What must viruses rely on for replication?
they must find a host cell in the infected body and take it over to force it to replicate
Do viruses move independently or dependently?
Some viruses can move parts of their body, but most viruses rely on their hosts.
What are properties of viruses?
viruses are non cellular , they have no sexual or asexual reproduction they reproduce by replication
Why are viruses considering to be non living?
Many scientists consider viruses to be non living because each and every living organism must carry out these 7 life processes for it to be considered living: Movement, Reproduction, Sensitivity, Growth, Respiration, Excretion and Nutrition. Viruses do all of these things except reproduction, which they cannot do. Instead, they multiply by using other living organism's cells which has caused a lot of debate over whether that counts as reproduction in the scientific community.
What do viruses have to rely on for replication?
They rely on their host. They can not reproduce on their own, so they are not considered living. They inject genetic information into a host cell and make the cell produce more viruses.
What are reasons viruses are considered non living?
Two very important reasons are growth and reproduction. Viruses do not have a way of converting potential energy, or photonic energy, into useful forms; no metabolism. Viruses can not reproduce on their own and must hijack a cell's reproductive machinery to reproduce themselves.

Are viruses mobile or immobile?
Viruses are immobile. They can not move on their own, and rely on their hosts biological systems to move them around.
Why are viruses considered?
they are able to multiply, which could be seen as a form of reproduction
Do viruses have a carbohydrate store?
No. Virus need to rely on hosts to reproduce.
Viruses are not classified as life because they carry out no life processes except?
reproduction
How do viruses reproduce compared to bacteria?
Viruses replicate inside body cells, using the host cell to do the work and provide the materials for reproduction. Bacteria reproduce outside body cells and, since, unlike viruses, they are living organisms, bacteria are able to do the work and production of new bacteria without a need for a host.A description of the 'Lytic Cycle', the process that some types of viruses follow in reproduction, is given in the related questions below for more detail of the process of reproduction of some viruses inside body cells.
