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.
Tips. 1  A blocked vent in the plumbing system in your house can cause water to back out of the washing machine drain. 2  You can usually clear the vents by spraying water into the vent openings, which are on the roof. 3  You can use a drain cleaner to remove blockages from the pipes.
