Which of the following is not a polyner glucose tryglicerides starch and dna

Glucose

Explanation:

A polymer is a macromolecule composed of many repeating subunits.

Triglycerides are made of three fatty acids and glycerol, they are polymers of fatty acid molecule monomers.

DNA molecules are polymers of nucleotides.

Glucose is a monomer. When it polymerizes it forms starch or cellulose.

Therefore, the only option that is not a polymer is glucose.

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.
