The answer is A. deforestation

Trees and another various type of vegetations played really important roles in absorbing water (through their pores/roots)
So, when deforestation happens, we cut down many of these trees and vegetation, which heavily reduced the absorption capability in that area,  which eventually cause desertification in the long run.

A gardener is concerned that her greenhouse is getting too hot from too much light, and seeks to shade her plants with colored t
valkas [14]
<span>In getting her plants to grow, the gardener should use the color blue for her colored translucent sheets. The reason for this is because it will be absorbed by the plants, causing them to get the light absorption that they so desperately need. Other colors, such as green, are absorbed into plants (as can be observed by their green colors), and thus they do not absorb the light through this color.</span>

The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid
Leona [35]

Answer:

the concentration of the solute is lower inside the cell than outside it

Explanation:

This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.

This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.
