Answer:
A. in order to release the energy found in food.
Explanation:
Every cell in your body needs oxygen to function. You get the oxygen your cells need from the air you breathe. The air you breathe is made up of 20 percent oxygen. The rest of the air is mostly nitrogen (79%). Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs. This is very similar to wood burning in a fire. As the wood burns, it combines with oxygen and releases heat energy and carbon dioxide. When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released. But instead of heat energy, much of the energy produced in cellular respiration is stored chemically for the cell to use later. Carbon dioxide is the waste product of cellular respiration that you breathe out each time you breathe. Blood picks up oxygen and releases carbon dioxide in the lungs. The opposite takes place in the cells where the blood releases oxygen and picks up carbon dioxide.
6H2O+6CO2=C6H12O6+O2
there are six water and carbon dioxide molecules reacting to give glucose (C6H12O6) and oxygen (O2) note#except for the two sixes in front of carbon dioxide and water the other numbers are written in subscript(below the letters)
Answer:
Answer is A, the slowed activity of the nasal cilia.
Explanation:
The nasal cilia are hair-like structure or projection. which are found in the mucus membrane. The germ , dust or particles that could cause irritation to the lung, are captured by the mucus. This mucus are moved away from the lung by the nasal cilia, either through the nose or swallow.
They can also be found at the air passage , moving mucus out of the lung.
In the case of the little girl, the girl experienced a running nose due to the slow activity of the nasal cilia, this is because of the col temperature.
Pharynx --> Larynx --> Trachea --> Bronchi
Larynx is part of the Pharynx, and the trachea is located in your throat, and the bronchi with your lungs.
