Acompetent bacterial strain with genes a, b, and c is transformed by a donor bacterial fragment. cotransformation frequencies for each gene pair are as follows: a and b 0.04% a and c 0.02% b and c 0.0064% which conclusion can be definitively made from this data?
a) genes b and c are farthest apart.
b) gene order is a, b, then c.
c) gene a is closer to c than to b.
d) gene b is closer to c than to a.
e) cotransformation of b and c is so frequent, they must be one gene

a) Genes b and c are farthest apart.

Explanation:

Transformation occurs when a competent bacteria cell takes up genetic material from the environment. Usually a donor cell donates its gene fragment  which is then incorporated into the chromosome or plasmid of recipient bacterial cell.

Cotransformation occurs when two genes are taken up together by the recipient. The closer the genes lie to each other, more are the chances of them being taken up together. Contransformation frequency will be higher if two genes are close to each other. Here, cotransformation frequencies between three genes are given. Amongst them, the lowest frequency is 0.0064% which is present between gene b and c. Hence, gene b and c are the farthest apart.

the answer is cell division : )

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.
