Answer:
The correct answer will be option-D
Explanation:
The Hardy-Weinberg principle was given by two different scientists Godfrey Hardy and the Wilhelm Weinberg which worked on understanding the population genetics.
The Hardy- Weinberg equilibrium is based on certain assumptions like population should have no mutations, no emigration, no selective pressure, no migration and the population should be infinite.
Since the Hardy- Weinberg equilibrium is widely used to determine the allelic frequency from the genotype therefore option-D is the correct answer.
A cell membrane completely made of a polar substance would be completely permeable to all ions present in the extracellular environment, thus disrupting unique ionic composition within the cell.
