Someone plz help

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

it's c. (to reduce the greenhouse effect/carbon gasses)

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
