Answer:
Jonas Salk was awarded the Nobel Prize for discovering a way to vaccinate against polio in the United States in the 1950's. This allowed millions of school-age children to avoid crippling disease, and to swim during summer again, as polio was often spread in public swimming areas before.
The statement that best describes how the polio vaccine works is:
It triggers the immune system to produce antobodies to fight the disease-causing agent.
Explanation:
There are two main reasons for this answer. The first one is that every vaccine is aimed to introduce a controlled amount of antigenes to be accepted by the organism. These antigens are made after some studies were conducted in a lab and were obtained from substances that the human body can accept to train the immune system to develop an effective defense for the virus or bacteria on the matter. In our case, the polio vaccine works the same way and allowed to save many lives.
Taking multiple antibiotics at the same time contributes to antibiotic resistance. Thus, the correct option is B.
<h3>What is Antibiotic resistance?</h3>
Antibiotic resistance may be defined as a process or strategy of microorganisms that generate the capability to conquer the drugs developed to annihilate them.
Overprescription of multiple antibiotics increases the ability of bacteria or other microorganisms to survive in harsh little conditions. Still, slowly they evolve themselves and resist the situation of the high effect of antibiotic resistance drugs.
Therefore, it is well described above.

The correct answer s act late in the disease.
Disease:
- When tumor DNA is studied from cancer patients at various stages, the mutation will be comparable in all of them. Tumor DNA is frequently identified in the blood stream.
- Disease is any adverse variation from an organism's normal structural or functional condition that is typically accompanied by a set of symptoms and is distinct from physical injury in origin.
- illnesses. An abnormal state of an organism that interferes with its normal bodily functioning, frequently causes pain and weakness, and is typically accompanied by symptoms and indicators.
- Disorders produced by organisms, infectious diseases are those caused by microorganisms such bacteria, viruses, fungi, or parasites. Numerous species live inside of our bodies. They are generally advantageous or even secure. But in specific circumstances, some bacteria have the capacity to cause disease.
