Answer:

the process whereby nonsister chromatids exchange genetic material

Explanation:

Crossing-over is a unique phenomenon which occurs only in the prophase I stage of meiotic division i.e. meiosis I. It is the process whereby nonsister chromatids of homologous chromosomes (similar but non-identical chromosomes from male and female parents) exchange their genetic material.

This exchange between nonsister chromatids aids in genetic variation among species that reproduce sexually via meiosis. Hence, meiosis, which is peculiar to sexually-reproducing organisms is the only way that promotes genetic variation in species.

Vsevolod [243]

To evaporate only 1 ml of water, 540 calories per ml or g of water is required.

About 540 calories per ml or g of water are needed to convert one gram of water that is present in liquid state into vapor form under normal pressure. The evaporation of  water at removing excess heat from our body is very effective in lowering the temperature of our body and in maintaining homeostasis.

Our body removes heat with the help of water that is move from the small openings present on our skin in the form of sweats so we can say that evaporation of  water at removing excess heat from our body is very effective.
