What is the number of waves that go by in a certain amount of time

frequency

Explanation:

The frequency of a wave is the number of cycles the wave complete in one second. It is measured in hertz (Hz) , gigahertz (GHz) or larger scales.

Frequency F is inversely proportional to period T, which is the time it takes a wave to complete a cycle.

I.e Frequency = 1/T

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
