Because of their high rate of mutation. They also can be hard to track because they infuse their DNA into your body cell DNA and can lay dormant and undetected for years.

Technically viruses are not living as they do not contain any of the membrane bound organelles (mitochondrion) as well as ribosomes, which are present in cellular life forms; viruses contain nucleic acid (either DNA or RNA). All antibiotics invariably act by interfering with the prokaryotic 70S ribosomes during protein synthesis; but antibiotic has no effect on the eukayotic 80S ribosomes. So during viral infection, when person’s general immunity is low they are prone to infection by prokaryotic organisms (eg Staphylococcus aureus); a course of treatment with antibiotics kills the infecting bacterium, unless it happens to be resistant to that antibiotics – eg Methicillin-resistant Staphylococcus aureus, (MRSA) a common hospital bug.

The main reproductive parts are the stamen and pistil.

The stamen is the male part and it is made up of the anthers which produces pollen and the filament that holds the anthers in position.

The pistil on the other hand is the female reproductive part composed of ovary stigma and style.
