An atom consists of the nucleus (a combination of the proton and neutron) and the electron which orbits the nucleus.
Answer:
B. 5.9 X 10^9
Explanation:
For this question, we assume the following:
•2.3 x 1014 inches is actually 2.3 x 10^14 inches.
•3.9 x 104inches is actually 3.9 x 10^4inches
We now calculate thus;
The average distance in km would be 2.3 x 10^14/3.9 x 10^4
= 0.59 X 10^10.
Therefore, we have;
5.9 X 10^9km.
ADH binds onto the cells of the collecting duct and makes them more permeable to water, thus more water is reabsorbed by osmosis back into the blood. The blood becomes more dilute and the urine more concentrated
