Acertain organic compound is made up of the amino acids methionine, arginine, and leucine. which type of organic compound is this? carbohydrate protein nucleic acid lipid

Proteins.

Explanation:

Biomolecules are the organic molecules present inside the living organism. Biomolecules plays an important role in the living organism. Four important biomolecules are proteins, carbohydrates, lipids and nucleic acids.

Proteins are the made of the polymers of the amino acids linked together through the peptide bond. The compounds contains the amino acids methionine, arginine, and leucine. This compound is a protein as it is made up of amino acids.

Thus, the correct answer is option (2).

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
