Answer:
Natural selection produces changes most quickly in species with short reproductive cycles.
Explanation:
Natural selection implies a process of changes in the genome of species, induced by their environmental conditions, which allow them to survive. The processes of natural selection usually manifest themselves after long periods of time and are synonymous with adaptive evolution.
Since natural selection depends on the changes observable in successive generations within a species,<u> in organisms with short reproductive cycles the changes promoted by natural selection could be observed most quickly</u>.

Answer:
A. a protein
Explanation:
Proteins function as enzymes in most of the catalyzing reactions, that increases the rate of reaction within cell.
Proteins are consist of multiple numbers of amino acids and the twisting and folding amino acids provide a unique identity to enzymes. Not all the proteins are enzymes but all the enzymes are proteins.
For example: Trypsin, Pepsin, and Lipases.
Hence, the correct option is "A. a protein".
Anaerobic respiration is the process by which some organisms produce energy in the absence of oxygen. Instead of oxygen, organic and inorganic molecules are used as electron acceptors. One example of anaerobic respiration is fermentation.
In latic acid fermentation, one molecule of glucose undergoes glycolysis to produce two molecules of pyruvate. The two molecules of pyruvate then undergo fermentation to produce two molecules of lactate. The lactate will be transported to the liver. The lactate can be reconverted to pyruvate and utilized for energy. Latic acid fermentation occurs in the muscles.
