In the flask experiment (Pasteur's experiment) showing that living organisms arise from other living organisms, which one of the following statements MOST accurately describes hypothesis? Group of answer choices

1. Microbes should be capable of growing equally well in sterile broth contained in both straight-neck and swan-neck flasks.

2. The first cells must have come from chemical reactions occurring in early Earth.

3. Sterilization of broth kills microbes.

4. Straight-neck flasks allow for more contamination than swan-neck flasks.

5. If microbes arise from nonliving matter, they should appear spontaneously in sterile broth.

The statement that most accurately describes the hypothesis is Statement 5 - If microbes arise from nonliving matter, they should appear spontaneously in sterile broth.

Explanation:

The statement is most accurate because he exposed two broth culture dust particles, one in a broken flask left opened while the other in an enclosed unbroken flask. So the one left open in a broken flask indicated microbial growth while the other was clear, simply showing that microorganisms do not occur from non-living materials alone.
