Microscopes play crucial roles in scientific exploration, antibiotics target specific bacterial components, and not all microbes are harmful, some are necessary for various important processes.

Explanation:

Use of Microscopes in Science:

Light Microscope: Ideal for viewing general cell structures due to its lower magnification. Scanning Electron Microscope: Ideal for detailed surface imaging due to its high resolution. Transmission Electron Microscope: Ideal for detailed internal structures due to its high magnification.

Advantages and Disadvantages:

Light Microscope:
- Advantages: Low cost, easy to use.
- Disadvantages: Limited resolution and magnification.
Other Microscopes:
- Advantages: High resolution and magnification.
- Disadvantages: Expensive, complex operation.

Cell Theory and Formation: The formation of an adult human follows the concept that all living organisms consist of cells.

Target of Antibiotics in Bacterial Cells: Antibiotics target components like bacterial cell walls or protein synthesis mechanisms unique to prokaryotic cells.

Reasons for Not All Microbes Being Harmful: Many microbes are beneficial in processes like digestion, decomposition, and nitrogen fixation.

Ribosomes in Cells: Aside from red blood cells, ribosomes are abundant in cells actively involved in protein synthesis like pancreatic cells.
