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.
They are based on their temperature and precipitation according to the <span>Köppen Climate Classification System</span>
<span>It produces progesterone.The ovaries produce the female hormones estrogen and progesterone, in addition to a minute quantity of testosterone. Each ovary has thousands of follicles competent of generating eggs for fertilization. The brain cause the ovaries to develop a single mature egg cell for potential fertilization.</span>
Answer: The length of the cell in millimetres is 0.0015.
Explanation:
Given conversion :
Thus 
Given : Length of the cell = 1.5 micrometers 
To find: Length of the cell in milllimeters (mm)
Length of the cell in milllimeters (mm) = 
The length of the cell in millimetres is 0.0015.
Answer:
option a
Explanation:
because When hydrogen is used to power a fuel cell, the only byproducts are water and heat—no pollutants or greenhouse gases are produced.
