Answer
b. Regulate the diet of the affected persons to severely limit the uptake of the amino acid.
Explanation:
<u>This is the effective way of managing PKU, if diet is not regulated, the blood plasma Phenylketonuria levels continue to build up from usual protein consumption. This leads to toxicity of the brain and brain dysfunctions. Nausea constipation, fatigues, health headaches are some of the results of the build up</u>.
Therefore to reduce the blood build up of phenylalanine and thus PKU; Special diet formulas rich in essential amino acids, and other needed nutrients which may be absent in phenylalanine low diet should be adopted. Amino acids substitutes notably Tyrosine which is lacking from failure of phenyalanine breakdown in phenylketouria is heavily supplemented. Tyrosine is important in brain function for alertness, focus,nervous communication.
The adoption of protein substitutes diet or regulated amino acid diet is very important because , all the needed amino acid are available , thus protein catabolisms which may trigger phenylalanine build up from muscles and liver storage withdrawal is prevented thus stabilizing its blood concentration.

The proof that cells only come from other cells
He proved it by his "swan-necked flasks" in which nothing formed in sealed flask whereas many organisms were there in open flask.
So, in short, option D is your final answer!
Hope this helps!

Cerebellum; The cerebellum is located at the back of the head. Just in case you need to know where it is located at :D
1. PbO is a possible formula units, since O has charge of 2- and Pb can have a charge of 2+ or 4+, if it uses the 2+ ion, the charges will balance out to form PbO. Li+ and B(3-) would have Li3B, Al(3+) and Pb(2+) are both positive charges and would not balance out, Cl- and O(2-) are both negative charges and would not balance out.
2. Iodine is a halogen, so it has a charge of -1. Calcium is an alkaline earth metal in Group 2, so it has a charge of 2+. Therefore, if they were to form a formula unit, the resultant would be CaI2 (2 iodine atoms of 1- charge are needed to balance out the 2+ charge on the calcium atom).
3. Strontium is an alkaline earth metal with a charge of 2+, while phosphorus has a charge of 3-. Therefore, to balance the charges out, we would need 3 atoms of strontium and 2 atoms of phosphorus. This would give the formula unit of Sr3P2.
