Well to begin with this process is called genetic engineering, the scientists altered the DNA of the chickens instead of altering a protein already in the chickens because when you alter the DNA the offsprings of the chicken will will have the same qualities while if you only alter the protein already in that chicken only that chicken will be able to do the job
1. Moles Fe = 209.7 g/ 55.847 g/mol= 3.75
The ratio between Fe and CO is 2 : 3
Moles CO = 3.75 x 3 /2 = 5.63
<span>Mass CO = 5.63 mol x 28.01 g/mol= 157.7 g
2. </span><span />2Na + 2H2O --> 2NaOH + H2<span>atomic weight of sodium is 23 48.7/23 = 2.12 moles of sodium
2.12/2 x 24 = 25.44dm^3 hydrogen = 1.06 moles
so multiply it by Avogadro's number1.06 X 6.02x10^23 = 1.204x10^24 molecules of hydrogen

Answer:
This leads to dilation of the walls of the respiratory lower respiratory tracts.Thus maximum volume of air is conducted (inhaled) through these tracts to reach the lungs with each inspiration. The rate of diffusion of oxygen across the bronchi walls also increases with the dilation; with consequent increases in perfusion pressure of oxygen with Hb in the blood.
