Jonas Salk was awarded the Nobel Prize for discovering a way to vaccinate against
Bogdan [553]

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.

Why does ice become less dense than water?
myrzilka [38]
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.
