Can someone help me? The question is State two scenarios that demonstrate the process diffusion​
gtnhenbr [62]

Answer:

One could be in the cell. The cell respires, thus producing carbon dioxide in it. So the concentration builds up in the cell. Diffusion is the net movement of particles from a region of high concentration to a region of low concentration, and the carbon dioxide concentration outside the cell is less, therefore the carbon dioxide molecules moves outs of the cell.

Another scenario is when perfume is sprayed into the air. The perfume particles collides with the air particles (lower or no concentration of perfume). This process goes on and on. This is diffusion since the concentration perfume particles collides with the less concentrated particles of perfume.

Lake Mojave is an ancient lake that has dried up and no longer exists in the Mojave desert in California. Which environmental co
Goshia [24]

The correct answers are:

- Decrease in rainfall in the Mojave desert;

The decrease in rainfall can be devastating to a lake's waters and biodiversity. The decrease in rain usually causes bigger loss of water through evaporation than water coming in the lake, so over time it will dry out, or just small pieces of it will remain.

- Decrease in runoff that flows into Mojave Lake;

If the amount of water that comes into the lake decreases, it can be fatal to it, and in a very short period of time, since the lake will be losing more water than it gets in.

- Increase in blocked streams that flow into Mojave Lake;

Naturally, streams can be blocked and redirected, so if this happens, we have the same situation from before, where the water income is smaller than the water loss of the lake.
