[Q]: - Air enters bronchioles - Bronchioles have tiny air sacs called alveoli - Alveoli surrounded by small blood vessels - Oxygen absorbed by small blood vessels - Vessels deliver oxygen to every cell in the body - Blood brings carbon dioxide back to lungs - Carbon dioxide released when you exhale. What might be the first step of the process?
****
[A]: Air enters the lungs through bronchial tubes

[Q]: - Waves have energy that pushes the water and sediment - The sediment can help erode land like sandpaper - Water washes the sediment back - Some sediment is left as sand. What might be the first step of the process?
****
[A]: Waves hit the coast

[Q]: - 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. What might be the first step of the process?
****
[A]: You breathe in

[Q]: - The spore lands on a piece of bread - The spore grows hyphae into the bread - The mold forms a colony - Sporangiophores grow upward - The mold sends out spores. What might be the first step of the process?
