During action potential, positively charged sodium ions move inside the cell.

So option D is correct one.

The sodium ion moves inside the cell during a action potential. The stage of action potential is called depolarization . This open voltage gated sodium channel.

Action potentials ( those electrical impulse that send signals around body ) is nothing but more than temporary shift ( from negative to positive ) in the neuron's membrane potential caused by ions suddenly flowing in and out of the neuron.

It consists of phases:

Depolarization
overshoot
repolarization

An active potential propagates along the cell membrane of an axon until it reaches the terminal button.

An ideal gas originally at 0.85 atm and 66°C was allowed to expand until its final volume, pressure and temperature were 94.0mL,

xeze [42]

Answer: The original volume in liters was 0.0707L

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 0.85 atm

$P_2$ = final pressure of gas = 456 mm Hg = 0.60 atm (760mmHg=1atm)

$V_1$ = initial volume of gas = ?

$V_2$ = final volume of gas = 94.0 ml

$T_1$ = initial temperature of gas = $66^oC=273+66=339K$

$T_2$ = final temperature of gas = $113^oF=318K$ $(32^0F=273K)$

Now put all the given values in the above equation, we get:

$\frac{0.85\times V_1}{339}=\frac{0.60\times 94.0}{318}$

$V_1=70.7ml=0.0707L$ (1L=1000ml)

Thus the original volume in liters was 0.0707L

HELP<br> How can you tell if mass is being conserved

Murljashka [212]

I can help say like gas is steaming from a pot like you cooking on the gas is being conserved after it evaporates and liquid if you drink water it’s going into your body so it’s being conserved and solid said like i have a brick and you throw it and it breaks it had been conserved because it’s broken
