Viruses are not alive. Although they sort of “hack” a host’s cells and reproduce, they do not breathe or move on their own. A virus will sit on a counter forever if it’s untouched. Viruses are spread by physical contact, not because they can move around on their own.
Although viruses can attack and hack, and use your cells to reproduce, they are programmed to do so.
Cells are very much alive, while viruses are not.
Answer:
Answer - 9 : 37
Explanation:
Allele frequency refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of the gene.
When growing cultures, the agar is<u> inoculated</u> to separate pathogenic colonies of organisms from colonies of normal flora.
Agar is the medium that is used for growing natural, common flora of microorganisms as the majority of the microorganisms can sustain in the agar medium.
If we want to determine a separate pathogenic colony of organisms in an agar medium then we need to inoculate the agar growth medium so that the pathogenic organism is separated from the normal flora of the microorganism. This technique allows us to filter out the cells that have the pathogenic microorganism in it.

plastic items take up to 1000 years to decompose in landfills. But plastic bags we use in our everyday life take 10-20 years to decompose, while plastic bottles take 450 years.
I hope this helps
<span><em>Whether living or non living:</em>
<em>When you put a sample of tissue under a microscope, if u can see a cell membrane, and can identify some cell structures like nucleus, mitochondria, vacuoles etc. , it was living, if not, its a non living thing.</em></span>
<span><em>However some cells don't have a nucleus( eg. prokaryotic cells), but all cells have a cell membrane or some sort of protective covering to contain the cell's insides. </em></span>
<span><em>To check if your specimen maybe-once living, maybe-still living "something", is living, get a look at it through an electron microscope - thats the best microscope ever- and see if the mitochondria's making any ATP( adenosine triphosphate, source of energy for most organisms), if it does, its living. If not, no</em></span><em>n living. :)</em>
