Answer:A. Circulatory system
Explanation:
After food get digesting the The nutrients gets transported to cells by the blood stream.
The anode is the electrode where the oxidation occurs.
Cathode is the electrode where the reducction occurs.
Equations:
Mn(2+) + 2e- ---> Mn(s) Eo = - 1.18 V
2Fe(3+) + 2e- ----> 2 Fe(2+) 2Eo = + 1.54 V
The electrons flow from the electrode with the lower Eo to the electrode with the higher Eo yielding to a positive voltage.
Eo = 1.54 V - (- 1.18) = 1.54 + 1.18 = 2.72
Answer: 2.72 V
Explanation:
Oxygen - 65.0%
Carbon - 18.5%
Hydrogen - 9.5%
Nitrogen - 3.2%
Calcium - 1.5%
Phosphorus - 1.0%
Potassium - 0.4%
Sulfur - 0.3%
Sodium - 0.2%
Chlorine - 0.2%
Magnesium - 0.2%
Others < 1.0%
The above is the elements present in the human body. They compose of almost all the 20 first elements on the periodic table. The first 20 elements are seen on all sides of the periodic table.
Answer:
The red star denotes the mainshock epicenter of the 2011 Tohoku-oki earthquake (Mw 9.0). The jagged black line denotes the Japan trench. The mechanism of great megathrust earthquakes is influenced by the frictional properties, structure and composition of the plate boundary fault10.
