The major function of the cell wall is to Choose one: A. serve as a rigid barrier to prevent cell lysis. B. serve as a barrier to prevent entry of molecules into the cytoplasm. C. allow for bacterial motility. D. constrain bacterial cell growth.

A. serve as a rigid barrier to prevent cell lysis

Explanation:

The presence of a cell wall is a characteristic feature of the bacteria. The cell wall surrounds the bacterial cell membrane and is composed of the peptidoglycan molecule or murein (unique molecule present in only bacteria).

The cell wall performs many functions in the bacteria like in the transport of molecules, protects the cell and the most important feature is that it prevents the rupture of the bacterial cell from the osmotic lysis. As the bacteria moves from one environment to another, the water move into the cell will cause the cell to lysis but the presence of the cell wall prevents the cell from the lysis.

Thus, Option-A is the correct answer.

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.
