Answer:

Explanation:

Mitosis occurs after interphase (which is the phase that takes the longest) and is occurring all the time in your cells. Sometimes a cell will not go into a state of mitosis if an error is found during the interphase process (if it does, it's cancerous) . Some cells don't go through the process of mitosis, like neurons. But once a cell passes interphase without any errors, it will go into mitosis then cytokinesis. The process takes about one day and occurs when your body is repairing itself or if you're growing and developing. So yes, it happens all the time, just not in every single cell; just in most cells.
