What component of amino acid structure varies among different amino acids?
NISA [10]
<h2>Answer </h2>

The components of the r group of amino acid structure varies among different amino acids

<u>Explanation </u>

As the functional group for amino acids is as:

R-CH-COOH

  I

NH2

only R differs so amino acids also differs. If R is “H” then amino acid is glycine and if R is “CH3” then amino acid is alanine. Hence, R is different for different amino acids. Other components as alpha carbon ( C ), carboxyl group ( COOH ) and amino group ( NH2 ) is fixed for every amino acid.

pochemuha

  • Based on the exam findings as well as the loss in functionality of the ankle, an ankle sprain can be categorized as grade I, II or III.
  • In the given situation the 14-year-old girl has a grade II ankle sprain which is characterized by an incomplete tear of the ligaments along with moderate pain (as she rates it 5/10), moderate tenderness, loss of range of some functions, and swelling.

A conservation plan could proceed with a single 20-square kilometer habitat preserve or with two habitat preserves, measuring a
Aleksandr [31]

A conversational plan with two habitat preserves, measuring a total of 20 square kilometers combined will preserve more species because this cause segregation of species based on their adaptability towards a safer and secure environment. For example if a lion and deer try to live in the same conservation area, then it’s obvious that the life of deer is always at risk. But in cases of segregated preserved areas both herbivorous and carnivorous animals can live separately. Also if there is special inclination of one species towards other then also these two species can live separately.  

Segregation also enhances the diversity in the sense that it could lead to a new ecosystem with a new ecological balance within it. Conservation biologists focus on these areas as they claim that  where the greatest number of unique species can be found and protected with in the large number of reserve areas with the least amount of effort
