Very good question. Viruses are not considered alive by many (I might even go as far as to say most scientists wouldn't consider viruses alive, but I'd have to ask more of them first to be sure). Neither is a rock! Those that think viruses are alive are, as you have said, suggesting pretty much anything in the world can be considered alive. If a virus is alive, then by folding a piece of paper into a paper aeroplane I have created life. A paper plane alive? Absurd!
Ridiculous really isn't it?
Viruses aren't alive. They're just molecules that happen to react in a certain way to seem alive to anyone that hasn't studied a biological natural science for several years. But once you understand what happens on atomic and molecular scales, you realise they're not alive at all. No different from a molecule of glucose. It goes is, something is done to it, and it comes out.
The only reason a Virus would be considered alive is because they are structured in such a way as to allow them to be reproduced, and contain proteins with the ability to influence the chemical machinery of cells in other living things.
What else can I help you with?
Why is a virus considered alive while a rock is not?
Well a rock isn't really alive, and a virus is actually moving if you get a scope to look at it. it gets into your body to form a disease. We know you cant really see it but try to wash you hands free of germs and viruses! ;)
Is considered a biotic factor?
no a rock is not alive
Explain why a virus is considered alive while a rock is not?
Mainly because rocks don't reproduce. A lot of scientists don't consider viruses alive, either, for pretty much the same reason: they can't reproduce themselves, they have to co-opt the machinery of a living cell in order to do so.
Neither a rock nor a virus can make food or change food into energy explain why a virus is considered alive while a rock is not?
Viruses are considered alive because they can replicate and evolve, although they require a host cell to do so. Rocks, on the other hand, do not have the ability to carry out any life processes or replicate themselves. The defining characteristics of life, such as growth, reproduction, and response to stimuli, are not observed in rocks.
Which of these objects is are alive A protein molecule A cell A virus?
A cell is considered alive because it can independently carry out the functions necessary for life, such as metabolism and reproduction. A protein molecule is not considered alive as it lacks the ability to perform these functions on its own. A virus is a debated topic in science as it cannot reproduce on its own but requires a host cell to do so, blurring the line between living and non-living.
Crystals such as rock candy grow larger as they are forming are these crystals alive?
No, crystals are chemical compounds that are not considered to be alive.
Which kingdom does virus belong to?
Viruses dont fall under the 6 kingdoms because they are not considered to be alive... :D
What keeps a virus alive?
The Virus is a Harmful code which spreads all over the Computer and take all the memory location and spoils it.If you are Pc is infected with virus then immediately scan it with Anti-Virus software's.
Is HIV alive or dead?
It's a virus. It's alive.
Why isnt a virus alive?
A virus does not fulfill all requirements for life, eg. no reproduction through meiosis or mitosis
What does it mean that a microorganism is non-pathogenic?
A pathogen = a virus. An organism, macro or micro, is alive, but viruses cannot technically be considered 'living.' Thus, non-pathogenic means 'not a virus'.
Is virus an autotroph or hetrotroph?
Neither. A virus is not really alive in a traditional sense.
