<h2>Answer:</h2>
The same type of amino acid, means acidic amino acid substitution will leads to normal folding.
The amino acid will be glutamic acid.
<h3>Explanation:</h3>
- Sometimes the amino acids of the same type substitution leads to normal proteins.
- As the acidic group of aspartic acid is responsible for the folding of the protein .
- So if the amino acid is substituted by glutamic acid, it will not leads to any abnormal protein folding.
- Because glutamic acid also has a acidic group which is responsible for folding of protein.
Answer:
C. is unstable, with a short half life
Explanation:
Paracrine hormones are the hormones that act on neighboring cells only. These hormones or chemicals are largely unstable and have a brief life as do not visit the distantly placed target cells. For instance, somatostatin is secreted by D cells of the pancreas. It acts in a paracrine manner and inhibits the discharge of hormones from the neighboring beta and alpha cell.
Likewise, one of the functions of unstable NO gas is to serve as a vasodilator. It is released by epithelium cells and serves to dilate arterioles and relax precapillary sphincters. Then it is degraded.
The answer is b because genes can control sn organisms traits
Many scientists are concerned that the Ogallala aquifer in the United States is being depleted at an alarming rate. The statement that is correct and would state the most likely be a major effect of this aquifer running dry is choice A. It states that many crops would die because irrigation water would be limited.
