Which cellular process would be affected first if the structure labeled 3 were destroyed? A. transport
B. photosynthesis
C. respiration
D. reproduction

a bird that nests only in a particular tree species.

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).
