Explanation: Natural gas is a limited resource. Natural gas is in the fossil fuel family and it's underground. I think it's pretty plentiful meaning that there's a lot in the United States of America. Many people use it for home heating instead of heating oil. Some people have oil trucks where the oil truck has to come and deliver oil to them.
So, natural gas is limited resource because it's a fossil fuel and it gives off emissions. It's in the ground and it's from years of decaying stuff. It's not like solar or wind power, it's a limited resource.
Answer:
Naloxone is an antagonist at opioid receptors and heroin is an agonist at opioid receptors
Explanation:
An agonist is a substance that binds to a receptor and causes a biological reaction. In this case, heroine binds to opioid receptors. An antagonist blocks the reaction from the agonist, impeding the receptor's activation. Agonists and antagonists work for specific receptors, and for an antagonist to block an agonist they must bind to the same receptor, like naloxone does with heroin. Giving an antagonist that binds to one receptor and and agonist that binds to a different one means that the antagonist will have no effect.
