Answer:

            Four electrons are present in the valence shell of Silicon.

Explanation:

                   Valence shell electrons are those electrons which are present in the outermost shell of an atom. These valence shell electrons are responsible for in the formation of bonds with other atoms.

                   Silicon having atomic number 14 has fourteen electrons in its neutral state and has the electronic configuration as follow;

                                              1s², 2s², 2p⁶, 3s², 3p²

In given configuration the valence shell (outermost shell) is 3 and the number of electrons present in it are four i.e. 3s² and 3p² (2 + 2 = 4) respectively.

Determine the correct amino acid sequence of a heptapeptide (a small peptide containing seven amino acids) on the basis of the f
vova2212 [387]

Answer:

a. Leu-Ala-Arg-Phe-Val-Val-Lys .

Explanation:

Hello.

In this case, considering the given data, we notice that the amino acid has a N-terminal Leu, that is why we first discard d. Moreover, considering the data (iii) and (v) we can infer that there are going to be two fragments by which it is possible to reason the proper sequence:

(iii): the amino acid has one section composed by Lys-Phe-Val-Val and another one by Ala, Arg, Leu that is why e is also discarded.

(v): the other two fragments are Ala, Arg, Leu, Phe, that is why b is discarded.

(iii) and (v): given the aforementioned fragments, we can combine them and therefore discard c, that is why the correct sequence is:

a. Leu-Ala-Arg-Phe-Val-Val-Lys .

Best regards.
