Answer:
Diffusion
Explanation:
Diffusion is the movement of a substance (majorly liquids and gases) from a region of high concentration to a region of low concentration. Liquid and gases excluding solids can undergo diffusion because of their ability to move randomly. Diffusion is driven by a gradient in concentration.
For example gases can easily diffuse quickly and easily into another gas, because of its ability to move randomly. The foul air from the back room (higher concentration) was able to quickly spread into the clean air at the front row (low concentration) by diffusion
The fact that science helps your body move nd improve, physical activity requires your body to move which also includes science might not be much help, but it includes physical science
Eeg, MRI, CT, UTI are all diagnostic tests performed in an ER..
