D). Many different experiments are performed and repeated.
Bacteria have been found to be able to detoxify certain chemicals; perhaps there are more.
<h3>What is bacteria?</h3>
Bacteria are common, primarily free-living creatures with only occasionally one biological cell. Bacterium is the singular form. They account for a large chunk of the prokaryotic microbial kingdom. The bulk of the ecosystems on Earth are home to bacteria, which are typically a few micrometers long and were among the first life forms to emerge there.
Bacteria can be found in soil, water, acidic hot springs, radioactive waste, and the deep biosphere of the Earth's crust. Bacteria play a crucial role in several stages of the nutrition cycle by recycling nutrients like nitrogen from the atmosphere. The nutrient cycle includes the breakdown of dead bodies; microorganisms are in charge of the putrefaction stage of this process.

The region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.
<h3>The normal flora of the alimentary tract</h3>
Normal flora are those microorganisms that resides in a living organism without causing it harm or diseases.
These normal flora become established in different parts of the body from birth such that the normal flora found in the mouth is not the same as the one found in the colon of the alimentary tract.
From research works, the large intestine (colon) is known to contain 100 billion per milliliter of fluid culture.
The massive numbers of bacteria in the large intestine (colon) creates a great special variation in the flora. The streptococci and lactobacilli found in the colon often adhere to cells by means of capsules surrounding the bacteria.
Therefore, the region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.

If you're talking about excel then you would select the cell with the label you want and click "Format Painter". Then, you click and drag it down the first 10 and it will automatically apply that same label to all the cells.
Answer:
