Endemism
Endemism is the state of a species being native to a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere.
Explanation:
Endemic species are those that are found in just one region and nowhere else in the world. For example, kangaroos are originally endemic to Australia and are found nowhere else in the world. ... The Tasmanian Tiger is one such animal that was endemic to Australia, Tasmania and New Guinea. But now, it is extinct.
Bromide ion(Br-) is an anion(negative ion) that has one more electron than a neutral bromine atom.
The correct answer is : Non-native species is the example that affects biodiversity.
These species can be an agent of unacceptable economic, biological or social aftermath.
However, these species still provides in the regional biodiversity like biotic interactions and species richness and ecosystem services.
Answer: The sodium-potassium pump.Explanation:
The concentration of sodium and potassium inside and outside the muscle cells are important in the regulation of contraction. These concentrations differ when a muscle is relaxing or contracting.
<span><span>Contraction: potassium concentrations are higher outside the cell than inside the cell.</span><span>Relaxation: the potassium concentrations are higher inside the cell than outside the cell.</span></span>
hope this helps :)
