Answer: Phenylanine; Lysine

An amino acid mixture consisting of alanine, phenylalanine, and lysine is to be separated by normal phase HPLC. The stationary phase is polar and the mobile phase is a nonpolar solvent. The first amino acid to be eluted will be Phenylanine. The last amino acid to be eluted will be: Lysine

Explanation:

In normal phase HPLC (High performance liquid chromatography), the polar stationary phase would retain the less nonpolar amino acids (alanine and lysine) while the nonpolar mobile phase would permit the quick elution of the aromatic amino acid, phenylanine. Thus, phenylanine is first eluted.

This is then followed by the elution of the amino acid with nonpolar side chain, alanine. Thus, alanine is the second to be eluted.

Lastly, the positively charged amino acid, lysine will be released by the stationary phase. Thus, lysine is the last to be eluted

Congenital analgesia is a rare autosomal recessive trait. What is the likelihood that the first two offspring of a cross between
telo118 [61]

The likelihood that the first two offspring of the cross will have congenital analgesia would be 1/16

<h2>Autosomal Recessive Traits</h2>

For autosomal recessive traits, two recessive alleles are needed for the trait to manifest while one recessive allele means heterozygosity.

In this case, let us assume that congenital analgesia is represented by the allele b; heterozygous individuals will, thus, be Bb.

            Bb    x    Bb

          BB   Bb   Bb   bb

Probability of producing unaffected offspring = 3/4

Probability of producing affected offspring = 1/4

Likelihood of the first two offspring having congenital analgesia = probability of first having congenital analgesia and the second having congenital analgesia

    = 1/4 x 1/4

        = 1/16

Gemiola [76]
The reaction to produce soap can be completed by cooking animal fat with a very strong solution of SODIUM HYDROXIDE.
This process is called saponification. Chemically, animal fat and strong solution of sodium hydroxide or potassium hydroxide mixed together to produce soap and glycerol.<span />
