These characteristics are examples of emergent properties.
Well, both subatomic particles of protons and neutrons contribute to the mass of the atom, and thus I believe that the correct response would be D. Protons and neutrons are located in the nucleus of the atom and both are responsible for the mass, atomic mass of the atom.
This phenomenon represents homeostasis. It is a self regulating process used by biological systems to maintain stability while adjusting to conditions that are optimal for survival. If it is successful, life will continue.
In this example the African elephants flap their large ears in the air to help cool the blood that flows through them.
(hope this helps ✌)
Oxidation occurs at the anode.
For both electrochemical cells, this occurs where the cathode and anode is where half reaction occurs.
Hope this helps!
