I would go with hypothesis because I never heard any of the other answers in Bio and a hypothesis is an educated guess so it means what you already know and it’s an observation (I hope this helped!!)
The central nervous system has two functions. One, where the brain is, is to be the center of thoughts and the interpreter of outside influences, while the spinal cord connects all parts of the body with the brain.
On the laboratory bench right in front of you, there is a bone. You can tell that it has an articular surface that is smooth and just slightly concave. This skeletal feature would be referred to as a Facet.
<h3>What is the composition of human bone?</h3>
A transcription factor collagen forms the structure of bones, and calcium phosphate, a mineral, gives the framework strength and hardness. When other body parts require calcium, bones release some of the calcium they have stored into the blood.
<h3>Why are bones so durable?</h3>
A living, developing tissue is bone. Collagen, a polypeptide that provides a soft structure, and calcium, a mineral that gives strength and hardness, make up the majority of its composition. Together, these factors give bone the strength and flexibility it needs to withstand stress.

Answer: the structure of an atom: At the center of the atom, there is a very small region called the nucleus. This area makes up most of the mass of the atom.
The area around the nucleus is called the electron cloud. This area makes up the majority of the volume of the atom. The electron cloud is mostly empty space.
