Explain why ions do not move through ion channels by only simple diffusion, whereas water does move through water channels by si

mple diffusion.
Specifically, what, in addition to the concentration gradient, affects the movement of ions through ion channels?

Answer:

Electrical gradient.

Explanation:

Ions DO NOT move in Ion channels by simple diffusion because most ion channels can be:

I) selective of ions pass through it.

II) operating on a "open and close" principle. Where it opens or close on its own accord OR does so ONLY when induced by a specific influence like change in voltage of ion channels.

IN ADDITION to the concentration gradient, ELECTRICAL GRADIENTS (change in membrane voltage) affects the movement of ions through ion channels

Differentiate between density-dependent and
Setler [38]

Answer/Explanation:

Density-dependent limiting factors are non living and biotic factors that affect the size and growth of a population based on the population density, while density-independent limiting factors are those factors that do not depend on the density of a population before they can have an effect on the growth and size of the population.

Examples of density-dependent limiting factors are predation, disease, Parasitism, competition. These rely on the density of a population in order to affect the growth and size of a population.

On the other hand, examples of density-independent limiting factors are pollution, flood, temperature.

What can we say about the frequency of x-linked recessive traits?
ohaa [14]
What we can say about the frequency of x-linked recessive traits is that the frequency of the allele for the recessive x-linked traits is assumed to be equal to the proportion of males with the recessive phenotype.

A population of skunks lives in a woodland habitat. The skunks are unable to leave because of a large mountain. Describe two rea
ohaa [14]

Some of the conditions that must be met for a population or an allele to be in Hardy-Weinberg equilibrium are:

1. The population must be very large.

2. There must be no migration and population must be isolated.

3. There must be no mutations.

4. There must be random mating, which means there are no mating preferences.


So, a population will not be at Hardy-Weinberg Equilibrium if it is small, or there are mutations, which is not mentioned, but mutations are expected to occur. Also, although there is a large mountain, skunks can migrate to some other area of a woodland. So, probable mutations and migrations suggest that the population is not at <span>Hardy-Weinberg Equilibrium.</span>
