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.
Answer:
The amount of water given to the plants depends on the effect of how tall the plant can overall grow. For instance, if all twenty identical plants are being given the same amount of water, then they will grow all at equal rates. However, if there is not equal amount/consistency with the amount of water the plants receive, then this factor may contribute to an uneven growth pattern between all twenty plants. However, other factors (such as location, sunlight, etc.) may also contribute to a plant's growth.
