A rather large population of sheep consists of 418 white sheep and 732 black sheep. Assume that white is totally recessive. Please calculate the following (p, q,p-squared, q-squared, and 2pq)

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.

the answer is c. it will give up it's valence electron to the other atom.

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
