the number of chromosomes as the parent cell. In meiosis II, sister chromatids separate, resulting in a total of four daughter cells, each with a haploid set of chromosomes. Therefore, meiosis involves two divisions and produces four daughter cells.

3. The ability of a substance to dissolve in another is called:

Correct answer: A

Rationale: Solubility refers to the extent to which one substance can dissolve in another to form a homogeneous solution.

4. Which of the following questions is NOT appropriate for scientific investigation?

Correct answer: C

Rationale: Science deals with observable, measurable phenomena using evidence-based methods. Questions about subjective experiences and abstract concepts like meaning fall outside the realm of scientific inquiry.

5. Which hormone is crucial for stimulating sperm production in males?

Correct answer: C

Rationale: The correct answer is C: Testosterone. Testosterone is the primary male sex hormone and is crucial for stimulating sperm production in males through the process of spermatogenesis. It is produced in the testes and plays a key role in the development and maintenance of male reproductive tissues, including the testes and prostate. Estrogen and progesterone are primarily female sex hormones, while insulin regulates blood sugar levels and metabolism. Therefore, testosterone is the hormone specifically responsible for stimulating sperm production in males.

6. What is the process of cells responding to external stimuli, such as chemicals, temperature, or touch, called?

Correct answer: A

Rationale: Rationale: A) Signal transduction is the process by which cells respond to external stimuli, such as chemicals, temperature, or touch. When a cell receives a signal from its environment, it initiates a series of molecular events that ultimately lead to a specific cellular response. This process involves the transmission of signals from the cell surface to the interior of the cell, where they can trigger various cellular activities. B) Homeostasis refers to the ability of an organism to maintain internal stability and balance in response to external changes. While signal transduction plays a role in maintaining homeostasis by allowing cells to respond to external stimuli, it is not the specific process of cells responding to external stimuli. C) Adaptation is the process by which an organism adjusts to its environment over time through genetic changes or behavioral modifications. While cells can adapt to changes in their environment, the process of cells responding to external stimuli
