Answer:

  • by weakening the body’s immune system
  • by damaging or changing a cell's DNA

Explanation:

Tobacco contains about 60 carcinogens. The vast majority belong to three groups: 1) polycyclic aromatic hydrocarbons, 2) aromatic amines and 3) nitrosamines, the latter related to nicotine. Both tobacco and nicotine weaken the immune system of the individual, leaving him susceptible to various diseases. In addition, both tobacco and nicotine can damage or alter a cell's DNA, which can lead to cancer.

Nicotine is not a substance that directly causes cancer. However, nicotine participates in carcinogenesis by acting as an intermediary of macromolecules by its nitrosation [(bonds between nitrous groups and organic molecules), producing as a result nitrosamines (carcinogenic chemical compounds produced from nitrite and amines)] of tobacco.

<h3>Staphylococcus epidermidis: What is it? </h3>

Staphylococcus epidermidis is one of more than 40 species of the Staphylococcus genus. It is a characteristic component of human flora and is also present in marine sponges. It is most frequently detected in skin flora and less frequently in mucosal flora. It is an anaerobic facultative bacteria.

Despite the fact that S. epidermidis is typically not harmful, people with weakened immune systems are more likely to get infections. These infections are typically acquired in hospitals. S. epidermidis is known to build biofilms that grow on catheters and other surgical implants, which is why it is particularly dangerous for patients who have them. S. epidermidis is a frequent contaminant of specimens sent to the diagnostic laboratory since it is a typical component of skin flora. Some S. epidermidis strains thrive in salty environments and are frequently found there.
