In the simulation, the brightness of the guppies is directly related to
how fast they are consumed by predators. This phenomenon is explained
simply and reflects natural selection. The brighter guppies are at a
selective disadvantage due to the ease with which predators are able to
spot them. The darker colored guppies are able to avoid predator better
so they live fore a longer time.

Answer:
Explanation:
Nitrous acid mutation occurs when a Nitrogenous base is replaced by a keto group.
Alanine is replaced by hypoxanthine,
Cytocine is replaced b Uracil
Guanine is replaced by Xanthine.
Nitrous mutation often affects Adenine, Cytocine and guanine. The Nitrogenous base is changed into another substance(keto group)
Alanine at position 65 would be replace by hypoxanthine a keto group which is a form of nitrous mutation.
Other forms of amino acid mutation
Mutation of amino acid nitrogenous base can either be transition or transversion.
Transition is the substitution of a purine base by another purine base. Since purine are Adenine and Guanine
Pyrimidine is cytocine and thymine or Uracil. Adenine can be substituted for by guanine or guanine by adenine
E.G A - G now G - A where Guanine substitute Adenine
Whole transversional substitution can also occur which involve a purine been substitued for by a pyrimidine or pyrimidine by a Purine.
A - G
Now C-G where cytosine substitute Adenine.

Answer:
Two of the qualitative traits that Jamie observed were
1. The cakes with more eggs were darker in shade.
2. The cakes with more eggs were moister.
Two of the quantitative traits that Jamie observed were
1. The cakes made with 3 eggs were 0.25 to 0.5 cm taller as compared to the ones made 2 eggs.
2. The number of cakes made by using either 2 or 3 eggs remained six.
Explanation:
Qualitative research can be described as observations that are made through explorations. Qualitative research best explains the reasons for a particular hypothesis. In the following question, two of the qualitative traits that were observed were
1. The cakes with more eggs being darker in shade than the cakes with less number of eggs.
2. The cakes with more eggs being moister than the ones with less eggs.
Quantitative research can be described as the type of research in which statistical or numbering data is used to explain any hypothesis or observation. Two of the quantitative observations made in the following experiment by Jamie were
1. The cakes made with 3 eggs were 0.25 to 0.5 cm taller as compared to the ones made 2 eggs.
2. The number of cakes made by using either 2 or 3 eggs remained six.
