The DNA virus uses nucleus of the host to replicate it genetic material since it lack reverse transcriptase enzyme.The similarities between the DNA virus with human protein it make difficult to treat this virus without damaging the host cell.
while
RNA virus has reverse transcriptase enzyme which is used to replicate its genetic material, but it lack ability to check errors, which led to higher mutation rate.The transcriptase enzyme is used to make vaccine which is used to treat RNA virus
I don't know which specific examples do you need to include, but I am pretty sure that as a regular animal, squirell might need such resources as <span>food, water, and a habitat. These three points are enough to satisfy basic needs.</span>
Answer: Too many deer in a given area results in overgrazing and the eventual loss of brush and shrubs in forested areas. Loss of undergrowth means no place for small animals and birds to shelter and nest. The result is the disappearance of many native species that no longer have access to the habitat they need.
Answer:
Both conditions are caused by an inability of the body to produce adequate acetylcholine.
Explanation:
Botulism is a potentially fatal condition caused by the toxin of bacteria <em>Clostridium botulinum</em>. Early symptoms are weakness, slurred speech, blurred vision etc. It may lead to vomiting, abdominal swelling and respiratory failure if not treated. The toxin hinders the release of neurotransmitter acetylcholine due to which motor neurons are not able to send signals to muscle cells. Muscles are not able to function properly due to which paralysis occurs.
Myasthenia gravis is also a neuromuscular condition like botulism. But unlike botulism release of acetylcholine is not hindered here. The receptors for acetylcholine are destroyed or altered by body's own immune system. Acetylcholine despite being present is not able to relay the signal which leads to muscle weakness. Symptoms are almost similar to those of botulism.
