The population of peppered moths have changed over time. The population has changed from primarily light colored to dark colored moths. This is an example of... a
Mimicry
b
Natural Selection
c
Selective Breeding
d
Camouflage

the answer is c) an oak tree

the answer is c.) there is a warm front in region a and a stationary front in region b.

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).
