During photosynthesis, the following reaction takes place: carbon dioxide + water + light energy sugar + oxygen During cellular respiration, the following reaction takes place: sugar + oxygen carbon dioxide + water + chemical energy

it would be c. xylem.

straight or amphibians are homeothermic to thermal

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).
