Answer:

Random mutations led to evolution of pesticide resistance genes in bed bugs.

Explanation:

Random mutations in genome of bed bug imparted them the pesticide resistance. Since the bed bugs having the mutation of pesticide resistance were able to survive under presence of pesticides, this variation was favored by natural selection. The bugs with pesticide resistance transmitted this trait to their progeny. In time, the bed bug population consisted of most of the bugs having the pesticide resistance.

lutik1710 [3]

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.
