An example of von baer's principles is the pharyngeal pouches of mammals that are indistinguishable from aquatic gill pouches in early development. in mammals the pouches do not develop in to gills, but form the: (list three of the five structures)

i believe it would be c: tons.

it's d - life cycles - apex

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).
