Aspartate + a- keto acid >> Oxaloacetate + a amino acid
This reaction is occur because the a- keto acid in the equation can come from any amino acid, the 15 N from aspartate is rapidly transferred to other amino acids.
15N is symbol use as the isotope of nitrogen with mass number 15. comprises of 0.4 % of stable nitrogen found, so the relative abundance of each in amino acid is simply a reflection of how much is found in nature in general.
This isotopes is enrichment of the labelled amino acids was determined following a previously developed procedure comprising by determination of the spectral purity of the selected natural abundance amino acids.

Answer:
Concerts, sports games, and political rallies can have very large crowds. When you attend one of these events, you may know only the people you came with. Yet you may experience a feeling of connection to the group. You are one of the crowd. You cheer and applaud when everyone else does. You boo and yell alongside them. You move out of the way when someone needs to get by, and you say “excuse me” when you need to leave. You know how to behave in this kind of crowd.
It can be a very different experience if you are travelling in a foreign country and find yourself in a crowd moving down the street. You may have trouble figuring out what is happening. Is the crowd just the usual morning rush, or is it a political protest of some kind? Perhaps there was some sort of accident or disaster. Is it safe in this crowd, or should you try to extract yourself? How can you find out what is going on? Although you are in it, you may not feel like you are part of this crowd. You may not know what to do or how to behave.

Answer:
Option D, Number of limbs
Explanation:
Options for the question
a. Birth weight
b. Hair color
c. Number of offspring
d. Number of limbs
Solution
Variation within a species is caused due to genetic differences governed by varying allele frequencies and duet to environmental factors that somewhere effect the expression of the genetic potentials thereby causing phenotypic variation.
Number of limbs is a physical characteristics, very unlikely governed by genetic variation. While factors such as hair color (grey, black, white etc.), height (tall, short, medium) etc. are governed by genetic variation as a result of which they have several phenotypic variations.
Hence, option D is correct
In nondisjunction, if members of a pair of homologous chromosomes do not move apart during meiosis I or sister chromatids fail to separate during meiosis II, this means one gamete receives 2 of the same kind of chromosome and i<span>f either one of these abnormal gametes unites with a normal one at fertilization, the zygote will also have an abnormal number of particular chromosomes; which is known as an aneuploidy.</span>
