Problem: - Air enters bronchial tubes - Air is then split into the bronchioles of each lung - Bronchioles have alveoli which are tiny air sacs - Alveoli is surrounded by many small blood vessels - Oxygen passes through alveoli into blood vessels - Blood leaves the lungs as it travels through the body - Blood carries carbon dioxide back to the lungs - Carbon dioxide released when you exhale. What might be the first step of the process?

A: You breathe air in

Problem: Given the question: - Sediment builds up over the remains - The remains decompose, leaving only trace amounts - The remaining parts over the years are replaced with mineral - A fossil is formed - What might be the first step of the process?

input question: - This mass creates high core temperatures - The mass decreases - The red giant can no longer fuse the carbon and oxygen in its center - The gravity of the star can no longer hold the outside layers - The layers break away - Only the inner core remains - This inner core is known as a white dwarf. What might be the first step of the process????
output answer: A red giant burns mass

- The air travels into the windpipe - The windpipe divides the air to the two lungs via the bronchial tubes - The lungs oxygenate the blood in the body - Carbon dioxide is filtered out by every cell in the body - The carbon dioxide is carried back to the lungs via the bloodstream - The carbon dioxide is exhaled. What might be the first step of the process?
----
Answer: Air is taken into the body via the nose or mouth

Q: - After a rain, water seeps into cracks and pores of soil and rock - The water percolates beneath the land surface - Some of the water reaches a zone where all the cracks and pores in the rock are already filled with water - Rainwater absorbs some carbon dioxide as it passes through the atmosphere and even more as it drains through soil and decaying vegetation - The water combines chemically with the carbon dioxide - A weak carbonic acid solution is formed - This acid slowly dissolves calcite, forms solution cavities, and excavates passageways - What might be the first step of the process?
A:
Solution caves are formed in limestone and similar rocks by the action of water
