Question

Match the medical discoveries with their uses.

Answer 1

The correct answer is the following.

The correct matches are:

Antibiotic: treats infections caused by bacteria.

Antiseptic: kills bacteria.

Pasteurization: makes food safer to eat.

These three elements are of the utmost importance to keep a healthy life. Since antibiotics were discovered, many people can live a longer life due to the use of them because antibiotics treat infections caused by bacteria. Before antibiotics, many people died because there was not good medicine to cure diseases. With antiseptics in soap, people can prevent many diseases when they wash their hands. And in the case of pasteurization, this process keeps some food in good condition for a period of time, allowing humans to consume it in a safer way.

Antibiotic: Treats infections caused by bacteria

Pasteurization: Makes food safer to eat 

I hope this helps :)
