Question: -  The oxygen travels into the lungs - The oxygen binds to hemoglobin proteins within erythrocytes (red blood cells) - The erythrocytes are pumped through the body by the heart - All cells receive the oxygen.  What might be the first step of the process?
Answer: Oxygen enters the body through the mouth or nose

Please answer this: -  The sediment breaks down into small particles - Wind or water picks up the sediment - The sediment travels along the same route as the wind or water - The sediment is deposited at new locations by the wind or water - The sediment is picked up again by new wind or water - The sediment travels further - The sediment is deposited again in a new place.  What might be the first step of the process?
++++++++
Answer: Sediment settles in a place due to gravity

Problem: -  The coal powder mixes with hot air, which helps the coal burn more efficiently, and the mixture moves to the furnace - The burning coal heats water in a boiler, creating steam - Steam released from the boiler powers an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine - The spinning turbine is used to power a generator, a machine that turns mechanical energy into electric energy - This happens when magnets inside a copper coil in the generator spin - A condenser cools the steam moving through the turbine - As the steam is condensed, it turns back into water - The water returns to the boiler, and the cycle begins again -   What might be the first step of the process?

A: A machine called a pulverizer grinds the coal into a fine powder

input: Please answer the following: -  The magma cools - Crystals form and the magma become igneous rocks - The igneous rocks break down into sediment - Become sedimentary rocks - If subjected to heat and/or pressure from plate-tectonic activity the sedimentary rocks become metamorphic rock - The metamorphic rocks melt - Become magma again.  What might be the first step of the process?
++++++++++
output:
Rock begins as magma from a volcano
