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.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

the answer is "a.) well–developed vascular system."
