Answer:
The United States puts more people behind bars than any other country, five times as many per capital compared with Britain or Spain.
Explanation:
It wasn't always like this. Half a century ago, relatively few people were locked up, and those inmates generally served short sentences. But 40 years ago, New York passed strict sentencing guidelines known as the "Rockefeller drug laws" — after their champion, Gov. Nelson Rockefeller — that put even low-level criminals behind bars for decades. Those tough-on-crime policies became the new normal across the country. But a new debate is under way over the effectiveness of tough sentencing laws.
Antibodies, antigens are the bad things antibodies fight :)
Answer:
Vaccines have been around since 1796 preventing people from diseases and decreasing death rates. I believe due to the modern vaccines and medicine people have been living longer than life expectancies in the 1700's and 1800’s, which was between 30 and 40 years. Vaccines train the human body to recognize viruses or bacteria and the antigens (molecule capable of inducing an immune response) will start attacking the virus or bacteria before it tries to spread and cause sickness once it is has recognized it. However, vaccines are not always 100% safe because they can come with side effects. For example, the Hepatitis B vaccine had a severe allergic reaction, called anaphylaxis which caused difficulty breathing, dizziness, and skin rashes for a few people.
