Answer:
The correct answer is c. Fatty acids
Explanation:
There are four major types of macromolecules present in nature and that are carbohydrates(polysaccharides), proteins, lipids, and nucleic acids. These macromolecules are polymers and are made up of monomer units.
The monomeric unit of polysaccharides is mainly glucose, of protein is amino acids, of nucleic acid is nucleotides and the monomeric unit of lipid is fatty acids. Ribosomes are macromolecules because it is made up of RNA and proteins.
So fatty acid is a monomer which joins together to form large macromolecules like lipids. Fatty acids are made up of a hydrocarbon chain which have one attached COOH group at the terminal position.
Therefore the correct answer is c. Fatty acids.

The phase in the cardiac cycle when the mitral valve is closed and the aortic valve is open is the systolic ejection phase (Option D). It is the second phase of the ventricular systole.
The cardiac cycle is a sequence of contraction and relaxation of the atria and ventricles to pump blood throughout the body.
This cycle (cardiac cycle) can be divided into two major periods: diastole and systole.
The diastole is when the heart relaxes and refills with blood, while the systole is when the heart contracts and pumps blood.
The systolic ejection phase is the second phase of the ventricular systole where blood is pumped from the ventricle.
