When charged particles from the sun strike atoms in Earth's atmosphere, they causeelectrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights
It's not alive, nor is it even an organic compound.
- It cannot respond to stimuli (Responsiveness)
- It cannot secrete hormones (Secretion)
- It cannot send messages along a nervous system or anything similar (Conductivity)
- It cannot break down compounds to usable energy forms (Digestion)
- It cannot absorb broken down compounds as an energy source (Absorption)
- It cannot reproduce (Reproduction)
- It cannot grow--it has no cells (Growth)
- It cannot exchange gases between cells (Respiration)
- It cannot rid itself of waste material (Excretion)
Replication Fork! Is the answer! Hope this helps!
