Geographical location is the single most important factor in determining the temperature of a region.
<h3>Explanation:</h3>
The location of an area and its surrounding environment is most important in its temperature determination. As the area located near to the ocean has a low temperature. And areas which are far away from the waters and there is low precipitation which means low rain. It indicates the higher temperature areas.
Elevation of region, height from the sea level also affects the temperature of region.
The daughter cells produced from Meiosis are genetically different from each other due to the process of Crossing Over in the stage of Prophase I.
In Mitosis, there is no Crossing Over involved, since it is intended to help the body in growth and repair, not in reproduction.
Genetic Variation is important for reproduction so that not all offspring look exactly like each other or so that they do not look exactly like their parents.
It will ultimately affect every branch of the food chain, as protists are the basis of it all.
