They transport the pathogens by biting, or a human eats an infected animal.
Cells are so small so the surface area and volume of them can be proportional to each other. This helps with the efficiency of the cell's absorption and waste expulsion processes. Also by the cell's smallness, communication from the nucleus to other organelles is fast and the cell can be regulated while the conditions for diffusion are still ideal.
Speed = frequency x wavelength
100 x 0.2 = 20
I actually dont have the time right now but if you look up definition of (word) the definition will come up. Just put it into a shorter version!
