What is the likely advantage of growing a genetically modified variety of corn that possesses its own pesticide? The shelf life and sale of corn would increase. It is more efficient and economical to grow this variety. When consumed it offers more nutrients than the regular variety. When consumed it improves the quality of life of people with genetic disorders.

Explanation:

As one who has suffered health problems for more than 40 years due to the desire of certain chemical industries to make money by polluting my food, I can barely remain civil when discussing genetic modification. Plants with built-in pesticides are bad news on so many levels it would take a library of books to discuss them all. What, after all, is the benefit of efficiently producing poison?

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 denominator has a very specific role.
