Enzymes are proteins that are capable to speed up a chemical reaction acting as catalysts.
Answer:
1. The correct answer would be A) allow you to view living cells, while electron microscopes do not.
There are many advantages of light microscope over electron microscope such as:
- It is easy to use as compared to the electron microscope.
- It enables us to view both alive as well as dead specimen whereas electron microscope can be used to view dead specimen only.
- Light microscopes are much cheaper and have much lower maintenance cost as compared to the electron microscope.
2. The correct answer would be C) scanning electron microscope
Scanning electron microscope or SEM is a type of electron microscope which is used to observe surface topography and composition of the specimen. It can achieve resolution of up to 1 nanometer.
3. The correct answer would be 400x
The total magnification of the microscope can be calculated by multiplying the powers of the objective lens and that of the eye lens.
Thus, the magnification of the specimen would be 40*10 = 400x.
