SOVA2 [1]

Sister chromosome exchanges are recombination events that occur between homologous chromosomes and are often the result of exposure of the cell to DNA damaging agents.
Cross over, or recombination, is the exchange of chromosome segments between non sister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.

The stomach,small intestine, esophagus or liver secretes special enzymes that help the stomach digest fats.

scZoUnD [109]

Explanation:

The stomach

Digestion describes the intake, chemical and physical breakdown, absorption of nutrients and excretion of food with the use of enzymes. The stomach secretes the enzyme, gastric lipase to digest fats.

Further Explanation:

Food is chemically and mechanically broken down into smaller particles. In the stomach the enzyme gastric lipase acts on lipids, breaking them up into their components. Phospholipids, bile acids, bilirubin, and cholesterol are combined into bile in the liver, which when secreted into the duodenum of the small intestine; this comes from its storage site, the gall bladder, and functions as an emulsifier or as a detergent.

These hold the fats and water together and increase the surface area of lipids, which can be further digested by enzymes so the nutrients are further broken down for absorption into the bloodstream.
