[Q]: What is the missing first step of the following process: - Above the oven is a tank of water that is sealed - The tank of water begins to boil above the oven - A the water boils steam is created - The steam is denser than air so it needs a place to go - The steam is forced out of the tank and into a piston - The piston moves up - The valve of the piston closes - The valve on the next piston opens - The steam fills the next piston, driving it up, and the other one down -

Problem: What is the missing first step of the following process: - 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 - The carbon dioxide is exhaled out of the body.

A: You breathe in

Problem: Given the question: What is the missing first step of the following process: - Air is transported to the lungs - Air reaches the alveoli, the smallest air sacs in the lungs - In the alveoli, air passes into the blood within small capillaries - The gaseous oxygen in the air dissolves into the capillary blood - The dissolved oxygen is picked-up by red blood cells - The red blood cells bind the oxygen via a protein called heme - Red blood cells circulate throughout the body and reach the various tissues - Within small capillaries, the heme release the oxygen - The oxygen can then reach the cells within the tissue -
