What extreme conditions do microbes exist under at bleeding glacier sites? Select the TWO answers that are correct. high pressure low carbon high salt and iron low oxygen high temperature

the cell cycle is the final answer! : )

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).
