Question

How are virus infections like a “sneak attack”?

Answer 1

Virus infections are like a 'sneak attack' because the virus tricks host cells into allowing it to enter and reproduces while evading the immune system's response. HIV is an example of a virus that changes rapidly, making it hard for antibodies to recognize and combat the virus.

Step-by-step explanation:

In virus infections, the virus enters host cells by exploiting specific binding sites on the cell's surface. The virus coats mimic the cell's molecules, tricking the cell into allowing the virus to enter. The virus then interacts with the immune system, prompting the production of antibodies to fight the virus. However, some viruses, like HIV, rapidly change their surface markers, making it difficult for antibodies to recognize and destroy the virus.

Answer 2

Viruses enter human body like an invader and uses the living cells to replicate causing infections in the cell or can damage it.

Step-by-step explanation:

The attacks of viruses on the body of living organisms is compared with a ‘sneak attack’ as they invade the body and enters into a living cell to replicate themselves. This may cause damage or bring about changes in the cell causing sickness and infections.

They can hide themselves on our body attacking sneakily to harm the immune system to fight the infection. This stealth infection can result in fever, damaging immunity, disorder etc.
