Mitosis is the normal process in eukaryotes for cell division, duplicating chromosomes and segregating one of the two copies into each of the two daughter cells, and contrast with meiosis.
Dishwasher Venting Problems. Dishwasher venting problems are usually caused by a clogged vent or drain mechanism. As the dishwasher runs, water flows into the unit through the water supply and back out through the drain. To prevent the water from siphoning out of the unit during the washing cycle, air is vented from the dishwasher as water drains.
Without a vent pipe, flushing your toilet would be like trying to get all the water out of a straw with your finger held tightly to the top of the straw. It is frustrating to have leaks around the vent stacks BUT the leaking in your ceiling are not caused by rainwater flowing thru the stack vent pipe itself.
