Answer:

Theory of spontaneous generation.

Explanation:

Theory of spontaneous generation stated, life arose from non-living things. Pasteur disprove this theory by S-shaped tube experiment. He used swan-neck flasks (twisted necks) and filled them with sterilized beef broth. This allowed entry of air to the flasks from outside, but not microorganisms.

In these sterilized flasks, microorganisms did not grow as there was no entry of airborne microbes. But if the necks were broken, microorganisms entered and allowed growth of microorganisms.

Thus, Pasteur proved life comes from pre-existing life and disproved theory of spontaneous generation.

Answer:

↓

Explanation:

I can't really read what you have typed, but the subscripts are the little numbers such as this 2 in H₂O. So using the blue pen, I'm assuming you would circle the little numbers. The coefficients are the numbers in front of the elements so from what I can read, in 2HCl the 2 would be circled in the orange. So in a simple way the subscripts are the tiny numbers that are at the bottom (usually after elements), and the coefficients are normal numbers in front of the whole element.

Hopefully that makes sense! :)
