Reducing agent<span> is an element or compound that loses an </span>electron<span> to another </span>chemical species<span> in a </span>redox <span>chemical reaction and they have been oxidized.

Parasitism... basically a tick and a dog. The dog is the host, which is harmed by the tick.
Density = mass / volume
Mass = 5 kg
Volume = 50 cm³
d = 5 / 50
d = 0,1 kg/cm³
