Answer:
<u>ion channels</u>
Explanation:
The plasma membrane plays a critical role in regulating and maintaining ionic potential inside the cell, relative to ionic concentration present outside the cell. The ion channels are specific, in that they only recognize and allow particular ions to pass through and block the rest. Their opening and closing depends on the ionic potential during that time period.
These are the possible genotypes RR, Rr, Rr, rr
First 3 carries dominant gene for tongue rolling, so they can do it,
while the 4th genotype rr is homologous for recessive, and he/she can't
perform tongue rolling.
I believe the answers are A. C. D.
