Answer 1

Answer:

1. Ability to tell two points apart    - c) Resolving power

2. Magnifies an object using light and lenses  - b) Optical microscope

3. Magnifies using streams of electrons  - e) Electron microscope

4. Single body tube      -         g) Monocular      

5. Lens found in the eyepiece  - d) Ocular lens  

6. Two eyepieces   - f) Binocular

7. Magnifying lens closest to the specimen- a) Objective lens

Explanation:

Resolving is defines as ability of the optical instrument to form two separate images of closely placed objects. Hence( 1 )matches with (c)

Optical Microscope is an instrument that uses the lenses and light to view an enlarged image of small objects/species Hence, (2) matches with (b)

In electron microscope, beam of electron is used instead of light and hence (3) matches with (e)

It is just like half of binoculars. Since binoculars have two tubes, monocular have one tube only. Hence (4) matches with (g)

Ocular lenses are also known as eyepiece thus, (5) ,matches with (d)

Objective  lenses are placed close to the specimen being observes or it is placed close to the object hence (7) matches with (a)
