Question 2.

How have technological interventions facilitated the creation of new knowledge in understanding the world beyond the naked eye? Class 9

Answer:

The invention of microscopes has made it possible to observe structures that are too small to be seen with the naked eye. Light microscopes allow us to see cells, while electron microscopes reveal finer details like organelles. These technologies have helped scientists understand cell structure, functions, and microorganisms.
