Not true. For all diseases caused by pathogens (even viruses), there is a minimum infectious dose needed to cause disease.
It does vary between different pathogens & between the condition of the host (immunocompromised vs. healthy), but if the minimum infectious dose is not met- then the body is typically able to snuff out the intruders before they can do any real damage.
Hope that helps!

Answer:
354 cm³
Explanation:
<u>Step 1: </u> calculate the density of PEG 400
= 1.13X1 = 1.13
<u>Step 2:</u>
Molecular weight of PEG 400 = 400g/mol
<u>Step 3:</u> calculate the volume of PEG 400 to be measured
= 353.98 cm³
≅354 cm³
Work = (force)x(distance)
Since we're lifting, the 'force' is the weight of the apple.
Weight = (mass)x(gravity)
Weight = (0.180 kg)x(9.8 m/s^2)
Weight = 1.764 Newtons
2.0 J = (1.764 N) x (distance)
Distance = 2.0J / 1.764N
Distance = 1.13 meters
