compare and contrast the functions of carbohydrates and lipids. explain the function that carbohydrates and lipids have in common. next, describe other functions each of these biomolecules have that are unique to their category.

c. would be the answer : )

explanation:

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).

the answer u all are looking for is 4000000000000000000000 million years.
