Answer: Infection occurs when the host is exposed to pathogens. virus uses the cell's metabolism, and replicates itself while destroying the cell or changing the cell's genetic makeup.
Explanation:
- A virus is a miniscule pocket of protein that contains genetic material.
- Viruses pose a considerable challenge to the body’s immune system because they hide inside cells.
- This makes it difficult for antibodies to reach them. Some special immune system cells, called T-lymphocytes, can recognise and kill cells containing viruses, since the surface of infected cells is changed when the virus begins to multiply.
- Many viruses, when released from infected cells, will be effectively knocked out by antibodies that have been produced in response to infection or previous immunisation.
- Antibiotics are useless against viral infections. So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.
Hence virus are the pathogen that use the cell's metabolism. And replicate itself while destroying the cell or changing the cell's genetic makeup. viruses are so simple that they use their host cells to perform their activities for them

If the tyre blows out then stop
The correct answer for this question would be option D. The characteristic that is not considered as seen in the zones of a deciduous forest would be ground zero. There is definitely a ground zone in the deciduous forest, but it consists of mostly true mosses, club mosses and lichens. The soil of these forests are very fertile in nature. Hope this answer helps.
Answer:
The preferable option will be - D.
D. CNS and PNS
Explanation:
Multiple Sclerosis is a demyelinating disease affecting axons in the <u>CNS </u>nervous system, in contrast to Guillain Barre Syndrome, which strips the myelin sheath from axons in the <u>PNS</u> nervous system.
- Multiple sclerosis is an inflammatory disease in which our own immune system attacks our own nerve tissues and damages the central nervous system (brain and spinal cord).
- Guillain-Barre syndrome is an autoimmune disease in which our peripheral nervous system (PNS) gets affected.
