1. What is the process of cells becoming specialized to perform specific functions called?

Correct answer: B

Rationale: Cell differentiation is the process by which cells become specialized to perform specific functions. During differentiation, cells acquire specific structures and functions that allow them to carry out particular roles in the body. Cell division refers to the process by which a parent cell divides into two or more daughter cells. Cell growth is the process by which cells increase in size and number. Cell regeneration is the process by which new cells are produced to replace damaged or lost cells in an organism. Therefore, in this context, the process of cells becoming specialized to perform specific functions is best described as cell differentiation.

2. What is a characteristic feature of a convex lens?

Correct answer: A

Rationale: A convex lens is characterized by its ability to converge light rays. The convex lens is thicker in the middle and thinner at the edges, causing light rays passing through it to converge or come together at a focal point on the opposite side of the lens. This convergence of light rays is what distinguishes convex lenses. Choice B is incorrect as convex lenses do not diverge light rays. Choice C is incorrect as convex lenses do not focus sound waves but rather light waves. Choice D is incorrect as convex lenses can create both real and virtual images, not just virtual images.

3. Which of Mendel's Laws states that alleles for a gene segregate during gamete formation?

Correct answer: B

Rationale: The Law of Segregation, proposed by Gregor Mendel, states that alleles for a gene segregate during gamete formation. This means that each parent passes on only one allele for each gene to their offspring. This law explains how genetic diversity is maintained and how different combinations of alleles are generated in offspring. The Law of Independent Assortment (option A) is not the correct answer as it states that alleles of different genes assort independently of each other during gamete formation, not specifically alleles of a single gene. The Law of Dominance (option C) is incorrect as it pertains to the expression of alleles rather than their segregation during gamete formation. The Law of Probability (option D) is also incorrect as it is a general concept describing the likelihood of events, not specifically related to alleles segregating during gamete formation.

4. What is the term for the maximum amount of solute that can dissolve in a solvent at a specific temperature and pressure?

Correct answer: B

Rationale: Solubility is the correct term for the maximum amount of solute that can dissolve in a solvent at a specific temperature and pressure. Molarity is a measure of concentration, not the maximum amount that can dissolve. Concentration is a general term for the amount of solute present in a given amount of solvent. Saturation is related to solubility but specifically refers to a state where no more solute can be dissolved in the solvent.

5. What are the components of the male internal genitalia and their functions?

Correct answer: B

Rationale: The testes play a crucial role in male reproduction by producing sperm and testosterone. Sperm production is essential for fertility, while testosterone is responsible for the development of secondary sexual characteristics. The epididymis functions to store and mature sperm, allowing them to become motile. The prostate gland, not listed among the choices, secretes fluid that nourishes and protects sperm. The urethra serves the purpose of conducting both urine and semen out of the body, enabling the excretion of waste and reproductive fluids.
