I think the answer is D because of natural selection.  The insects that survived had specific genes that made them resistant.  They then passed those genes to their offspring and eventually the entire population was resistant.  Hope this helps.

How does afforest station help to balance environment​
Pani-rosa [81]

Explanation:

The ever and ever increasing demand for wood fuel, gas, timber, building materials, and many other consumer products are exerting more and more pressure on the earth’s natural resources, living organisms, and natural cycles responsible for maintaining a balance on earth.

Natural resources such as the water systems, fertile soil, clean air, vegetation cover, wildlife, indigenous plant species, and natural cycles such as the oxygen and nitrogen cycles, and food chains need trees for their continuity and balance.

Define and describe osmosis​
ankoles [38]

Answer:

Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.

Explanation:

Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.

Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.
