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.
The overall biodiversity in the Gulf of Mexico has gone down since the Deepwater Horizon spill. I hope this helps.

According to the Dietary guidelines for
America, men aged 19 and older should
consume an average of 2.640 calories and
women should consume an average of 1.785.
However, these numbers may vary according
to each person and their way of living. Some
bodies will need more than that and some
other less. that would depend on physical
activities and work among other things.
