Translocation and internalization of AQP5 have been shown to be regulated by the phosphorylation state of the S156 residue. Researchers later isolate another residue that tends to be phosphorylated at position 259 of the AQP5 protein. If they desire to replicate the results described in the passage (S156E) with a phosphomimetic mutant construct, this construct is most likely to be:

A. T259D.
B. Y259A.
C. F259E.
D. G259W.

explanation:

ok

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
