Answer:
B. O2 is reduced when it accepts electrons and forms water.
Explanation:
During cellular respiration water is formed when oxygen receives electrons and picks up protons at the conclusion of the electron transport chain. The electron transport chain will stop functioning if there isn't enough oxygen to receive electrons (for example, because a person isn't breathing in enough oxygen), and ATP will no longer be created by chemiosmosis. Cells can't carry out the reactions they need to function if they don't even have enough ATP, and they may perish after a long period of time.
<span>In the laws of mathematics, especially in rounding off digits, you
should take note of the digit following that number no matter how long or short
a number is. If the numberis preceded by numbers between 0-4, the number does
not change. However if its is preceded by numbers between 5-9, add one to the
number. For example, 145698. If it is rounded off to the nearest hundreds,
since 9 is the number after 6, add 1 to 6 and it becomes 145700. If it is
rounded off to the nearest hundred thousands, since 4 is the number after 1,
you do not add, the number stays the same and it becomes 100000</span>

Answer:
Heating the CuSO4. 5H2O crystals causes then to loose the water of crystallisation that is the 5H2O part. It becomes anhydrous copper sulphate. Its colour changes to white from blue.
