A sample of food is dehydrated, which kills all of the bacteria. However, in a few days, bacteria-free water is added to the food in a bacteria-free environment. Nevertheless, microscopic investigations indicate that bacteria are in the food. How did the bacteria get there?

Answers

Answer 1

Answer:

Because the cells in the dehydrated fruit become re-hydrated with the water which then gives the cells in both the water and the fruit the tools that it needs to "come alive" if you will. And the cells become active in the fruit and use the water to grow bacteria.

Explanation:

Mercury has greater cohesion than adhesion.

What is adhesion?

The attraction between two distinct phases is known as adhesion. Adhesion cannot be explained by a single theory, however it is frequently split into two categories: mechanical interlocking and physical and chemical bonding. Adhesion often results from a mixture of the several mechanisms described below.

When two dissimilar phases only attach to one another mechanically, mechanical interlocking occurs. Typically, for the other material to penetrate, the surface needs to be a little bit rough. adhesion processes

For instance, a low viscosity glue that easily penetrates surface pores and fissures. After the adhesive has dried, this causes mechanical anchoring between the two components.

Answers

Answer:

About 12.5%

Explanation:

Every half life usually eliminates about half or 50% of drugs that is stored in the body system.

Therefore, after one half life, the percentage of drug stored in the body will be 50%, after two half lives it will be reduced by 50% which is 25%.

After three half lives, the percentage of drug stored in the body will also be eliminated by 50% which will be half of 25% and it will be 12.5%.

Therefore, the answer is 12.5%.
