Are viri alive

Viruses are not considered alive by most biologists because they lack the characteristics that define living organisms, such as cellular structure and the ability to reproduce independently. They can only replicate inside a host cell, hijacking the host's machinery to produce more viruses. Additionally, viruses do not carry out metabolic processes on their own. However, they do exhibit some characteristics of life when they infect a host, leading to ongoing debates about their status as living entities.
