Scientists cite evidence that Earth's climate has been changing significantly over the past 50 years. They also argue that changes to Earth's orbital path are NOT the cause of these significant changes to climate.
Which statement provides the STRONGEST evidence in support of the scientists' argument?
A. Variations in Earth's orbital path are consistent with accepted laws of planetary motion.
B. Earth's orbital path does not affect the amount of solar energy that Earth receives.
C. Changes to Earth's orbital path occur in a cycle that repeats every 100,000 years.
D. Climate change cannot be demonstrated over a span of 50 years.

Molecules called lipids have long hydrocarbon chains that determine the way they act. they can be fats, oils, or hormones, and even exist in our cell membranes 

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. 

It would be like the 70's song "it's raining men".
