<h3>How many amino acids are synthesized?</h3>
For example, humans can only synthesize 11 of the 20 standard amino acids (a.k.a. non-essential amino acid), and in time of accelerated growth, histidine can be considered an essential amino acid.
<h3>Where does amino acid synthesis occur?</h3>
The process of making proteins is called translation and involves the step-by-step addition of amino acids to a growing protein chain by a ribozyme that is called a ribosome.
<h3>Is the amino group the 5 end?</h3>
The 5-prime (5') end of the polypeptide chain that has a nitrogen atom or a 'free amino group. '
Peptide bonds connect all of the amino acids of the chain together. (Norman, 7/22/09) When two or more amino acids are linked together, one end of the resulting molecule has a free amino group.

Answer:
2. High
3. Low
Explanation:
4. Sinking air compresses and heats. As air sinks, air pressure at the surface is raised.
3. As air rises, air pressure at the surface is lowered
Answer:
h = 45 m
g(acceleration due to gravity) = 9.8 m/s^2 or 10 m/s^2
Final velocity ( v ) = 0 m/s
v = ?
we know theirs equation of motion, v^2 = u^2 + 2gh
0 = u^2 + 2(-10)(45) [ The acceleration due to gravity is ALWAYS negative. Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing.]
0 = u^2- 900
900 = u^2
u = √900 = 30 m/s
