What are the two reasons scientists say viruses aren't living organisms?

1. They can't carry out the 7 life processes and need to hijack another organism to do so. 2. They can survive in for years in extreme conditions like an airtight container and still infect people.

What are the two reasons some scientists say viruses are living organisms?
