Yes.
No, it means that it has the potential to be alive. I think that for something to be considered alive, then it must be able to move, reproduce, sense, grow, reproduce, excrete and rely on nutrients for its survival. (note: that's just my opinion)
Yes, an organism by definition is not only alive, it reacts to stimuli, maintains homeostasis, grows and can reproduce. Once it dies, it returns to the soil or water as organic matter. If something cannot be alive, it is inorganic. This includes all the minerals on the earth or what we sees as "rocks".
Unicellular organisms are alive. They are considered living entities because they exhibit the essential characteristics of life, such as the ability to reproduce, respond to stimuli, and metabolize nutrients for energy.
Something is alive if it can reproduce, respond to changes in his/her/its surroundings, can convert some form of energy into energy to sustain his/her/its self, and has DNA. Thus, a virus is not alive because it can not reproduce on its own-it needs a host. A baby human is alive for the above four reasons (though reproduction is a capacity that will develop with maturity).
Bacteria are alive as: 1-they have tails and they move about here and there. 2-They have an ability to reproduce them selves. 3-They multiply very fast______ a single bacterium breaks itself into two every half hour.

Something is alive if it can reproduce, respond to changes in its environment, can convert some form of energy into energy to sustain its self, and produces waste.
Viruses are not considered alive because they lack the ability to reproduce unless they have a host to reproduce for them. When viruses are not attache to a living cell they lose all living characteristics.
They have to reproduce, respond, react...like a sunflower- it reproduce (more sunflowers) it respond (It turned to where the sun is! sunflower) react=respondPeople- reproduce (*throws up*) respond (when something is too hot, you move your hand away from it, you won't let it burn)
No. Tornadoes do not reproduce. They are not alive.
Biological organisms are considered alive if they exhibit certain characteristics, including the ability to grow, reproduce, respond to stimuli, maintain homeostasis, and undergo metabolic processes. These attributes help differentiate living things from non-living entities.
They reproduce by mating.
Erm...no. Maybe in the future stuffed animals will be imbued with artificial intelligence that will be considered 'alive', but for now however they are not.
1 obvious way is if it can move. others would be like: can it produce heat/cold, if it is alive/dead, if it can reproduce, if it can take in energy from the sun or other things, it you can see it, etc.
No, quarks are elementary particles that make up protons and neutrons. They are not considered alive because they do not have the characteristics of living organisms, such as metabolism or the ability to reproduce.
Viruses are prokaryotes and not Eukaryotes. Therefore they are not alive. Since it is not considered to be alive they do not belong in the 5 kingdom classification; Monera, Fungi, Plantae, Animalia, Protista. Bacteria are living once celled organisms and belong to either bacteria or Archaea. *Viruses not considered alive because they need a host to be able to reproduce. They cannot reproduce on their own.
