When rocks are analyzed over an increasingly greater distance from a mid ocean ridge what can be said about the polarities of the rocks? a. they are constant b. they alternate once c. they alternate multiple times

The answer is C. They alternate multiple times.

C. They alternate multiple times

Explanation:

When rocks are analyzed over an increasingly greater distance from a mid ocean ridge the polarities of the rocks alternate multiples times. Rocks and minerals record  orientation of magnetic field of the Earth since the time they solidify. Periods when the north magnetic pole is located near Earth's South Pole are called reversed polarity.

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
