Answer:
B. Fossil fuels are nonrenewable and may cause pollution.
Explanation:
Fossil fuels are nonrenewable, meaning that they cannot be replenished sustainably. So, eventually, we will run out of them because they cannot be renewed.
Another disadvantage of fossil fuels is that they cause pollution. For example, the gasoline that is used by cars creates significant amounts of pollution every year.
Pollution is created by cars, factories, homes, and everything else that uses fossil fuels.
So, the correct answer is B, fossil fuels are nonrenewable and may cause pollution
Answer:
Carbon monoxide.
Explanation:
Carbon monoxide is a gas that consists of an oxygen and a carbon to be able to fulfill the complete molecule, it is a potentially dangerous gas for life on this earth.
On the other hand, what differentiates it from carbon dioxide is that it has two oxygens that are coupled with a carbon to fulfill the complete molecule.
Both gases are pollutants, and produced by man, it is considered that these in high partial pressures in the atmosphere generate a mortal potential for humans since they have more affinity with the hemoglobin protein that is the human gas transporter par excellence, the which oxygenates the tissues.
If the oxygen drops in partial pressure and these toxic gases increase, the hemoglobin having a higher affinity will bind to them and toxify the human body, preventing oxygenation.
