Answer:
3)The epiglottis is a small, movable "lid" just above the larynx that prevents food and drink from entering your windpipe. But if the epiglottis becomes swollen — either from infection or from injury — the airway narrows and may become completely blocked.
4)Your stomach lining also secretes hydrochloric acid, which creates the ideal conditions for the protein-digesting enzymes to work. The potent hydrochloric acid kills bacteria, protecting your body from harmful microbes which can enter your body in food.
5)Made up of three segments -- the duodenum, jejunum, and ileum -- the small intestine is a 22-foot long muscular tube that breaks down food using enzymes released by the pancreas and bile from the liver.

<em><u>-If no oxygen is present, what process happens during cellular respiration?
</u></em>
If no oxygen is present, cells can only utilize glycolysis to make ATP. Cells without mitochondria can only utilize glycolsis. Glycolysis couples with fermentation to produce ATP. Cellular respiration is the process cells use to make energy. Cells in our body combine glucose and oxygen to make ATP and carbon dioxide. Thus why oxygen is to be present during cellular respiration.
<u><em>-Describe the process of photosynthesis. What are the products and the reactants?
</em></u>
The products is glucose, and the reactants are ATP, NADPH, co2 the of photosynthesis carbon dioxide water. These are the products of photosynthesis glucose and oxygen.
Reactants:
- Carbon dioxide
- Water
- Sunlight
Products:
- Glucose
- Oxygen
The nucleus. If a cell has a nucleus it is eukaryotic if it doesn't, it is prokaryotic.
