what causes the second voltage-gated Na⁺ channel to open is that after the first channel opens, the movement of many types of ions (both inside and outside the cell) alters the distribution of charges near the second channel, causing it to open. Option D
Voltage-gated sodium channels are known as transmembrane proteins that cause rapid depolarization resulting to upstroke of action potentials in neurons and are thus important to nerve impulse conduction.
Our nervous system contains cells, the neurons that send information to and from the brain and spinal cord .
Sensory nerves receive stimuli from receptors by a change in voltage or membrane potential that occurs across the plasma membrane.This voltage difference is determined by the relative concentration of potassium and sodium ions inside compared with outside of the nerve cell. Hope this helps. Thanks
From the information given, the original volume of the gas is 300ml at 17 degrees Celsius. The final volume at 10 degrees Celsius is unknown.
To find the final volume of the gas, we need to apply Charles law which is expressed as V1/T1 =V2/T2
Where V1 original volume
where T1 is orginal temperature
where V2 is final volume
where T2 is final temperatue
We need V2 so V2 = (V1 × T2) ÷ T1
V2 = 300 × 10 ÷ 17
V2 = 400 ÷ 17
V2 = 23.52
Volume at 10° C is 23.52 ml
