Answer: E) provide the defense for the CNS
Explanation:
Astrocytes can be defined as one of the cell types in the central nervous system. These are the dominant glial cell found in the brain. These cells perform a variety of functions in the brain. The functions includes axon guidance, synaptic support, controlling the blood brain barrier and blood flow. These cells maintain the chemical environment in the brain especially around the neuron.
These cells do not provide to the central nervous system.

Plasmid is mostly found in bacterial cell, but few can be found in animal cells
Phosphoryl-transfer potential is the ability of an organic molecule to transfer its terminal phosphoryl group to water which is an acceptor molecule. It is the “standard free energy of hydrolysis”.
Explanation:
This potential plays a key role during cellular energy transformation by energy coupling during ATP hydrolysis.
A compound with a high phosphoryl-transfer potential has the increased ability to couple the carbon oxidation with ATP synthesis and can accelerate cellular energy transformation.
A compound with a high phosphoryl-transfer potential can readily donate its terminal phosphate group; whereas, a compound with a low has a lesser ability to donate its phosphate group.
ATP molecules have a high phosphoryl transfer potential due to its structure, resonance stabilization, high entropy, electrostatic repulsion and stabilization by hydration. Compounds like creatine phosphate, phosphoenolpyruvate also have high phosphoryl-transfer potential.
Moon, Venus and Mars are the closest.
