The primary function of polysaccharides attached to the glycoproteins and glycolipids of animal cell membranes is a) to facilitate diffusion of molecules down their concentration gradients b) to actively transport molecules against their concentration gradients c) to maintain the integrity of a fluid mosaic membrane d) to maintain membrane fluidity at low temperatures e)

d. groundwater flows through the subsoil and deposits minerals.

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).
