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.

Answer: Chlorine-36 (^36Cl) is an isotope of chlorine.
Explanation: Chlorine has two stable isotopes and one naturally occurring radioactive isotope, the cosmogenic isotope ^36Cl.
The lack of centrioles in nerve cells prevents them from undergoing mitosis and meiosis, which prevents them from dividing. Nerve cells do not divide throughout their lives and do not lengthen without doing so.

What is nerve cells?</h3>
The central nervous system is constantly receiving information about the external and internal environment (in the form of sequences of action potentials) from nerve cells, also known as neurons.
Nerve cells are “excitable” cells that may convert a range of stimuli into electrical impulses (CNS). Despite the complexity of the nervous system, neurons and glial cells are the only two types of nerve cells that make up nervous tissue.
The structural and operational components of the nervous system are called neurons. Nerve impulses are electrical signals that are transmitted by them. Neuronal support is provided by glial cells.
Therefore, nerve cells do not reproduce and, if damaged by injury or disease, are lost forever.
