<u>Potential energy</u> is the chemical energy stored in the chemical bonds of atoms and molecules.
<h3>What is potential energy?</h3>
Potential energy is the energy stored in the bonds (structural arrangement) of chemical compounds, such as atoms and molecules.
<h3>Characteristics of potential energy</h3>
- The potential energy that a molecule may have is due to the forces of attraction and repulsion with other molecules in its environment.
- An example is glucose, which stores chemical potential energy that the body, through metabolism, transforms into heat energy to maintain body temperature.
Therefore, we can conclude that potential energy is stored in the chemical bonds of molecules.

Cell is a simple unit of life surrounded by a membrane that contains macromolecules and molecules associated with each other.
<h3>What is cell?</h3>
The smallest unit that makes up all living organisms and the tissues of the body. A cell consists of three main parts i.e. the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the cell and its function controls the substances that go inside of cell and out of the cell. A nucleus is the membrane that enclosed organelle within a cell which contains the genetic material. The cytoplasm is the gel-like fluid inside the cell that provides a medium for chemical reaction.
So we can conclude that Cell is a simple unit of life surrounded by a membrane that contains macromolecules and molecules associated with each other.

Q:</span><span>Proteins have a variety of functions within a living cell. Describe at least three of the possible functions of proteins, and explain how proteins can be</span><span>
A:Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.</span>
Answer:
Fish have shown to improve their coloration when exposed to the sunlight. It's also beneficial for the fishes eating algae. Since the sunlight is stimulating algae growth there will be more algae.
