Answer:
There is a great difference between light and scanning electron microscope. The source of illumination is light rays in light microscope while in scanning electron microscope electrons are the source of illumination.
The resolving and magnification power of scanning electron microscope is much greater than that of a light microscope. The magnifying power of a light microscope is 1000X and of electron microscope is 10,00,000X.
In light microscope image is seen through the eyepiece while in scanning electron microscope it is seen on a fluorescent screen. Even small specimens up to 0.1 micrometers can be seen by scanning electron microscope which is not possible to see by light microscope.
Differential reproduction means that some organisms in a population produce more offspring than others.

Differential reproduction refers to the difference between individuals in a population and how many offspring they are able to leave.The best adapted organisms to a given environment will leave more offspring than those who are not well adapted. Differential reproduction depends on the natural selection.</span>
6-C (breaks off)
7-C(they secrete acid that breaks away rocks)
Answer:
A liter is a cubic decimeter, which is the volume of a cube 10 centimeters × 10 centimeters × 10 centimeters (1 L ≡ 1 dm3 ≡ 1000 cm3).
Explanation:
Hence 1 L ≡ 0.001 m3 ≡ 1000 cm3, and 1 m3 (i.e. a cubic meter, which is the SI unit for volume) is exactly 1000 L.
