4 Scientists want to know whether your genes or your environment has the biggest influence on your behaviour
. To answer this question they compare identical twins that were separated at birth with
identical twins who grew up together.
a Suggest why identical twins separated at birth are ideal for these studies.
b What results would you expect if inherited variation turned out to be more important than
environmental variation in determining your behaviour? Pealse short answers I dont have enogh lines

a. Identical twins who grew up together are essential for these studies so that we can see if environment is really an influence or not. Maybe it could be a different case for each one of them. So by comparing them we can know.

b. The results of inherited variation would be that the offsprings would get the same type of characteristics from their parents while environmental variation is variation causedby the environment like heat, temperature, etc.

Explanation:

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.
