[Q]: What is the missing first step of the following process: - As the saltwater is heated the water becomes a gas - The salt particles sink to the bottom of the container - Gaseous water is piped into another container - Allowed to cool - The salt particles are left behind in the first container - The second container contains fresh water.
****
[A]: The salt water is heated

input: Please answer the following: What is the missing first step of the following process: - You fill the tray with warm water - You carefully place the tray on an even surface in a freezer that is at least 32 degree Farhenheit, the freezing point of water - The water begins to get colder until it starts to freeze solid - The water expands as it freezes, one of the few liquids that has greater volume as a solid - Because you used warm water, the gasses in the water had evaporated out, so you will have nice clear ice cubes without cracks from the trapped gasses -
++++++++++
output: You find an empty ice cube tray

Please answer this: What is the missing first step of the following process: - Air goes through all the little branches in your lungs to fill up the air sacs, or alveoli - Oxygen goes through the walls of the alveoli and into the capillaries - The oxygen goes into the bloodstream - Oxygen is left and carbon dioxide is picked up - You breathe it out through your lungs -
++++++++
Answer: You breathe in

Problem: What is the missing first step of the following process: - The lungs have a series of smaller and finer tubes and sacs - Air reaches the smallest and finest air sacs called alveoli - Oxygen travels from the alveoli into the blood - Oxygen-rich blood is carried to the heart - Oxygen-rich blood is pumped throughout the body by the heart - Cells take in the oxygen rich blood and release carbon dioxide rich blood - The carbon dioxide rich blood travels to the lungs - Carbon dioxide travels through the throat and is exhaled.

A: Air enters the nose or mouth and travels through the windpipe into the lungs

Problem: Given the question: What is the missing first step of the following process: - The rocky area has a higher elevation than the surrounding areas - Water from precipitation falls in the area - The water forms a stream - The stream flows towards lower elevation - The stream becomes a river - The river continues to flow along the same path for a long time - The river erodes the rocky area that it touches - The eroded area cuts deeply into the rock.
++++++++++++++++++++++++++++++++
The answer is:
A large rocky area is formed

Problem: What is the missing first step of the following process: - The oxygen travels into the body - Breaks down into glucose - Carbon dioxide is produced by the glucose breakdown - The carbon dioxide is exhaled out of the body through the nose or mouth.

A:
A person takes in oxygen through their nose or mouth
