Q: What is the missing first step of the following process: - 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.
A: Air enters the lungs through bronchial tubes

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 -
Answer: The human body takes a breath inward

[Q]: What is the missing first step of the following process: - Slide out the bottom rack - Take a dirty plate - Rinse the plate - Place the dish in the rack - Repeat leaving enough space for water to reach all items - Fill the soap cup - Turn on the dishwasher.
****
[A]: Open the Dishwasher

input: Please answer the following: What is the missing first step of the following process: - Once in the lungs, oxygen is moved into the bloodstream and carried through your body - At each cell in your body, oxygen is exchanged for a waste gas called carbon dioxide - Your bloodstream then carries this waste gas back to the lungs where it is removed from the blood stream and then exhaled - Your lungs and respiratory system automatically perform this vital process, called gas exchange -
++++++++++
output: He air we breathe contains oxygen and other gases

Please answer this: What is the missing first step of the following process: - Water is absorbed through roots - Chloroplast cells in leaves contain chlorophyll - Chlorophyll absorbs energy from sunlight - Energy splits water molecules into hydrogen and oxygen - Oxygen gets released into atmosphere - Hydrogen and carbon dioxide used to create glucose - Glucose is food for plants.

Answer: Carbon dioxide passes through stomata in the leaves

Question: What is the missing first step of the following process: - The coal is broken down to a smaller material - The coal particles mix with hot air and move in to a boiler - Water in the boiler is pumped and produces steam with the coal - Steam powers turbine blades, which magnetically charge wire coals - The water returns back in to its chamber and the process is repeated -
Answer:
A type of coal must be chosen before the heating can start
