A gas piston is a system that is used in the generators to produce energy. With the change in the volume of the piston at the constant pressure, the energy in joules is, 266.49 J.
<h3>What is energy?</h3>
The energy of the system is given by the negative product of the pressure and the change in the volume.
Given,
Pressure = 2.12 atm
Initial volume = 0.260 L
Final volume = 1.50 L
Energy = -PΔV
= - (2.12) (1.24)
= - 2.63 L. atm
Converting the units:
1 L atm = 101.325 J
-2.63 L atm = 266.49 J
Therefore, 266.49 J is the energy.

Answer:
Domain Eukarya have cells with a nucleus.
The Eukarya differ from the Archea and Bacteria in that their cells are eukaryotic, meaning they contain a membrane enclosed nucleus and other membrane enclosed organelles.
Multiple sclerosis is a condition where the myelin sheath hardens; disrupts the flow of information through the neurons. Myelin sheath is a layer of fatty cells which helps in the transmission of nerves impulses along the axon by insulating it. It is an outgrowth of a type of glial cell which is formed by a process called myelination or myelinogenesis.
Therefore, the correct answer is Myelin sheath.
