Describe at least two ways bone functions in protection of the human body

Answers

Answer 1

Answer:

Answer and Explanation:

The human being has a bone system made up of 206 bones that grow and develop in childhood and adolescence. Thanks to these bones, people can stand up and move around. The function of the bone system is to support the body, allow locomotion, and protect the organs. The bones that make up the system are linked through joints and are made up of a class of cells known as osteocytes.

The bones form various cavities that protect the internal organs from possible trauma. For example, the skull protects the brain from hits, and the rib cage, made up of ribs and sternum, protects the lungs and heart. On the other hand, various minerals such as calcium and phosphorus are stored in the bones, not only to provide them with hardness, but to later use them as an input in muscle contraction and other organic processes

B. Organize cells into tissues
C. Use chemical signals to communicate between its cells
D. Change food or sunlight into useful energy

Answers

The answer is C. Homeostasis is the process within a cell which aims at maintaining equilibrium within the cell. All living cells exhibit this process. Homeostasis happens by detecting and responding to slight changes in the normal processes inside the cell. Homeostasis occurs by regulating the movement of substances in and out of the cell to maintain a stable concentration inside the cell. It uses chemical signals to communicate between its cells.
