Answer: D. helps in digestion
Explanation: Gastric juice in the stomach contains HCL which creates an acidic condition(pH1.5-2.0) which is optimal for the action of enzymes in the stomach. HCL stops the activity of salivary amylase & helps to kill bacteria in food. It doesn’t help in digestion cuz it is not an enzyme.
Answer:
The correct answer is C the extraction of high energy electrons remaining from glycolysis and citric acid cycle .
Explanation:
Electron transport chain(ETC) occur in mitocondria and is the last process of aerobic respiration.ETC deals with the transfer of electron from the reducing equivalent such as NADH,FADH2 thereby oxidising them to their oxidized form NAD+,FAD.
The liberated electron from these equivalents utilizes the proton motive force come from the transport of H+ ion cytosol to mitocondrial matrix and then result in the phosphorylation of ADP to form ATP along with H2O by the reduction O2.
Geographical isolation (vicariance) is the main reason for the evolution of either side mouse into new species.
What is geographical isolation?
Two populations of the same species are geographically separated by a barrier, they will eventually become genetically distinct from one another. Even when they are exposed to the same kinds of environmental selection forces and are living in the same region, two populations of the same species can yet become genetically distinct from one another.
A new river cuts through a land mass, separating populations of mice on either side. these mice then evolve into new species on the two sides of the land mass, the separation of a group of organisms by a geographic barrier, resulting in the differentiation of the original group into new varieties or species.
Hence, vicariance is a kind of evolution caused by geographical isolation.

It’s A- nucleic acids arranged in a double helix. Hope this helps!
The atomic number is the number of protons and the mass number is the number of protons+neutrons in the nucleus so number of neutrons = 155-55 = 100
