There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.
Answer:
The answer is DNA replication and crossing over.
Explanation:
Both meiosis and mitosis are reproduction processes taking place in humans. But there is some difference between these two processes. In meiosis, parent cell produces four daughter cells which are not identical to each other.
In meiosis, when DNA replicates it produces four haploid daughter cells in which the number of chromosomes in half. Moreover crossing over and separation of chromosomes also occurs to produce sperms and egg cells. While in mitosis crossing over and DNA replication is absent.
The physical process that tend to change earth geological area and composition would be the plate tectonics.
