Homogenization refers to the addition of and to separate dna from the cell membranes and proteins.

Homogenization refers to the addition of detergents and salt (protease) to separate DNA from the cell membranes and proteins.

Explanation:

DNA or the deoxyribonucleic acid is said to be the nucleic martial that is present inside the nucleus of a cell, in order to extract the DNA from the cell, the external  membranes have to be broken and the cell contaminants such as the proteins should be denatured and separated out, the detergent breaks the cell membranes whereas the salt precipitates the DNA out.

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.
