  1. An advantage of light microscopes compared to electron microscopes is that light microscopes A)allow you to view living cells, while electron microscopes do not. B)allow you to view the surface of cells in greater detail than electron microscopes. C)have a higher magnification capability because they use natural light. D)have a greater resolution available because they use white light. 2. To study the details of protein molecules on the surface of a cell, a biologist would likely use a A) compound light microscope. B) dissecting microscope. C) scanning electron microscope. D) transmission electron microscope. 3. What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 40x and an ocular lens power of 10x? (2 points) 40x 50x 400x 500x

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.
