What human acting promotes the ability to find this species of plant and discover its potential use for medicines?

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse

answer; both surfaces of the membrane are nonpermeable

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).
