1. The correct answer is "Respiration".

To determine the correct answer, let's break down the options and see which one matches the given explanation. The question states that the chemical reaction in cells needs oxygen to release energy and produces carbon dioxide and water as waste. Breathing, exhaling, and inhaling are all related to the process of respiration, but none of them accurately describe the chemical reaction that occurs in cells. Respiration, on the other hand, perfectly fits the description as it involves the release of energy with the use of oxygen and the production of carbon dioxide and water as byproducts.

2. The correct answer is "alveoli; capillaries".

To find the correct answer, we need to understand the structure and function of the lungs. Lungs consist of tiny sacs called alveoli, which are responsible for the exchange of oxygen and carbon dioxide. These alveoli are surrounded by a network of tiny blood vessels called capillaries. Oxygen from the air enters the alveoli and diffuses into the capillaries, while carbon dioxide from the blood diffuses into the alveoli to be exhaled.

3. The correct answer is "Pharynx, larynx, trachea, bronchi, alveoli; diaphragm".

To determine the correct answer, we need to understand the sequence of air flow through the respiratory system and its relation to the diaphragm. As air enters the respiratory system, it passes through the pharynx (throat), then the larynx (voice box). From there, it travels down the trachea (windpipe) and branches into the bronchi, which are the main air passages leading to the lungs. Finally, the air reaches the alveoli, where gas exchange takes place. The diaphragm, a muscle located beneath the lungs, helps with the process of breathing by contracting and relaxing to expand and contract the lungs, allowing air to flow in and out.

By analyzing the given options, we can see that "Pharynx, larynx, trachea, bronchi, alveoli; diaphragm" is the correct sequence of air flow through the respiratory system, which is powered by the diaphragm.
