Henrietta lacks had a tumor whose cells changed medical research. this cell line is called what?

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.

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).
