I believe it's D <span>.DNA repair enzymes often repair errors.
</span>I believe this because enzymes<span> remove incorrect bases with a few surrounding bases, which </span>are<span> replaced with the </span>correct<span> bases with the help of a DNA polymerase and the template DNA.

The axon, or nerve fiber, is an extension of the neuron that drives the electrical signal from the cell body to the synaptic zones. Along the axon, this signal consists of action potentials.
The other extensions of the neuron are the dendrites that lead the signal from the synapses to the cell body (to be then driven to the axon). The neurons most often have a single axon and several dendrites (the influx can come from several directions, or several dendrites, but always converge towards the axon).
Cholestrol streghtens the cell memebrane. Its STRUCTURE gets fixed in the cell membrane and then performs its FUNCTIONS that is to strengthen the cell membrane
We therefore can calculate that the total energy the sun has to burn is around 1.3 x 1044 Joules. Dividing 3.8 x 1026 Watts (the rate at which the sun is giving off energy) into this number gives an approximate value of 10 billion years for the sun's lifetime.
Answer:
Electrolytes are minerals in body fluids. They include sodium, potassium, magnesium, and chloride.
