Astronomy is a branch of science that studies the Earth and
the universe. Since the age of the Earth
will be based on how it starts, or how the universe starts, astronomy surely
has the most proof that Earth is approximately 4.6 billion years old.
Answer:
To find the number of moles we must first calculate the molar mass( M) of Fe2O3
Molar mass = mass / number of moles
M(Fe2O3) = (55.8 ×2) + (16×3)
= 111.6 + 48
= 159.6 g/mol
number of moles = mass / molar mass
= 125g/159.6g/mol
= 0.783mol
Hope this helps
The neuron becomes more positive. This can lead to the neuron reaching threshold and then initiate an action potential. When the sodium channels are NOT functional, the sodium can not enter and depolarize it. Therefore the threshold can not be met and action potential will not occur. If the sodium channels are inactive in a nociceptive neuron (carries information about pain), then it will prevent you from feeling pain.
increased global populations would probably be a big one
