Explanation / Answer

1. Spontaneous generation theory.

Pasteur with his swan neck flask experiment proved that organisms do not appear from nowhere. they are generated from their parents. he disproved spontaneous generation theory.

2.more likely to produce offspring

3.causes the population to diverge into two groups

Diversifying or disruptive selection increases genetic variance when natural selection selects for two or more extreme phenotypes that each have specific advantages.
4.All of the above

5.DNA sequences

6.Producers

7.Mutualism
