... 70% are localised within coated pits: work out how many coated pits there are. Ive got: 3,400 * 2% = 68 micrometers(squared) every pit has a 100 nanometer diameter. area of a circle 2*pi*r(squared) 100nanometers=0.1micrometer r=radius 2r=d r=0.05micrometers 2*pi*0.05(squared)=0.0157micromters(squared) ...

Viruses are tiny geometric structures that can only reproduce inside a living cell. They range in size from 20 to 250 nanometers (one nanometer is one billionth of a meter). Outside of a living cell, a virus is dormant, but once inside, it takes over the resources of the host cell ...

... problem here seems to be the use of "environment" as a global parameter, but changes in a molecule's environment can be just changes in nanometer-sized areas. Any variation in a thousand different environmental factors over tiny distances (or not-so-tiny distances) could affect the viability ...
