Answer : The number of iron atoms present in each red blood cell are, 
Explanation :
First we have to calculate the moles of iron.

Now we have to calculate the number of iron atoms.
As, 1 mole of iron contains
number of iron atoms
So, 0.0519 mole of iron contains
number of iron atoms
Now we have to calculate the number of iron atoms are present in each red blood cell.
Number of iron atoms are present in each red blood cell = 
Number of iron atoms are present in each red blood cell = 
Number of iron atoms are present in each red blood cell = 
Therefore, the number of iron atoms present in each red blood cell are, 
Answer: here is a description of what they look like since I cannot see the diagram.
Mitochondria- wavy line
Ribosomes- little dots
Chromosome- X
Nucleus- Circle with bite taken out of it
Endoplasm- Bubble
Nuclear membrane- Outer layer/bubble
Golgi-wavy circle thing
Vacuole- Bigger circle (but not nucleus)
Cytoplasm- its the jelly on the inside
Cell wall- only in plant cells, looks like a box
Cell membrane- The outmost part of the animal cell, the barrier.
I sure hope this helps!!!
