Problem: - The human body takes a breath inward - 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 What might be the last step of the process?

A: The oxygen can then reach the cells within the tissue
Problem: Given the question: - Food leaves the esophagus and enters the stomach - The stomach churns the food - With the aid of stomach acids - The food becomes a thick liquid What might be the last step of the process?
++++++++++++++++++++++++++++++++
The answer is:
Is then passed to the small intestine.
input question: - Greenhouse gases are released into the air by human activities - The earth changes energy from the sun into heat - Heat rises from the ground - Greenhouse gas molecules in the atmosphere prevent the heat from going into space - The temperature of the earth increases - The temperature continues to rise and melts the polar ice caps What might be the last step of the process????
output answer: The temperature rises even faster.
- Water from the surface seeps below the soil - The water comes into contact with the rock below - The rock over the years carves through the rock - The space in the rock becomes larger and forms into a cave What might be the last step of the process?
----
Answer: As more rather rushes through the cave becomes a cavern.
Q: - Animals eat a lot during good (warm, clear) weather - Animals gain weight - The season changes to one with bad (cold, snowy) weather - Animals find a place to hibernate - Animals enter a type of 'sleep' (hibernation) - Body processes slow down - The animal's heart rate and breathing rate slow - The animal loses weight more slowly than usual What might be the last step of the process?
A: The animal is able to survive not eating or drinking without hurting itself
[Q]: - A conducting metal, like copper, is wrapped around a piece of metal - An electrical source, like a battery, produces an electrical current - The electrical current flows through the wire - The electrical current creates a magnetic field around the wire, magnetizing the metal What might be the last step of the process?
****
[A]:
The magnetic field can be turned on and off by starting or stopping the electricity source
