According to the cladogram, which organisms are in the smallest clade with birds? mc011-1.jpg crocodiles primates rodents and rabbits sharks

The correct answer is Crocodiles

Cladograms, also sometimes called the phylogenetic trees are diagrams of evolutionary relationships between species.

These diagrams are constructed by biologists based on genetic and anatomical similarities between species.

In the cladogram of vertebrates presented below you can see that the birds and the crocodiles are placed on the same branch (clade) which indicates that they are closely related.

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.
