In a large natural population of Mimulus guttatus, one leaf was sampled from each of a large number of plants. The leaves were crushed and subjected to gel electrophoresis. The gel was then stained for a specific enzyme, X. Six different banding patterns were observed, as shown in the accompanying diagram.

 Which one of the following conclusions is most appropriate based on the above observations?

A) There are three alleles of one locus and that the individuals with two bands are heterozygotes.

B) There are two alleles of one locus and that the individuals with two bands are heterozygotes

C) Population is present as hardy-Weinberg equilibrium

D) Population is not present as hardy-Weinberg equilibrium

In theory, auxin could increase the rate of proton extrusion by two possible mechanisms:

I) H+-ATPase activation

II) H+-ATPase synthesis

a) Auxin involves in the activation of ATP-driven proton-pump (H+-ATPase) indirectly

b) ABPs appear to be able to activate the plasma membrane H+-ATPase in the presence of auxin

c) Activity of the H+- ATPase is repressed by the C-terminal domain of the enzyme, which can block the catalytic site  in absence of auxin

d) The protein is synthesized on the rough endoplasmic reticulum and targeted via the secretory pathway to the plasma membrane

Find out the correct explanation of given mechanisms.
