Answer: The correct answer is- is not a true living cell.
A virus is an acellular, non living, microscopic, infective agent. It contains genetic material ( DNA or RNA) that is surrounded by a coat of protein. It can not produce energy by its own and requires a host organism for replicating its genetic material ( DNA or RNA).
Example- Bacteriophage ( a virus that infects bacteria for its replication).
Therefore, it is not considered as a true living cell.
Greenhouse gases are REALLY bad for the environment and one of the major cause of global warming. Greehouse gases can stay lasting in the air for 20 to 200 years.
