Question

Eli5: If salt is used to cure and preserve food why is ocean water full of bacteria?

In: Biology

Answer 1

Bacteria needs water. Salt absorbs water and makes it harder for bacteria to absorb it. This is how we use salt to preserve food. But there is a lot of water in the ocean. There is not enough salt to make the oceans dry.
