Which of the following correctly describes the role of biomolecules in energy storage ?

Biomolecules are crucial to the storage of energy energy in the body.

Biomolecules conserve energy using covalent chemical bonds.

Explanation

A covalent bond in chemistry refers to a chemical bond that is formed when two atoms share a pair each of electrons.

So some of these molecules which have high energy (such as glycogen and triglycerides) are able to keep or store such energy in the form of covalent chemical bonds. Examples of energy-rich biomolecules are:  

Cells synthesize such molecules and store them for later release of the energy.

B. Carbohydrates are used for short-term energy storage, and lipids are used for long-term energy storage.

Explanation:

Humans and animals use carbohydrates for short-term energy storage and are stored as glycogen which can be broken down into glucose when energy is needed.

Lipids are used for long-term energy and are stored as fats in the body. These fats can be broken into fatty acids when the body needs energy.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

they had the law tat factories that produces smoke cannot be built near residential buildings.

building of proper sewage system was done to ensure that the waste is carried away from the humans so that they do not get diseases from it.

also they built water systems to provide water in those areas which are drought prone.
