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.
An air gap for a dishwasher is a requirement set forth by local plumbing codes. It is a device designed to ensure water flows only in the right direction during the dishwasher cycle. As a dishwasher operates, hot water flows in from the sink's hot water connection.
