Marina CMI [18]

Answer:

Dehydration

Explanation:

What causes bacteria to die in an extremely salty environment is dehydration due to the loss of osmotic balance in their cells.

Water molecules would normally move from the region of high water potential or low solute concentration to the region of low water potential or high solute concentration through a biologically permeable membrane.

<em>An extremely salty environment would be hypertonic to the cells of bacteria and the cell walls of bacteria act as biologically permeable membranes. Hence, the bacteria cells lose water due to the osmotic movement of water from their cells to the surrounding salty environment. </em>

Carbohydrate layer on the plasma membrane includes all of the following except:
irinina [24]

Answer:

c) Gives a cell its distinctive characteristics

Explanation:

Carbohydrates perform two main functions in the cell's membrane: <em>they participate in cell recognition and adhesion</em> (cell-cell signaling or cell-pathogen interactions), they also have a structural role as a physical barrier.

Most of the carbohydrates linked to the membrane are in the form of <em>glycoproteins oy glycolipids</em>, these are the molecules that share information and recognize host cells. <em>Glycocalyx </em>is another way we find carbohydrates in the cell membrane, this layer has cell-adhesion molecules that enable cells to adhere to each other.

I hope you find this information useful! Good luck!
