The characteristics have been determined to seven different actions, (movement, respiration, sensitivity, growth, reproduction, excretion and nutrition, known as MRS GREN)
Viruses have been found to complete no independent metabolic activity. They can move from cell to cell through actions such as sneezing and coughing if a respiratory virus, or contamination from bile and faeces.
They can also not respire, as they don't carry the required enzymes to do this. All they do is insert their DNA into the host cell for it to be reproduced through mitosis, and make the cell burst so as the dna is in the bloodstream.
In terms of sensetivity, they have no sensetivity, as they have no sensory input.

Life processes MRS GREN to explain the differences between living and non-living things?
MRS GREN is an acronym that stands for movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition. Living things exhibit all of these characteristics, whereas non-living things lack one or more of these processes. These life processes help differentiate living organisms from non-living objects.
Why arent viruses considered living things?
viruses, in the first place, are non living. when they enter a substrate (e.g. host), that's the time they exhibit actions and processes pertaining to a living organism. this is also the reason why putting viruses in the classification system is still on debate.
What characteristics of life do viruses show?
Several traits could lead one to consider viruses as living organisms. They carry and transmit their own genetic information, they consume resources, they move, or rather they take advantage of a host in order to move, and they initiate self-replication when in a suitable host.
What is a difference between bacteria and viruses shows that bacteria are living organisms and viruses are nit?
Part of the definition of a living thing is that it can reproduce itself, which a virus can't do. Bacteria reproduce like any other cellular organism: by cellular division. Viruses, however, can not reproduce themselves. Instead, they infect other cells and force those to make more viruses.
How are viruses similar to living organisms?
There is a lot of debate about this one. Viruses are dimply DNA in a protein capsule. They have none of the cellular machinery that sustains life, but instead use the resources of the host cell. Some consider viruses to be a form of life. Others do not.
What one of the 7 life processes can viruses do?
VIruses can only reproduce. They can not respire, excrete, nutrition, grow, they don't have sensetivity either. Remember: viruses still are living things because they have genes in them.:) hope it helped. thanks! :P

Are viruses identified as livivg things yes or no?
viruses are not living things because they only carry out reproduction which is only one of the characteristics of a living thing. a thing to be called living it should have all the seven characteristics listed below: Respiration - viruses don't respire(breathe) Nutrition - viruses do not feed Excretion - since they don't eat and breathe they don't give out anything Sensitivity - they are not aware of the surrounding expect for their survival Growth - viruses don't grow no increase or decreaase in size Movement - they move Reproduction- they reproduce since only two characteristics are present viruses are declared non living .
What is one of the exceptions to a characteristics of life?
One exception to the characteristic of life is viruses. Viruses are considered non-living because they cannot carry out the basic functions of life on their own and require a host cell to replicate.
What is one property of life that viruses share with living things?
they both have at least one cell.
What is one reason that viruses are considered nonliving?
Viruses lack the ability to carry out metabolic processes on their own, such as growth and reproduction, which are characteristics of living organisms. They also do not have cellular structure like living organisms do.
Will a couple glasses of wine show up 20 hours later?
Only one day? Definitely You have no idea the sensitivity of today's chemical processes.
Why is there is debate about the viruses being alive or dead?
The debate is not about whether viruses are alive or dead. Rather, there is debate about whether a virus should be considered a living thing. Viruses are not like living cells, because they do not have metabolic processes, and they cannot reproduce themselves. Instead, they invade a host cell, and the virus's genes cause the host cell to produce new viruses. However, the question of whether this "counts" as being alive is a semantic one. Viruses have some properties of living things, and they lack other properties, so the question of whether they are "alive" comes down to one's definition of the word "life."
What is one reason that viruses are considered to be nonliving is theyare not made of protein?
Viruses are considered nonliving because they lack cellular structure and do not possess the machinery necessary for metabolism or reproduction on their own. While they do contain proteins, they cannot replicate or carry out metabolic processes without invading a host cell. This dependency on a host for reproduction and their inability to sustain life independently are key reasons why viruses are classified as nonliving entities.

What one of the seven life processes can a virus not do?
they cant conduct reprodution
How does the mitochondria function?
It uses one of the seven life processes, Respiration.
