These jars show the set-up from francesco redi's experiment with meat and maggots. after a few days of sitting out, the covered jar did not have any maggots in it. what is the most likely explanation for this?

Francesco Redi's experiment was the first experiment that disproved the theory of sponatenous generation. He explained that life cannot originate from the inorganic or non living matter.

He placed the two maggots in two different jars. The one jar is uncovered and contains meats in which maggots appear. The another jar is covered and no maggots appear on meat. This explains that maggots flies eggs are not formed in the covered jar as eggs are not available for the life. Maggots do not originate from the meat.Life originate from the pre existing life.

Explanation:

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
