The answer is natural selection.

In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. Red and green colors of butterflies increased the chance of their <span>survival and reproduction, so these traits will pass to the next generation.</span>

Explain the water problems encountered by cells in a
vovikov84 [41]

Answer:

The plant cell becomes turgid

Explanation; freshwater contains a low amount of salt concentration .when cells are placed in it,it creates an osmotic difference, as the cytoplasm of the cell would be of higher concentration than the surrounding water .as a result,water moves into the cell by osmosis.

Most Unicellular organisms has organelles such as contractile vacuole to expel excess water out of it's cell.if the animal cell is unable to expel water,it bursts.

In plants cells,the cell swells and the swelling is checked by the inflexible and rigid cell wall.

The cell wall of plants are made of cellulose, lignin and pectin.

An experiment was done by Gierer and Schramm where they exposed plant tissue to purified RNA from tobacco mosaic virus, and the
cestrela7 [59]

Answer:

See the answer below

Explanation:

A DNase is also known as deoxyribonuclease and it is an enzyme that catalyzes the degradation of deoxyribonucleic acid by cleaving the phosphodiester linkage in their structures. Thus,<em> if the RNA is treated with a DNase before the plants are exposed to it, it will not make any difference. The plants will develop the same types of lesions as if they have been exposed to the mosaic virus.</em>

Unlike DNase, RNase is a ribonuclease, an enzyme that is capable of carrying out catalytic degradation of ribonucleic acids. <em>This means that if the RNA is treated with RNase before the plants are made to be exposed to it, they will not develop the lesions because the RNA would have been degraded by the enzyme.</em>

A protease is an enzyme that degrades the structure of proteins. <em>Treating a RNA with protease will thus have no effect on the structure of the RNA. Exposing the plants to the protease-treated RNA will make no difference. The plants will still come down with the lesions as if they have been exposed to the virus. </em>
