I can explain e=mc^2 :P
This is the formula that calculates the amount of energy used.
E= Energy
M= Mass
C= Speed of light (a Constant)
Half-life is the time required for an unstable atom to decay half of its total amount of matter.
For fossils to be formed:
Dead
Close to water so scavengers...
survival of the fittest, aka natural selection theory, is that organisms which have hereditary (passed from generation to generation) characteristics which are favourable in the environment are more likely to survive and reproduce.
How old is the earth?

XShiv:
the equation is:
n2 + o2 > 2no
so therefore the answer is d
