Question

how were redis and pasteurs experiments different?
○ redi studied broth, but pasteur tested meat.
○ pasteur studied flies, but redi tested meat.
○ pasteur tested for microorganisms, but redi studied larger organisms.
○ redi tested for microorganisms, but pasteur studied larger organisms.

Explanation:

To solve this, we analyze each option:

• Option 1: Redi studied meat (for maggots), Pasteur studied broth (for microorganisms) – this is reversed, so incorrect.
• Option 2: Pasteur studied microorganisms in broth, Redi studied flies/maggots on meat – this is reversed, incorrect.
• Option 3: Pasteur's experiment with broth tested for microorganisms (like bacteria), Redi's experiment with meat studied larger organisms (flies/maggots) – this matches their experimental focuses.
• Option 4: This is the opposite of the correct relationship – Redi studied larger organisms, Pasteur studied microorganisms.

Answer:

C. Pasteur tested for microorganisms, but Redi studied larger organisms.
