Which statement is true regarding speed, velocity, and acceleration?
A. Velocity is speed in a certain direction; acceleration is a change in velocity.
B. Acceleration is speed in a certain direction; velocity is a change in acceleration.
C. Velocity is a change in speed; acceleration is a change in direction.

A. Velocity factors with speed and direction and it's kind of process of elimination from then on. Acceleration isn't a change of direction and velocity isn't a change in acceleration

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.
