I would say to not eat any processed meat.
It’s called diffusion, it’s the random motion of particles from high areas to low areas.
1) they have similar chemical properties.
for example fluorine from the 17th column is a non metal so does all the elements of that group.
2)they have same valence electrons in their outermost shell
example
electronic configuration of
hydrogen 1, lithium 2,1, sodium 2,8,1 and so on.
3) have same valency.
Multicellular? or do you mean animals?
