Decide whether each statement describes the life cycle of a low-mass star or a high-mass star.
when a
-mass star leaves the main sequence, it becomes a red giant before creating a planetary nebula and becoming a white dwarf.
when a
-mass star leaves the main sequence, it becomes a red supergiant before creating a supernova and becoming either a neutron star or black hole.

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).
