There are number of endemic species, because island isolation promotes allopatric speciation and the latter occurs when species become separated from each other to the level that prevents genetic recombination.

<span>the virus injects the genetic info. this can be RNA or DNA. retroviruses inject RNA. after injection, the host cell transcription/translation machinery is hijacked and starts making virus proteins from the viral genes.</span>
Answer:
By action potential nerve contract the muscle
Explanation:
The muscle contract when the nervous system sends action potential to the muscle. So the nervous system delivers signal to muscle, the first signal reaches the neuromuscular junction. The signals are passed by a chemical messenger called neurotransmitter release by motor neurons, the chemicals bring reaction and shorten the muscle fibre. When neurotransmitter are absent or reduce in concentration the process reverse and muscle relax again.
