Q: - Wind passes the turbines and moves the blades - The shaft of the turbine spins - Shaft is connected to a generator - The generator uses the spins of the shaft to rotate a rotor - The rotor spins inside the core, which has magnets inside surrounded by wire loops inside What might be the last step of the process?
A: The spinning of the rotor in the core generates electricity

Q: - Water evaporates from the ground up to the sky - Water droplets are in clouds - The air gets cold - Water droplets turn into ice crystals What might be the last step of the process?
A: Ice crystals in clouds stick together and become snowflakes.

Q: - 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

Q: - Carbon dioxide from the air passes through small pores (holes) in the leaves - These pores are called stomata - Water is absorbed by the roots and passes through vessels in the stem on its way to the leaves - Chlorophyll absorbs the sun's energy - It is this energy that is used to split water molecules into hydrogen and oxygen - Oxygen is released from the leaves into the atmosphere What might be the last step of the process?
A:
Hydrogen and carbon dioxide are used to form glucose or food for plants.
