This simple bacteria cell has the same structure as more complex cells. it controls what comes in to and leaves the cell and also maintains homeostasis. it is the

well the answer is 2!

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).

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"
