Planting the same crop in the same place each year zaps nutrients from the earth and leaves soil weak and unable to support healthy plant growth. Because soil structure and quality is so poor, farmers are forced to use chemical fertilizers to encourage plant growth and fruit production.
pretty sure you are wrong fella , the answer is actually c) high winds lol your welcome
Ill need to know what change you predicted, but natural selection can contribute to the change by allowing the organism with the mutation (advantage or disadvantage) to either parish or aid in its survival, resulting in that mutation to be passed on the other generations through breeding
<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.
