The pressure : 1.536 atm

Same container=same volume⇒the volume is constant
Gay Lussac's Law
<em>When the volume is not changed, the gas pressure in the tube is proportional to its absolute temperature </em>
![\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7BP_1%7D%7BT_1%7D%3D%5Cdfrac%7BP_2%7D%7BT_2%7D)
P₁=1 atm
T₁=20+273=293 K
T₂=450 K
the pressure :
![\tt P_2=\dfrac{P_1.T_2}{T_1}\\\\P_2=\dfrac{1\times 450}{293}=\boxed{\bold{1.536~atm}}](https://tex.z-dn.net/?f=%5Ctt%20P_2%3D%5Cdfrac%7BP_1.T_2%7D%7BT_1%7D%5C%5C%5C%5CP_2%3D%5Cdfrac%7B1%5Ctimes%20450%7D%7B293%7D%3D%5Cboxed%7B%5Cbold%7B1.536~atm%7D%7D)
A neuron has 4 basic part the dendrites the cell body
I think the answer is b.the cell body
but the brain is made up of about 86 billion nerve cells also called neuron
