How yall have so many points :((

Aneuron is stimulated with an electric pulse. the action potential is detected at a point 3.70 cm down the axon 0.0052 s later.when the action potential is detected 7.20 cm from the point of stimulation, the time required is 0.0063 s. what is the speed of the electric pulse along the axon? (why are two measurements needed instead of only one? )

Are the earth's ocean floor and continents the same age geologically? why or why not?

During the process of two rails or sides break apart and attract new nucleotide bases to form a new and complete strand.
