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.
C) Secure the scene, take photographs, take notes, search for evidence, collect evidence, send evidence to the laboratory for testing.
The cytoskeleton of a cell allows the cell to be flexible. Our human skeletons allow <em>us </em>to be flexible.
Correct answer: A). The current hypothesis of the evolutionary relationships between organisms
The tree of life is a metaphor that expresses the idea that how life is related to ancestors. Charles Darwin first uses this in the modern biology. It is an evolutionary tree that depicts the relationship between various biological entity. It holds the data that are collected from RNA, DNA and protein analysis. It shows the current hypothesis about the evolutionary relationship among the taxa.
Hence, the correct answer would be option A.
Answer:
1) Recursive definition: 
2) At the beginning of the 4th interval
Explanation:
1)
The initial population of the bacteria at time zero is
Here we are told that the reading is taken every two hours; we call this time interval "n", so
And also, after every time interval n, the number of bacteria has tripled.
This means that when n = 1,
And when n=2,
Applied recursively, we get
And substituting p0,
(1)
2)
Here we want to find at the beginning of which interval there are
bacteria.
This means that we can rewrite eq.(1) as
By simplifying,
Which means that
However, this means that the number of bacteria is 1,350,000 after 3 time intervals; therefore, at the beginning of the 4th interval.
