Which of the following statements about prokaryotic reproduction and genetic recombination is true?

Prokaryotes reproduced fission, a form of sexual reproduction and genetic recombination

Genetic recombination in prokaryotes can take place by taking up DNA from the environment. This is called transfection

During conjugation, a donor cell shares a DNA with a receptor cell

Phages are not considered to be a source of genetic recombination in prokaryotes

CRSPR-Cas is the asexual reproduction system in prokaryotes

the answer is C; During conjugation, a donor cell shares a DNA with the recipient cell.

Explanation:

Bacterial conjugation involves the transfer of genetic matter between cells either via direct cell to cell contact or by the means of a pilus.

The donor cell produces pilus which attaches to the recipient cell and brings the cells together, and then a single strand of DNA is then transferred to the recipient cell.

answer: 21

step-by-step explanation:

divide 630 by 30. 30 goes into 630 21 times

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.
