Carbohydrate is the major source of energy without which one cannot live. It is because carbohydrate is broken down to form instant energy in the form of glucose which can be converted into ATP and thus used for the regular functioning of the cell. Other forms of energy like proteins, vitamins, and minerals are the extra components that are not directly involved in the formation of energy.

Crystals of calcium oxalate, starch grains, stone cells with lignified walls, brown tannin cells, and crystals of gypsum are present in the cells of Ficus benghalensis, they belong to family Moraceae. The presence of different crystals is the characteristic feature that distinguishes families from each other.

Energy storage molecules are those molecules which store energy in the form of covalent chemical bonds. Some molecules like glycogen (carbohydrate) and triglycerides (lipids) are synthesized by the cells and they are stored for the later release of energy. So, the correct answer is "both lipids and carbohydrates".

Ceramic solids are composed of inorganic compounds, usually oxides of chemical elements. They are chemically inert, and often are capable of withstanding chemical erosion that occurs in an acidic or caustic environment. 

Proteins are the polymers of amino acids held together by peptide bonds. Carbohydrates are polyhydroxy aldehyde or ketones or their derivatives. Nucleic acids are polymers of nucleotides held together by phosphodiester bonds. Lipids are the chemically diverse group and mostly have long hydrocarbon chain. Thus, the correct answer is B.

Amylase is peptide hormone and consists of amino acids as monomer subunit. Glycogen is homopolysaccharide of D-glucose while lipids having attached phosphate groups are called as phospholipids. Polysaccharides are polymers of simple sugars (single polyhydroxy aldehyde or ketone unit). Ribonucleic acid is a polymer of ribonucleotide monomers. Thus, the correct answer is A.

All ores are minerals but vice-versa is not true.

Silicon are the most abundant elements in the earth's crust. All the rocks and minerals are composed of it.

A stalactile is a type of formation mineral that hangs from the ceilings of caues hot springs and other.
