You are buying an air conditioner. The Energy Star brand is $300 and the standard is $200. They have the same cooling capacity, but the Energy Star costs 5 cents/hour less to run. If you run the air conditioner 12 hours a day, how long does it take to recover the cost?

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).

then go eat. lol.brainliest
