Answer:
The exoskeleton helps support movement by working with the muscles.
Explanation:
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>

En el proceso de síntesis, los aminoácidos son transportados por ARN de transferencia correspondiente para cada aminoácido hasta el ARN mensajero donde se unen en la posición adecuada para formar las nuevas proteínas.
