Cells came from nonliving things.

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.

What are the two theories that are combined in the synthetic theory of evolution?
Alika [10]

The Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.

<h3>Synthetic theory of Evolution </h3>

  • The synthetic theory of evolution states that evolution are the changes occurring in the allele frequencies within the populations.

The theory explains that changes in the genes of organism are what causes the evolution of organism.

The Darwinian theory of Evolution states that organisms better adapted to their environment survive and give birth to offspring suited for their environment.

The Mendelian theory of genetics states that the combination and resassortment of genes are responsiblefor character inheritance.

Therefore, the Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.
