Is a T4 bacteriophage alive?
Short answer? Good question. Long answer? Define alive. Generally, it is accepted that a living thing does seven things: 1. it is organized 2. it grows 3. it reproduces 4. it responds to stimuli 5. it takes in energy and gives off waste 6. It maintains its own internal environment 7. it adapts to its environment. Of those, viruses only do 1 and 3, and even then they only do 3 in the presence of bacteria. My answer is that no, viruses are just very complex chemicals.
Why are lipophilic viruses easier to kill?
Lipophilic viruses require the lipid (fatty) envelope to remain active ("live"*), and the fatty layer can be destroyed by alcohol. Non-lipophilic viruses do not require this fatty envelope, and the protein layer (capsid) is more resistant to alcohol. *Note: viruses are not actually alive, they are only genetic codes with 1 or 2 (lipophilic) protective layers. Biologists call "live" viruses *active* and "dead" viruses *inactive* or *inactivated*.
Why don't most scientist consider viruses to be alive?
Most scientists consider viruses as the link between living an non living organisms. Viruses are considered non-living by some scientists because - 1) They donot perform any metabolic activities. 2) Outside the host cell , viruses are present only in crystalised form. (Even after it is un-crystalised , it does not lose it's capacity for infection) 3) It does not require any sort of "food".
Size range of viruses?
1/100th of bacteria.
What are non living things not made of?
most of them are actually made of metal, cloth, rubber, leather and plastic Under non-living things, there are two groups: 1) Once Alive 2) Never Alive Once alive are things that are from alive things such as the skin of the snake used to make a handbag. The snake skin is a non-living thing but it was classified under once alive. Never alive are things such as some diamonds, minerals that are extracted from the ground. They are not alive, not even from where they are extracted. That is never alive.

What is the smallest group of living things?
The smallest living things depend on how a living thing is defined. Some biologists do not believe viruses are living organisms because there are no free living forms (all are parasitic) and because they must reply on their host for reproduction. Others believe that, despite this, they have an existence of their own separate to the host and are subject to natural selection and are therefore alive. If you accept viruses are not alive, the smallest living things would be amongst the bacteria or protists. Bacteria are single celled organisms with no cell nucleus while protists have a nucleus. Generally the bacteria are slightly smaller but their sizes overlap. If you accept that viruses are alive, the smallest group are the Parvoviruses between 18 and 26 nanometres. These are single stranded DNA viruses. 1 nm = 1/1000000000 metres or 0.000039 inches.
