Neutrons have no electrical charge
Answer:
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:
- glycogen and
- triglycerides
Cells synthesize such molecules and store them for later release of the energy.

The iris is composed of muscle layers - an outer layer of longitudinal smooth muscle and an inner layer of circular smooth muscle. The inner circular layer is innervated by the parasympathetic nerves. When these muscles contract, they that cause the pupil to constrict in bright light. the The outer layer of longitudinal smooth muscle is innervated by the sympathetic nerves. When these muscles contract, they that cause the pupil to dilate in dim light.
Chimpanzees have been trained to communicate with humans through sign language. Chimpanzees have relatively large brains and as such have complex social relationships and use simple tools. They can be taught to use sign language and some researchers suggest that they can communicate via this medium at the level of a 4 to 5 year old human.
