Summarize how seafloor spreading to explain the continental drift hypothesis

When the sea floor spreads it moves the continental plates. For example, the mid-Atlantic ridge pulls apart and very little subduction zones are around it, pushing the North American plate and European plate apart expanding the Atlantic and shrinking the pacific.

Cell division is important to single celled organisms because it allows the cells to reproduce. through cell division, cells make exact copies of themselves. when single celled organisms go through cell division, they make exact copies of themselves which is how they reproduce.
