Answer:
<u>Ff</u>
Explanation:
The allele representing freckles is "f".
Heterozygous alleles have to have two different components (e.g. Ff) because the term <em>hetero</em> means<em> different</em>.
When the neuron is at rest, what is primarily responsible for moving potassium ions OUT of the cell?
a concentration gradient
an electrical gradient
both a concentration gradient and an electrical gradient
the sodium-potassium pump
Answer:
a concentration gradient
Explanation:
At rest, the sodium-potassium pumps pump the two potassium ions into the cell for three Na ions moved out of the cell. This creates a higher potassium concentration gradient inside the cell. This concentration gradient moves the K+ out of the cell. Movement of positively charged K+ out of the cells make the inside of the membrane negative with respect to the outside. This is how the negative resting potential is maintained when neurons are nor firing the action potential.
