yes it is
Viruses
They arent alive
The cell theory applies to all living cells, including those found in plants, animals, fungi, and single-celled organisms. It states that all living organisms are composed of one or more cells, cells are the basic unit of structure and function in living organisms, and all cells come from pre-existing cells.
An exception to the cell theory is the existence of viruses, which are not composed of cells and cannot perform metabolic processes independently. Viruses rely on host cells for replication and do not have the cellular structure that characterizes living organisms. This challenges the cell theory's assertion that all living organisms are made of cells.
Nonliving things are not made of cells.
Viruses
Viruses are not considered part of the cell theory because they are acellular entities that require a host cell to replicate.
The cell theory applies to all organisms.
The first cell did not come from a preexisting cell and viruses
They arent alive
only in a host cell
How can we apply the cell theory to better understand living and non living things

No. Cell theory is the idea that all living things are made of cells. Glaciers are not alive and do not have cells, so cell theory does not apply in any way whatsoever.
Not to virus because they are not life forms!
They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
