- 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?
----
Answer: The magnetic field can be turned on and off by starting or stopping the electricity source
Q: - He air we breathe contains oxygen and other gases - 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 What might be the last step of the process?
A: Your lungs and respiratory system automatically perform this vital process, called gas exchange
Question: - A bird picks a spot high spot, often in a tree - The bird collects bits of sticks and grass - The sticks and grasses are placed between support branches - Leaves, mud and spider webs are added to the sticks - The mud, leaves and webs glue the sticks together What might be the last step of the process?
Answer: The solid nest supports the eggs
[Q]: - A photovoltaic cell is created with two layers of semiconductor material - The top layer are 'doped' with impurities to allow a negative charge - The bottom layer are 'doped' to allow for a positive charge - This produces an electric field that allows electrons to flow from negative to positve - Sunlight enters the cell - Energy from sunlight knocks electrons loose in both fields - This prevents the flow of electrons from negative to positive - Adding an external circuit allows the exchange to continue What might be the last step of the process?
****
[A]: Give the cells owner a flow of electricity.
input: Please answer the following: - 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?
++++++++++
output: The oxygen can then reach the cells within the tissue
- Food enters the small intestine - The small intestine produces hormones - The hormones cause the pancreas to produce enzymes for digestion - The enzymes travel from the pancreas to the small intestine through tubes - The enzymes help the intestines digest the food - The pancreas produces the hormones insuline and glucagon What might be the last step of the process?
----
Answer:
The hormones control the amount of sugar in the blood.
