Many essential nutrients are transported into plant cells through cotransport with H­+, which flows back into the cytoplasm. Proton pumps in the cell membrane of plant cells actively pump H+ into the extracellular space using energy from ATP hydrolysis. If a toxin that inhibits the plant proton pump is applied, which of the following would be true?

The sodium-potassium pump would cease to operate.
There would be more potential energy outside the cell than inside.
The electrochemical gradient across the cell membrane would be depolarized.
The cotransport of solutes against their concentration gradients would be enhanced.

It is platinum in the market value

What is the question? if you were looking to design a method of separating something, you can separate this compound by putting both in water and allowing the water to dissolve the sugar. then pour it into another beaker and evaporate it then boom! salt and sugar : ) 

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.
