They often respond to Quorum sensing which is determined by the cell density. Bacteria cells secrete molecules that can be detected by other bacteria, Quorum sensing allows bacteria to sense the concentration of these signalling molecules to monitor the local density of cells. It used by bacteria to coordinate certain behaviors , such as the production of biofilms.

Explanation:
Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s)
Earthquakes are mainly known to occur at plate boundaries where plates converge, diverge or slide past each other. Earthquake activity sometimes accompany volcanic eruptions but these too are concentrated around some plate boundaries (convergent, divergent).
Smaller earthquakes are known to occur in intra-plate regions, away from margins. These occur simply because of stresses being built up in rocks. The crust is solid and rigid and it floats on the mantle which is a curved surface like the crust.
This is the process of making glucose in plants. Photosynthesis goes through two individual stages:
Stage 1: Light dependent reaction (depends on the presence of light; it can’t happen in the dark)
Stage 2: Light independent (dark reaction) (works in the absence of light, but calling it a dark reaction might be misleading; It can just as well happen in the presence of light).
