Answer:
Gingivitis, Periodontitis, and Necrotizing ulcerative gingivitis.
Explanation:
Gingivitis - gums are mildly inflamed, may appear red or swollen and may bleed during brushing. Periodontitis - gums begin to separate and recede from the teeth. This allows plaque to move toward the roots, supporting fibers and bone. Necrotizing Ulcerative Gingivitis - supporting fibers, bone is destroyed and necrosis of the gum and surrounding tissue is seen.
Mitochondria...
Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.
The body defends itself against pathogens by having a line of defense. These defenses include the skin, mucus, hairs, blood clotting mechanism and, of course, white blood cells
Dear mayor.
I write this letter as a way to ask for measures for an evil that is plaguing our youth, drug abuse.
This abuse of drugs has been gradually increasing in our community and in other regions that are impacted by an insufficient economy and a flawed educational system, which has meant that young people find support only in the world of drugs.
The problem is that these substances are highly addictive, reaching the point where young people are unable to continue their lives, as they can only maintain their addiction. This opens the way for criminal and dangerous activities to be initiated, causing young people to lose their entire lives.
Therefore, I humbly ask that public policies be created to save our young people from this situation, in addition to regulatory policies for the use and sale of drugs. I believe that you will agree with the importance and urgency of this matter.
Thank you for your time.
Graciously.
M. Linn.
