The correct option is B) Meiosis provides for chromosomal variation in the gametes produced by an organism.

Explanation:

Meiosis can be described as a cell division process by which the chromosome number gets reduced to half. This is because half of the chromosomes will come from the female parent and half of the chromosomes will come from the male parent in the offsprings that will be produced when they interbreed.

During the process of meiosis, crossing over and homologous recombination of chromosomes occurs which allows genetic variations among species.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
