Problem: What is the final step of the following process: - You breathe in - Diaphragm and other muscles expand to allow room for your lungs to fill - The air flows into the narrow bronchioles in the lungs - From the bronchioles to the alveoli - The oxygen enters into the bloodstream - Is switched with the carbon dioxide in the bloodstream - The carbon dioxide enters through the alveoli - Through the narrow bronchioles - Into the lungs

A: The carbon dioxide is exhaled out of the body.

What is the final step of the following process: - A photovoltaic cell is created with two layers of semiconductor material - The top layer are 'doped' with impurities to allow a negative charge - The bottom layer are 'doped' to allow for a positive charge - This produces an electric field that allows electrons to flow from negative to positve - Sunlight enters the cell - Energy from sunlight knocks electrons loose in both fields - This prevents the flow of electrons from negative to positive - Adding an external circuit allows the exchange to continue
----
Answer: Give the cells owner a flow of electricity.

Q: What is the final step of the following process: - Air is brought in through the mouth - Passes through the lungs - And into the bronchial tissue - The carbon dioxide is removed
A: The lungs bring the oxygen to the rest of the body.

[Q]: What is the final step of the following process: - Dead organic material accumulates on the bottom of oceans, riverbeds or swamps, mixing with mud and sand - Over time, more sediment piles on top - The resulting heat and pressure transforms the organic layer into a dark and waxy substance known as kerogen - Left alone, the kerogen molecules eventually crack - The molecules break up into shorter and lighter molecules composed almost solely of carbon and hydrogen atoms
