Explanation:
The sodium hydroxide solution and vegetable oil underwent a chemical change.
<h3><u>Explanation:</u></h3>
The reaction between a base and a fat or fatty acid is called as saponification reaction. Here the base dissociates into the cation and hydroxyl ion. The hydrogen from the fatty acid of the oil reacts with the hydroxyl ion to form water which is basically the neutralization reaction. This cation now reacts with the rest of the fatty acid to form a bipolar molecule which is the soap. During the reaction, the solution becomes cloudy but with time, it again goes back to solution. The cloudyness appears because oil isn't soluble in water based solutions and the base is actually made solution in water.
Here the sodium hydroxide reacts with oil to form water and the soap molecule which is a chemical change.

Explanation:
For the recessive trait to show in the phenotype, the individual has to be homozygous recessive for the gene. Therefore if we designate the allele for White color as <em>r</em> and that of Brown as <em>R</em>;
<em>rr </em>= 16% = 0.16 → This is the gene frequency for recessive population
To find the allele frequency
√0.16
= 0.4
Remember the hardy Weinberg principle of allele; All allelic frequency of a gene adds up to 1 in an ideal population (that observes certain assumptions).
p + q = 1
p + 0.4 = 1
p = 1 – 0.4
p = 0.6
The allelic frequency of Brown hair is 0.6.
The frequency of individuals of a homozygous dominant genotype will be;
P² + 2pq + q² = 1
0.6 * 0.6 = 0.36
