Cells need energy to carry out processes like mutation, reproduction and for mobility. The basic source of energy is glucose. If one factor prevents the cell from taking in the source of energy, then one possibility is the cell will weaken, unable to carry out processes and eventually will die.
Answer: Oxidation reaction: 
Reduction reaction: 
Overall redox reaction : 
Explanation:
Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.
Overall redox reaction :
<span>Technically, this question is badly worded. If all 4 containers were at STP, then all 4 containers would have the same pressure. So I'll assume instead that all 4 containers are at the same temperature, and then use the ideal gas law to determine the relative internal pressures of each container.
The idea gas law is
PV = nRT
where
P = Pressure
V = Volume
n = number of moles
R = Ideal gas constant
T = Absolute temperature
Since all the containers are at the same temperature, we can ignore the R and T parts of the formula and substitute some value K for constant. So we get
PV = nK
Now solve for P
PV = nK
P = nK/V
From the above, you can see that the pressure is proportional to the number of moles divided by the volume. So let's calculate that value for each container.
Container A: 0.5 / 11.2 = 0.044642857
Container B: 2 / 22.4 = 0.089285714
Container C: 1 / 22.4 = 0.044642857
Container D: 2 / 11.2 = 0.178571429
So as you can see, the pressures in containers A and C are the same, which is the first available option, so you are correct.</span>
