Answer 1

Answer:

$answer \: 1)$

Antibiotics and vaccines are in some ways opposites. Antibiotics kill indiscriminately, whereas vaccines are highly targeted. Antibiotics are used to treat severe infection, whereas vaccines prevent infections from ever becoming established. And antibiotics are based on defenses that evolved in microbes, to protect them from bacteria; they are not a natural defense for us, and our bodies are not adapted to cope well with them. Vaccines, in contrast, simply invoke the human body’s natural long-term defense systems, and are therefore far less invasive.

Explanation:

Pasteurization or pasteurisation is a process in which packaged and non-packaged foods (such as milk and fruit juice) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life.
