g Determine which of the statements below are associated with Complex I of the electron transport chain (respiratory chain). Electrons are transferred from succinate to ubiquinone (Q). Electrons are transferred from NADH to ubiquinone (Q). Electrons are transferred from cytochrome c to O2. Electrons are transferred from ubiquinol (QH2) to cytochrome c. This complex contains 2 Cu ions. This complex contains an FMN prosthetic group. This complex contains an FAD prosthetic group. This complex contains Rieske iron-sulfur proteins. 1 and 7 1, 2, 3 and 4 2 and 7 2 and 6 2, 6 and 8 2 and 4 1 and 6

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 depends on the surface of the levels. the rougher the surface, the greater is the frictional force. for rougher surfaces, you would need to exert greater force to move the object. the concept is that, you must overcome the frictional force in order to bring the object into motion. this is the reason why we add lubricants to the joints so they could easily move. this answer was on
