Answer:
The correct answer is option C.
Explanation:
The human gastrointestinal microbiota or the gut microbiota or the gut flora refers to the microbes, which thrive in the digestive tracts of humans. The human gastrointestinal tract comprises the gathering of all the genomes of gut microbiota. It is the niche where the human microbiota is found.
The microbial composition of the gut microbiota differs across the digestive tract. In the small intestine and stomach, very small species of bacteria are found, while the colon comprises the densely populated microbial ecosystem. Of these over 99 percent of the bacteria found in the gut are anaerobes, as the space within the intestines is highly anaerobic.
These microbes are confined deep within the body where oxygen cannot reach as it is not supplied with the help of blood vessels. Thus, a highly anaerobic environment is witnessed deep within the intestinal regions.
Well... I get the felling I know what question you are trying to ask. Atrial Fibrillation is a type of arrhythmia that interferes with the pumping of blood through the Atrium of the heart. A bundle branch block is an interference of the electrical system through the heart. Non of these are particularly that dangerousso don't worry about dying... Though have someone close by in case you go into Cardiac Arrest.
If your worried about getting a heart attack, that is a blood flow problem which can result from CAD. Don't worry though cause the two other condition do not particularly influence the other.
CAD is circulatory, A fib and branch block are electrical.
A basic definition of an ionic compound is that they are molecules that consist of charged ions. These ions have opposite (both negative and positive) charges. On the other hand, covalent compounds are non-metals which are bound together, and consist of two electrons that are shared between two atoms.
