<h2>Koch's Postulates.</h2>
Explanation:
The next step should be isolate the microorganism from the mice and check if it is identical to the original microbe.
According to Koch's postulates, a microbe can be considered as a causative agent of a disease only after all the following are established:
- The microorganism should be present in all the organism suffering from the disease.
- The isolated microorganism should be grown in pure culture.
- The organism grown in the culture should be reintroduced in the susceptible but healthy host.
- Finally the microorganism must be re-isolated from the experimental host an cultured to see whether it is identical to the original specific microorganism.
 
        
        
        
Answer:
The interpretation including its set of circumstances is characterized throughout the explanation segment below.
Explanation:
- Lakes that always collect a significant amount of acid rain can also have water with either a pH value very low than 4. (the latter indicates that low pH levels are much more acidic versus significantly higher.) 
- The world's oceans are covered from ocean acidification by limestone formations, which serves as a barrier to neutralize acid rain.

The correct answer is  detailed structure inside the cell.
The main feature of compound light microscope is the light source which helps to see the objects more clearly. This microscope is usually used to see the detailed structure inside the cell. The cell organelles are clearly visible that are very minute in size and cannot be seen through naked eyes. This allows us to study the features of the cell more accurately and precisely.
