Answer:
<u>The bacterial cell because it has the largest surface-to-volume-ratio.</u>
Explanation:
The rate of diffusion in and out of a body depends on surface area to volume ratio. The higher the ratio the greater the rate of diffusion and the lower the ratio, the lower the rate of diffusion.
This implies that small organisms like the bacteria cell expose a large surface area to the surrounding when compared to big organism cells. Therefore, small organisms depend on diffusion as a means of transport of foods, respiratory gases and waste products.
Large organisms, in addition to diffusion have trasnport systems to increase the efficiency of diffusion.
The smallest level of organization in the human body is the cell
As for earthquakes, seismograph can be used to monitor tremor activity of volcanoes.
It is very important to predict when a volcano is going to erupt, because it is extremely dangerous if there are people living near that volcano. People need to be informed if they need to evacuate in case of volcano eruption, and seismographs are used to check the tremor.
