Answer:
The correct answer is - 6.8950.61 gm per mole
Explanation:
Given:
One form of hemoglobin is 0.324% Fe by mass
1 hemoglobin = 4 Fe
Solution:
Molar Mass of iron = 55.85
mass of 4 iron atom = 55.85 * 4 = 223.4 gms
0.324 % correspond to 223.4 gms
100 % correspond to = 223.4 *100/0.324
= 68950.61 gm
MM of haemoglobin = 68950.61 gms = 6.8 E4 gms
Answer:
Explanation:
halocline
wind
dissolved salts
ionic
Coriolis
Convection currents flow due to variations in the temperature and salinity in seawater, which both influence its density. Variations in density in different regions of the ocean will cause water to flow from less dense areas to more dense areas as water heats up and becomes less saline, producing a horizontal convection current. Vertical convection currents can arise as cooler, more saline water sinks, causing warmer, less saline water to rise.
A cell membrane protects a cell from it's surroundings. The cell membrane controls the movement of substances from the outside and inside of cells and organelles.
B) This is false, because enzymes do the complete opposite.
