Explanation: Transmission of the virus through the biting of infected animals, birds, and insects to humans is known as Zoonoses. Examples: Rabies virus. Alphavirus, Flavivirus, Ebola virus, etc.
3. Ans. D
Explanation: There are four different types of viruses based on the type of host namely Animal viruses, Plant viruses, Bacteriophage and Insect virus.
4. Ans. D
Explanation: Viral diseases are diseases that are caused due to virus namely AIDS, Ebola, Influenza, SARS (Severe Acute Respiratory Syndrome), Chikungunya, Small Pox, etc.
