Mitosis happens in all types of cells. in this division, the cell will double it's number of chromosomes and then will be divided into two separated cells. so the number of chromosomes in product is equal to the number of chromosomes of the first cell
but meiosis only happens to produce gametes. the cell will be divided into two separated gametes.
in this division the number of chromosomes won't be doubled. so gametes have the half number of a normal person chromosomes.
good luck

Explanation:
In a lake, oxygenic phototrophs produce new organic material as well as O₂. If primary production rates are very high, the resultant excessive organic matter production can lead to bottom-water O₂ depletion from respiration and the development of anoxic conditions. This in turn stimulates anaerobic metabolisms, including anaerobic respirations and fermentations.
Organic matter that is not consumed in surface layers sinks to the depths and is decomposed by anaerobes.

The largest dna fragments are located near the top of the gel. (Negative electrode, where they began)
