Select all of the food items where microbial growth is controlled by means of osmotic pressure.
olga nikolaevna [1]
<span>The answer would be:
Jellies
Salt cured meats
Honey

High osmotic pressure can be used as a natural preservative. In high osmotic pressure, the microbes will hardly survive as their surrounding concentration is too high and induce severe osmosis. The osmosis will take the microbes water, makes it shrink continually lead to the microbes death. 
In those 3 foods, there is a high concentration of sugar or salt that increase the osmotic pressure.</span>

The processes of diffusion and active transport are both used to * break down molecules to release energy move molecules into or
luda_lava [24]

Answer:

move molecules into or out of cells of the body

Explanation:

Majorly, there are two types of transport used by living cells. These are; passive and active transport. Passive transport involves the movement of molecules down a concentration gradient without the need for energy (ATP) input. Example is DIFFUSION AND OSMOSIS.

On the other hand, active transport is a type of transport that moves molecules against a concentration gradient (low to high) with the aid of energy input (ATP). Example is sodium-pottasium proton pump.

Although there are obvious differences between these two processes (diffusion and active transport), but they both MOVE MOLECULES INTO OR OUT OF CELLS OF THE BODY.
