Answer:
about 5 billion years ago
Explanation:
Our solar system formed about 5 billion years a go from a dense cloud of interstellar gas and dust.
A possible explanation of a scientific question based on observation
The solution for the problem is:
Since there is $120 deductible, you get to pay…$2345 - $120 = $2225.
But since the insurance covers 70%, so you will only pay the 30%, so it is:30% x 2255 =30/10 * 2225 == $667.50 would be the amount you will be paying.
Do you mean ion pumps in the membrane of cell?
If so, then ion pumps maintain an electrochemical gradient across the membrane.
Answer:
Resistance = 30 Ω
Explanation:
The resistance of an electric circuit = 
voltage = 24V
current (I) = 0.80A
Therefore, R = 
R = 30 ohms
