Answer:
It means that the cell membrane allows certain substances to pass through and not others. As the cell membrane consists of a phospholipid bilayer with a hydrophobic core, only small uncharged hydrophobic molecules can pass through the cell membrane e.g. glucocorticoid and other larger charged particles require transporters or channel proteins to pass through the cell membrane, e.g. glucose.

To conclude, you cannot prove a hypothesis because you can never generalise the results to the whole population and foresee the results will always be the same in the future. You can however, reject the null hypothesis consistently, through statistical hypothesis testing so that the theory becomes highly likely to be true, but not proven.

Another is that a large number of progenies are produced with asexual reproduction but a limited number of progenies are produced with sexual.
