The following events are part of a negative feedback mechanism. In which order do they occur? 1. Body temperature falls,
2. Blood flow to the skin and sweating are decreased
3. Sensors detect a temperature change.
4. Blood vessels in the skin contract and sweat gland activity decreases.

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).
