Why are cells relatively small?

1 answer:

8 0

Cells are so small so the surface area and volume of them can be proportional to each other. This helps with the efficiency of the cell's absorption and waste expulsion processes. Also by the cell's smallness, communication from the nucleus to other organelles is fast and the cell can be regulated while the conditions for diffusion are still ideal.Its because they need to be able to diffuse through materials easily. Also, materials inside and outside of the cell need to easily pass through the cell membrane, which makes it harder and slower for the materials to pass through the cell membrane.

A geologist is studying a sand dune. The sand dune was formed as wind deposited sand against an obstruction. What process create

EastWind [94]

<h2>The correct answer is: Deflation.</h2>

Explanation:

In geology, Deflation can be defined as the process by which loose, light weight and small particles formed by the weathering of rocks, erosion of top-soil of the earth crust or the dust and sand particles are carried from one place to another by the action of wind.
When these particles hit or strike an obstruction like a mountain or hill they fall down on the ground.
Gradually with time, numerous such particles fall down and accumulate on the ground after striking an obstruction and eventually result in the formation of a sand dune.
