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.
Answer:
a) contain DNA combined from two different organisms
In order to identify the most recent common ancestor of an animal, the physical and genetic makeup of the organisms must be compared. The two organisms must have striking similarities in order to be considered as closely related.
Despite the difference in their size, the domestic ferret has a great resemblance with the features of an Eastern European polecat. In addition, they have the ability to cross-breed with polecats. Therefore, the most recent ancestor of the ferret is the Eastern European polecat.
This took a long time to type cuz I am a slow typer. But I hope I got the answer correct! Hope you have a great day!:)
Correct me if I'm wrong but I believe it is the Gravity (or Gravitational Pull) from the Sun.
