What makes an organism’s genome the best source of data for creating a cladogram?

The Cladogram is an diagram used to represent the evolutionary relationship between the organisms.

Explanation:

Cladogram is based upon the DNA of different species of animals. It is a qualitative illustration and it doesn’t show the degree of change between the organisms.

Cladistics use the shared derived characteristics of the organisms to establish relationship between them because it is a strong proof of shared ancestry.  

To study all these features the proper data of the organism’s genome is very helpful because provides required data to draw a cladogram more effectively.

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.
