Using the carbohydrate glucose and this chart above with average bond energies, add up the potential energy available in that molecule in all bonds. Now using the fatty acid and this chart, add up the potential energy available in that molecule if all bonds.

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

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).
