Which of the following statements are correct regarding the general difference between cell and nuclear membranes? 1. A cell membrane occurs in both Eukaryotes and Prokaryotes while a Nuclear membrane occurs only in Eukaryotes.  2. Both cell membrane and nuclear membrane persists throughout the lifetime of a cell. 3. The main feature of the nuclear membrane is the presence of two lipid bilayer structures while a cell membrane has single lipid bilayer structures. Select the correct answer using the code given below.

A solid-oxide fuel cell is fed with carbon monoxide and reacts with air to produce CO2. This reaction will produce 2 electrons which are used to power an electric circuit external to the fuel cell. The reaction equation is shown below: 2CO(g) + O2(g) -> 2CO2(g) ΔHr° = -565.96 kJ/mol This reaction does not occur for other types of fuel cells which use a catalyst, such as polymerelectrolyte membrane or phosphoric-acid fuel cells. The presence of carbon monoxide on the anode side of these types of fuel cells will cause catalyst poisoning, reducing the efficiency and voltage of the fuel cell. Determine the rate of enthalpy change for a carbon dioxide production rate of 208 mol/hr. The extent of the reaction occurring in the fuel cell can be obtained by the following equation: where:
