What is the role of enzymes inside a lysosome? a) they send signals to other parts of the cell. b) they move molecules to other parts of the cell. c) they break down large molecules. d) they form sacs from other membranes.

C. Lysosomes, otherwise known as the suicide sac, digests other molecules. It’s known as the suicide sac because if it digests too much in an attempt to clean the cell, it will explode.

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.
