9
Why can dehydrated food be stored for a long time without worry of it being contaminated by bacteria?
9
Dehydrated food has almost all the water removed, so bacteria cannot survive to grow and reproduce.

Why did people salt meat before refrigeration was available?
10
Salt reduces bacterial growth and reproduction.
11
When you store food for a long time, why does covering it reduce the amunt of bacterial contamination?
