The giraffe head is higher than its heart so the blood pressure in the head must be lower than in the heart. The pressure is directly related to the density, gravity, and the height. The calculation would be:
<span>P = ρ*g*h
</span>P= 1.05* 10^3 kg/m3 * 9.8m/s2 * 2m= <span>20 580 pascals= 20.58 kpa</span>
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
