Allopatric speciation occur due to various environmental factors with in the environment.
Explanation:
Speciation occur when two population become so genetically different and the can not interbred to produce fertile off spring. The allopatric speciation occur when population become sepret and diverge over time due to natural selection,genetic drift,and mutation.Genetic drift is the sudden loss of gene from a population which cause the population evolvation. Mutation is also change in the genetic makeup of an individual.Natural selection is the phenomena selected by nature and natural forces are involve to select the trait in a living organism.
Answer:
The statement is true
Explanation:
Asepsis means the absence of infection-causing germs and surgical asepsis means the absence of all the microorganisms or spores in any invasive process.
