Question

Match these vocabulary words with their definitions.

1 . bacteria process of heating a substance to kill harmful microbes but leave the flavor unharmed
2 . microscopic substances of dead or weak bacteria introduced into the body to produce resistance to a specific disease
3 . vaccines easily transferred from person to person by direct or indirect contact; catching
4 . germ chemical that slows down or stops bacterial growth
5 . antiseptic microscopic organism (microbe)
6 . pasteurization microscopic organism which does not have a nucleus and multiplies by simple cell division
7 . contagious requiring a microscope to view due to very small size

Answer 1

1. bacteria: microscopic organism which does not have a nucleus and multiplies by simple cell division

2. microscopic: requiring a microscope to view due to very small size

3. vaccines: substances of dead or weak bacteria introduced into the body to produce resistance to a specific disease

4. germ: microscopic organism (microbe)

5. antiseptic: chemical that slows down or stops bacterial growth

6. pasteurization: process of heating a substance to kill harmful microbes but leave the flavor unharmed

7. contagious: easily transferred from person to person by direct or indirect contact; catching

Step-by-step explanation:

Bacteria are microscopic organisms which donot have nucleus and multiplies by simple cell division

When something is microscopic, it can hardly be seen without using a microscope due to its very small size

Vaccines are substances of dead or weak bacteria introduced into the body to produce resistance to a specific disease

Germs are microscopic organisms or microbes

Antiseptics are chemicals that slow down or stop bacterial growth

Pasteurization is a process of heating a substance to kill harmful microbes but leave the flavor unharmed

When something (usually a disease) is contagious, it means such disease can easily be transferred from person to person by direct or indirect contact.
