At rest, potassium (K+) ions can move across the cell membrane easily.

At rest, chloride (Cl-) and sodium (Na+) ions cannot move across the membrane easily.

Negatively charged protein molecules that are inside the neuron cannot cross the membrane.

The total difference in voltage between the inside and outside of the cell at rest is negative.

Eyelash length is an inherited trait. in the human population, there is an eyelash length gene. there are two possible variants

VMariaS [17]

Humans, like all mammals, are diploid organisms. This means that we have two copies of each chromosome. In diploid organisms, one somatic cell would have two copies of each gene. This means that in one somatic cell, an individual carries two copies of alleles for long eyelashes, and also two copies of alleles for short eyelashes.
