Carbon dioxide is heavier than oxygen gas. It therefore displaces the oxygen gas around a flame. Without oxygen, the combustion reaction will stop and the flame will be put out.

Further Explanation:

In order for a combustion reaction to happen, three components must be present: fuel, oxygen, and heat to cause ignition. When one of these three is removed, the combustion reaction will stop.

CO2 fire extinguishers use the difference in mass of the CO2 and oxygen molecules to stop the fire. Since CO2 is heavier, it will displace any oxygen molecules that are around the flame. When this happens, the supply of the oxygen will be limited or cut-off and the fire will eventually be put out because of the lack of oxygen. This ability to displace oxygen is also what makes using CO2 as fire extinguisher quite dangerous for the user since it pushes away the oxygen that is needed for respiration.

Other ways to put out fire include spraying liquids that absorb the heat to avoid spreading the fire further or spraying substances that coat the fuel (flammable materials) to avoid contact with oxygen gas which can lead to further combustion.

Is the practice of genetically modifying human cells ethical? Why or why not?
kumpel [21]

It totally depends upon whether modification is being done in somatic cells or germ cells. Somatic cells modification is ethically accepted because it doesn't pass from one generation to another generation but germline modification is considered as unethical because the modification will pass on to the next generation leading to the persistence of modification in future generations. The problem with genetic modifications is that the impacts of modifications are unpredictable, rather than being fruitful they may lead to lethal mutations so if it occurs in just somatic cells, then even if it is lethal/harmful, it will be confined to only that individual but if a lethal mutation occurs in germ cells then it will pass on to the subsequent generations and it will persist in all future generations.

What is the role of ADH (antidiuretic hormone) in regulating salt and water concentrations in the blood?
Alisiya [41]
Right when there is not that a lot of water within the body, pituitary organ releases additional vasoconstrictor to resorb more water in the circulatory framework therefore the pee are targeted..but once there is additional water in body, less ADH can be discharged to resorb less water within the blood therefore it leads to a weaken pee.

So the answer you are looking for is B. <span>It prompts the kidneys to reabsorb more water into the bloodstream to dilute the salts.

I hope this helps!</span>
