This is commensalism. One benefits and the other is neither hurt nor gaining anything.
Answer:
The sceintific law explains the behavior of natural phenomena.
Explanation:
Allopatric speciation is said to occur when two groups of organisms are separated by a physical or geographical barrier. Examples of such barriers are ocean, mountain range, rivers, etc. A good example of allopatric speciation is Galapagos finch. Different species of this bird can be found in different islands at Galapos, which is located at Pacific Ocean off South America. The ocean is barrier that isolate the species from one another.

Explanation:
22. Robert Hooke was an English scientist, but he did publish his microscopic observations
23. Anthrax is an infectious disease caused by rod-shaped bacteria known as Bacillus anthracis. It is quite common in livestock and can be passed to humans
24. Vaccinations are a direct application of the study of microbes. Microbes are directly used in the production of viruses - a small amonut of the microbes or its proteins can invoke an immune response that the body will remember the next time it is exposed to the pathogen.
25. Telocentric chromosomes have their centromere located at one end of the chromosome. The ends of the chromosome are called telomeres.
26. Louis Pasteur disproved the theory of spontaneous generation with his famous swan-neck flask experiment. He found that microorganisms could not grow in sterile conditions. He then proposed that “life only comes from life.”
27. The germ theory is the idea that pathogens (microorganisms) can cause disease. Before that, the working theory was than diseases spontaneously generated.
28. When chromosomes are duplicated during DNA replication before mitosis, the two identical chromosomes are called sister chromatids
29. A microscope is a tool that allows researchers to see very small structures
30. The cell membrane is composed of a lipid bilayer that surrounds the cell and controls the entry and exist of substances.
Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. The chemical equation is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water).
