Small drops of oil formed by a sprayer are allowed to fall in between a positively charged upper metal plate and a negatively charged lower metal plate. The space between the two plates is irradiated with X-rays. This displaces some electrons of the air molecules, which consequently get ..
The Fundamental Unit of Life - Test Questions
Question 1 - Question: Why were the scientists not able to observe most of the cell organelles before 1940? Answer: Before 1940, scientists could view the cell only under a light microscope. The invention of the electron microscope in 1940 enabled the scienti..
