True, all of them are true
Answer:
66986.51 g/mol
Explanation:
According to this question, Hemoglobin- an oxygen carrying compound in the blood, is found to contain 0.3335% iron (Fe) by mass.
* One molecule of hemoglobin contains four atoms of iron
If 1 atom of Fe = 55.85g/mol
Then 4 atoms = 4 × 55.85 = 223.4g/mol
So there are 223.4g/mol of Fe in one molecule of hemoglobin
If hemoglobin contains 0.3335% iron by mass, this mathematically means that:
223.4g/mol of Fe ÷ molar mass of hemoglobin = 0.3335%
That is;
223.4/M.M = 0.3335/100
Cross multiply
0.3335 M.M = 22340
M.M = 22340 ÷ 0.3335
M.M = 66986.51
Hence, the molar mass of hemoglobin is 66986.51g/mol.

Answer:
Camouflage
If you look closely, you will notice there is some type of insect camouflaging into the plant to hide from something.
