How doResponse area are proteins that Response area up the rate of a reaction. Enzymes are a type of Response area. The difference between a catalyst and an enzyme is that the enzyme is a Response area and is organic; catalysts do not have to be organic nor do they have to be proteins. An enzyme works by Response area the activation energy of a reaction. Once the reaction occurs, the enzyme is Response area so that it can be used again in other reactions. enzymes make chemical reactions more efficient?

C. gemstones they are the only non metallic mineral from the list.

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
