A monomer is made up of a nitrogenous base, a five-carbon sugar, and a phosphate group bonded together. Hence, option A is correct.
<h3>What is a lipid?</h3>
A lipid is any of various organic compounds that are insoluble in water.
The smallest units of DNA are called nucleotides. These are organic molecules that serve as building blocks of DNA and RNA. They are monomers or subunits of nucleic acids like RNA and DNA. It is made up of a nitrogenous base, deoxyribose (five-carbon sugar), and at least one phosphate group.
They serve an important role in the metabolism of cells because they carry packets of energy in the form of nucleoside triphosphates (e.g. ATP, GTP, CTP, and UTP). They also play an important factor in cell signalling through enzymatic reactions and productions.
Hence, A monomer is made up of a nitrogenous base, a five-carbon sugar, and a phosphate group bonded together.

The production of carbon-14 occurs to a large extent in nuclear reactors.
Hence, option D is correct
<h3>What is carbon-14?</h3>
Carbon-14 is a weakly radioactive isotope of Carbon; also known as radiocarbon, it is an isotopic chronometer.
Carbon-14 is produced in the stratosphere by nuclear reactions of atmospheric nitrogen with thermal neutrons produced naturally by cosmic rays (with the highest production rate 10 to 13 miles above Earth's poles), as well as by atmospheric nuclear weapons testing in the 1950s and '60s.
Hence, option D is correct

Answer:
n is the principal quantum number, it specifies the energy and average distance from the nucleus
l is the orbital quantum number, it specifies the subshell/orbital shape
ml is the magnetic quantum number and specifies the orbital orientation
Explanation:
The Schrödinger wave equation is solved for the hydrogen atom to yield three sets of quantum numbers.
The principal quantum number corresponds to the energy level in the Bohr model and also shows the average distance of the electron from the nucleus.
The orbital quantum number reveals the subshell where an electron is found as well as the shape of the orbital. E.g p-orbitals are dumbbell shaped.
The magnetic quantum number shows the orientation of an orbital in space. Its values range from -l to +l
