<span>To figure the total magnification of an image that you are viewing through the microscope is really quite simple. To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X.</span>
Answer:
The correct answer is the third statement.
Explanation:
Alexander Fleming was a Scottish biologist, pharmacologist, and botanist. He discovered Penicillin by accident in 1928. While performing research for determining the characteristics of staphylococci, he stacked all the research jars containing staphylococci in the corner of his lab and went to enjoy the holiday with his family.
After coming back, he witnessed that some of the jars had fungus surrounding them and the majority of staphylococci got eradicated. This marked the discovery of penicillin. It was a novel kind of medicine, which exhibited a tendency to treat infections. Thus, it can be concluded that he discovered a novel kind of medicine, which could treat infections.
