Answer: One H⁺ ion ie required in converting ATP and inorganic phosphate to ATP

Explanation:During oxidative phosphorylation, high energy electrons released by hydrogen carriers are shuttled through the electron transport chain. The released energy is used to translocate 3 H+ ions from the matrix, creating an proton motive force, which will cause 1 H+ ion to move down the electrochemical gradient and diffuse back into the matrix (chemiosmosis) which is facilitated by ATP synthase. As the H+ moves through the ATP synthase this triggers the molecular rotation of the enzyme, synthesizing ATP

kati45 [8]

Answer:

Two European men and two Polynesian women settled on a previously uninhabited tropical island.

genetic drift

Explanation:

Genetic drift entails when there are changes in the gene frequency which occur in a gene that is existing. From the analogy above, it is a known fact that only gneetic drift could allow such to happen as mutation will only occur with a sudden change of gene which is not the case described above

How does urine osmolarity compare between the two treatment groups?
larisa [96]

The urine osmolality is the measurement of urine absorption, which substantial values indicate concerted urine and small values specify weaken urine. Any foods that contained water also affects the osmolality of urine.  Some of the mammals are competent of higher osmolality than healthy humans, most especially the rats, hamsters, and mice if given no water.
