Help me on this question and NO LINKSS

the first one

Explanation:

parasites are usually much more numerous than their hosts, but predators are usually less numerous than their prey.

Im not 100% sure its just what i think it is

I mostly think it's B, because parasites give effects on their host but not at the same time.

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
