Although computer chips are partly made of crystals manufactured in a factory by humans, why is it that these chips cannot be called minerals?

The computer chips come from semi conductive minerals usually germanium, silicon, and finding those in nature is not always easy but, they are minerals they are properly manufactured, firstly they are melted down and then are pulled into a giant single crystal that is perfectly shaped to fit the needs of the computer chip manufacturer, then they are cleaned and cut within a few thousandths of a inch usually thinner than a piece of paper and smaller than a rice grain, then etched with UV resin, washes, and copper to make microscopic pathways for transistors and so forth, then after that they are put into they're cases and have the very small like thinner than a hair small gold electrical wires attached to each point of the chip.So from a outside perspective yes they are still minerals but refined and manufactured to fit a purpose entirely different than the material itself is.

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.
