Exocrine pancreatic insufficiency (EPI) causes problems in how you digest food. Your pancreas doesn't make enough of the enzymes that your body needs to break down and absorb nutrients. Enzymes speed up chemical reactions in your body. The enzymes made by your pancreas move into your small intestine, where they help break down the food you eat. When you have EPI, you don't get the nutrition you need because your body can't absorb fats and some vitamins and minerals from foods. You might lose weight or have pain in your belly.
Genetic variety in organisms is created through C) Meiosis. mitosis is a stage of the cell cycle and asexual reproduction occurs between only one parent, so not much variety. Cell fission is a form of asexual reproduction in bacteria, archaea, and other unicellular organisms such as diatoms and protozoans.
Without reproducing biodiversity will decline dramatically because all species' would go extinct.
