Agroup of students has performed an experiment to study the ideal temperature for the maximum activity of biological enzymes. enzymes are specific to their environment; in other words, they work best at a specific ph and specific temperature. which graph represents optimum enzyme activity at approximately 37 degrees celsius?
refer to figures below.

The first graph represents such an enzyme.
This is because the enzyme demonstrates greatest activity at approximately 37 °C but then the activity starts to decrease due to the denaturing of the enzyme.

The correct answer is  b) 

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.
