Which statement most directly demonstrates a way that the geosphere is involved in the nitrogen cycle?

"a.) well–developed vascular system."

. ph changes the ability of them he enzyme to dissolve in water.

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).
