Biology

Answer:

Explanation:

The deletion of a single base is the mutation that would most likely impair the production of a protein, because each aminoacid is coded by a triplet of three base pairs. So when one of the bases is deleted, the whole series of triplets is altered so the whole series of aminoacids in the protein would now be different.

When our bodies overcome the offensive tactics of a particular microorganism, this is referred to as? a) therapy. b) colonizatio

ikadub [295]

When our bodies overcome the offensive tactics of a particular microorganism, this is referred to as Resistance.

The body's defense against infection is provided by the immune system, a complex network of organs, cells, and proteins that also safeguards the body's own cells.

Our immune system remembers every germ (microbe) that the immune system has ever eliminated, allowing it to promptly identify and eliminate the microbe if it re-enters the body.

The body contains a number of additional mechanisms in addition to the immune system for defending itself against microorganisms, such as:

The skin acts as a waterproof barrier and secretes oil that has antibacterial qualities.

Lungs: Phlegm (mucous) in the lungs collects foreign particles, and tiny hairs (cilia) waft the phlegm upward so that it can be expelled through coughing.

digestive tract: Most germs can be killed by stomach acid and the mucous lining, which contains antibodies.

Added defenses include the anti-bacterial enzymes found in body fluids like skin oil, saliva, and tears, which can lower the chance of infection. Constant bowel and urinary tract flushing are also beneficial.
