Give an example of a molecule that is unable to pass through the cell membrane<br> Explain why
svet-max [94.6K]

Hello!

To answer your question:

The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others. Small molecules that are nonpolar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.

Two examples are:

Charged Ions

An ion is a molecule that is charged because it has lost or gained an electron.

Large Polar Molecules

Large uncharged molecules, such as glucose, also cannot easily permeate the cell membrane.

Hope this helps!

lions [1.4K]

Answer:

C. 0.120

Explanation:

Assortative mating by phenotype means that individuals with similar phenotypes mate with one another more frequently than would be expected under a random mating pattern. Assortative mating can increase genetic relatedness within a population.

The answer is C. 0.120 because in assortative mating, the allele frequency does not change as it is non-random mating and mates are chosen based on their phenotypes.

Alona [7]
<h2><em>EXPLANATION</em><em>:</em><em>-</em></h2>

<h3><em>Since there was already an anti resistant microorganisms that actuallly have been able to survive through the antibiotics, natural selection states that if one survives and is well adapted to a certain environment, then offspring from that survivor will be created and beneficial traits for the offspring will be received having them a chance for survival. So, the microorganisms spread and spread offspring with that anti resistance in which is the Survival of the Fittest. Until there are no microorganisms that aren’t resistant the lastahas strep throat then returns.</em></h3>
