The process of movement of water from a hypotonic solution to a hypertonic solution across a semipermeable membrane is:
A. Diffusion
B. Active transport
C. Osmosis
D. Facilitated diffusion

Correct Answer: Option C


Explanation:
Osmosis is the net diffusion of water through a selectively permeable membrane from a region of low solute (high water potential) to high solute (low water potential).

Question #2
Crossing over occurs between:
A. Two different cells
B. Sister chromatids of the same chromosome
C. Non-sister chromatids of homologous chromosomes
D. Non-homologous chromosomes

Correct Answer: Option C


Explanation:
Crossing over is the exchange of genetic material between non-sister chromatids of homologous chromosomes during prophase I of meiosis. This leads to genetic recombination. Sister chromatid exchange does occur but crossing over specifically refers to the exchange between homologues.

Question #3
The process by which traits are transferred from parents to offspring is:
A. Heredity
B. Variation
C. Mutation
D. Evolution

Correct Answer: Option A


Explanation:
Heredity (inheritance) is the transmission of genetic information and traits from parents to offspring through genes. Variation refers to differences among individuals, evolution is the change in heritable traits over generations, and mutation is a change in DNA sequence. Mendel's laws describe the patterns of heredity. Genes are the units of heredity.
