Protein synthesis is a process that is generated within cells where different organelles and genetic components are involved through which proteins are generated.

The biosynthesis of proteins will be given by different parts, beginning with the translation of the genetic material. It will be given by different steps:

1. mRNA binds to ribosomes and the aminoacyl-tRNA to be associated to the first codon of the mRNA is associated.

2. The elongation of the polypeptide chain occurs, in which the amino acids are joined

3. The elongation is finished when the termination codons are reached.

4. The translation components are released and post-translational modifications are started.

5. The folding, glycosylation and modification of amino acids occur

6. Finally, the protein is released to generate its function

The molar mass of the substance is needed to convert between the moles of a given sample of a substance and its mass in grams.

A compound's molar mass, which is measured in grams per mole, specifies how much of a given material weighs in one mole. In other terms, the molar mass is the sum of the masses of all the atoms that make up a mole of a certain molecule, expressed in grams. As a result, the molar mass is measured in grams/mole.

The compound's molar mass is expressed in grams per mole, or g/mol. The mass of 1 mol, expressed in the SI as g/mol, is the definition of the molar mass. Example: Water has a molar mass of 18.016 g/mol.

Thus, The molar mass of the substance is needed to convert between the moles of a given sample of a substance and its mass in grams.

When total ammonium ion is 50% dissociated, The pH is 9.25.

Given, the pKₐ of ammonium ion (NH₄⁺) is 9.25.

The dissociation of NH₄⁺ to ammonia (NH₃) and H⁺ in aqueous solution is represented below.

It is stated that the ammonium ion is 50% dissociated in the solution. Therefore the concentration of each species at that instant [if started with 1M conc. of NH4+ (aq)] is summarized as follows:

                                              NH4+ (aq) ⇌ NH3 (aq) + H+ (aq)

Initial conc. (in M)                     1                   -                 -

At 50% dissociation 1-0.5, i.e., 0.5          0.5          0.5

The given value of pKₐ immediately reminds us of the form of Henderson-Hasselbalch equation containing pKₐ , i.e.,

pH = pKₐ + log₁₀ [tex]\frac{[salt]}{[acid]}[/tex]  _ _ _(i)

But, NH₄⁺ (aq) exists as the conjugate acid form, as well as the salt (ionized) form. Hence, we cannot use equation. (i) for our calculations.

Therefore, we need to convert the above value of Kₐ to the equivalent Kb (for NH₃), corresponding to the reverse equilibrium.

This is achieved by using the relation

Kb = [tex]\frac{Kw}{Ka}[/tex]

or,  -log₁₀ Kb = -log₁₀ Kw + log₁₀ Ka

or,  pKb = pKw - pKa = 14 - 9.25 = 4.75

where, pKw = 1 x 10⁻¹⁴ (at 298 K).

Therefore, pKb of ammonia (NH₃) = 4.75

Now, we need to use the form of Henderson-Hasselbalch equation which uses Kb; which is in fact

pOH = pKb + log₁₀ [tex]\frac{[salt]}{[base]}[/tex]  _ _ _(ii)

where the salt is NH₄⁺, and the base is NH₃. Further, we know that

Kw = [H⁺][OH⁻]  or,  pOH + pH = pKw = 14    or,   pOH = 14 - pH

Substituting this relation in eq. (ii) gives

14 - pH = pKb + log₁₀ [tex]\frac{[NH4+]}{[NH3]}[/tex]

or, pH = 14 - pKb — log₁₀ [tex]\frac{[NH4+]}{[NH3]}[/tex]

As calculated, pKb = 4.75, [NH₄⁺] = 0.50 M, while [NH₃] = 0.50 M, assuming we start with a conc. of 1M NH₄⁺. Hence,

pH = 14 – 4.75 – log₁₀ [tex]\frac{0.50}{0.50}[/tex]

     = 9.25 - log₁₀ ( 1 )

     = 9.25 - 0

pH = 9.25

Hence, the pH of a solution consisting of 50% NH₃ and 50% NH₄⁺ will be equal to 9.25.

Magnesium and calcium are 2nd group elements with 2 valence electrons. They are metals in room temperature and easily lose these electrons to nonmetals such as oxygen.

Magnesium is 12th element in periodic table. It is 2nd group element and is a called alkaline earth metals. Its group members are calcium, strontium, and barium.

They contains 2 valence electrons which can be easily lost to a non-metal. Oxygen is highly electronegative element and it contains 6 valence electrons and need two more electrons to achieve octet.

Al is 13th group element it is not as much electropositive as alkaline earth metals. It contains 3 valence electrons and thus it need to lose all these 3 electrons to achieve octet. Hence, Al is less reactive towards O2 in comparison with Mg and Ca.

Neil Bohr used the fluorescent screen and an alpha particle detector to study the structure of an atom.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

The atom as a whole is neutral and stable due to presence of oppositely charged particles.

The electronegativity is n < p < ge < ga.

Electronegativity is a measure of an atom's ability to attract electrons when it forms a chemical bond with another atom. It is based on the Pauling Scale, which assigns values to elements based on their tendency to attract electrons when they form bonds. Electronegativity increases from left to right across the periodic table, and increases from the bottom to the top of the periodic table.

The correct answer is n < p < ge < ga. This is because electronegativity increases as we move down a group in the periodic table and from left to right across a period.
Therefore, the element with the highest electronegativity is at the bottom right corner of the periodic table, which is gaseous, followed by Germanium, Phosphorus, and then Nitrogen.

The concentration measures will change in value as the temperature of a solution changes is molarity. The correct option is 4.

The molarity of a substance refers to how much of it is present in a given volume of solution (M). Molarity is the measure of how many moles of a solute are present per liter of a solution. Molarity is also referred to as a solution's molar concentration.

To find the equation for molarity, divide the volume of solvent used to dissolve the given solute by the number of moles of that solute. M = n V

Since the volume of the solution rises as the temperature rises, molarity decreases. Therefore, molarity is normally affected when therefore is a change in temperature of a solution either when it increases or decreases.
