While performing an experiment on the enzyme amylase, macy uses three different ph solutions: ph 3.0, ph 4.0, and ph 6.7. she finds that all the starch is broken down fastest at ph 6.7. how would you justify these findings? the optimum ph for amylase is ph 6.7, at which the rate of reaction is the highest. the minimum ph for amylase is ph 6.7, after which the reaction takes minimum time for completion. the optimum ph of amylase is between ph 3.0 and ph 4.0, at which the enzyme takes maximum time for completion. nextreset

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.

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).
