uncle smiley, who is heterozygous for a yellow face, married a woman with a green face. if they were to have 12 children what is the probability that the children would have yellow faces? how many would have green faces?

hello which   of the following there is nothing!

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

sorry, but you do not have posted the diagram.
