The cell wall of a bacterial cell Multiple Choice prevents collapse of the cell membrane in hypertonic conditions. allows for the escape of water in hypotonic conditions. prevents lysis of the cell in hypotonic conditions. prevents lysis of the cell in hypertonic conditions.

The correct answer is option c. prevents lysis of the cell in hypotonic conditions.

Explanation:

If a bacterial cell is placed in a hypertonic solution, then the water from the bacteria will move into the solution as the water moves from a higher concentration to a lower concentration. This leads to shrinkage of the bacterial cell but not lysis of the cell. Therefore in the hypertonic solution, the cell does not lyse.

On other hand, if the bacterial cell is placed in a hypotonic solution, the water from the solution will enter into the bacteria due to a higher concentration of water is present in the solution than the cell and this will cause swelling of the cell. The cell wall is a rigid cell structure that prevents the lysis of the cell in the hypotonic solution.

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.

layer 3 is younger than layer 6.
