Answer:
- Human growth and functioning can be explained by the functioning of the cells.
- Cells are the fundamental units of humans.
- The functioning of the cells in the body determine human health.
Explanation:
The cell is the basic unit of life. Therefore the biochemical activities of the cell at a micro-level will definitely influence overall physiology at the macro level of an organism. For example, the production of Thyroid hormone at the molecular level by the cells in the thyroid glands will influence the metabolisms of all cells in a human being and therefore affect the organism’s overall growth and development.
