Bacterial cells can generate antibiotic resistance by two preferred method: first is via mutations that happen while replication in the cell's DNA and second is bacteria achieve tolerance by horizontal transmission of genes. Few bacteria have sufficient immune and naturally due to an extremely impermeable cell membrane or absence of target that is selected by the antibiotics. Other bacteria may produce enzymes which may inactivate antibiotics on having any communication.
In certain cases, bacteria may alter the target of the antibiotic, making the antibiotic unsuccessful. The organic protection of the body are extremely successful in fighting off such oral infections and in controlling inflammation. The study found that antibiotics killed the favorable bacteria, which reduced the development of SCFAs (short chain fatty acids) and impaired the capacity of white blood cells to combat fungal infections, like Candida.

Answer: Measuring the amounts of radioactive elements in rocks let scientists useabsolute dating to give ages to each chunk of time on the geologic time scale. For example, they are now able to state that the Jurassic began about 200 million years ago and that it lasted for about 55 million years.
Explanation:
Answer:
Cells from the pure culture can cause disease in healthy individual after infecting it with the pure culture.
Explanation:
Koch postulates says that microbes are the cause of every disease. These microbes can be isolated from the infected host and can be grown outside the host in a pure culture. Then this pure culture is able to cause disease in a healthy host after infecting the host with pure culture. Then this same microbe can again be isolated from the second host.
So Koch postulates which proves that cells from the pure culture can cause disease in healthy individuals after infecting it with the pure culture was the step that enabled Koch to determine that a particular microbe is the cause of the disease because it was causing disease in healthy individual also.
