The theory of spontaneous generation exclaimed that living organisms could arise from non-living matter.
Schwann affected this theory by demonstrating that fermentation required the presence of yeasts to start and that was not caused by oxygen as was speculated.
Schwann concluded by his experiments that sugar was converted to alcohol as part of an biological process based on the action of a living organism - the yeast.
While some might be familiar, nature provides us with about nine million distinct species (although only 1.5 million have been identified). Beauty is not limited to the hundreds of animals that most people can readily identify. Some fun facts will be provided about each of the ten animals.

Answer:
The 2 processes that occur in meiosis to create genetic diversity are <em>crossing over and independent assortment.</em> <em>Crossing over is when exchange of DNA segments occurs between homologous chromosomes. Independent assortment is when homologous chromosomes assort independently into gametes. </em>
Explanation:
Meiosis can be described as a process of cell division through which four daughter cells are produced having half the number of chromosomes as the parent cell.
During this process, the phenomenon of crossing over and independent assortment occurs which allows for the genetic diversity which we see in organisms of a species.
During Prophase 1 of meiosis 1, homologous chromosomes exchange segment of DNA between them which leads to genetic diversity.
During Anaphase 1 of meiosis 1, homologous chromosomes move to each side of the cell and the chances of the gamete to receive any of the chromosome is random.
