Answer: Gene Pool
Explanation:
Gene pool is the collection of all the gene and various allelic form of those gene within a population.
Variation naturally occurs among the gene of members of the same species that interbreed.
Gene pool It is therefore the total number of gene of all the members among the population of a particular species. Gene pool is used to determine the level of mutation, variation, genetic diversity among members of a population.

Answer:
Neurons have stable, relatively unchanging internal environments.
Explanation:
Neurons or nerve cells is the structural and functional unit of the nervous system. Neurons consists of the dendrites, axon, cell body and different cell organelles.
The neurons have mitochondria that meets the high ATP requirement and and consume more oxygen. The network of rough endoplasmic reticulum and ribosomes produce large number of proteins in neuron. The internal environment is never stable and gets changed as the nerve impulse transmission occur through the neuron. The membrane potential of the neuron gets changed and changes its internal environment.
Thus, the correct answer is option (B).
