Answer:
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.

Answer:
Ribose
Explanation:
DNA is a large molecule, a type of nucleic acid which store and act as a genetic material of the cell. DNA molecule is formed by the repeating monomer units called nucleotides.
Each nucleotide is made up of three subunits as:
1. 5-C sugar: De-oxyribose formed by the removal of oxygen group from 2' OH group of ribose. Ribose is the sugar molecule present in RNA nucleic acid.
2. Phosphate group (PO₄³⁻)
3. Nitrogenous bases: adenine, guanine, adenine and cytosine.
Thus, ribose is the correct answer.
