Why is it important for signal transduction systems to trigger a rapid response within a cell and be able to be shut down quickly?

-All signal transduction cascades are shut down immediately so as to prevent the cell from mounting a response.

-Cells are unable to respond quickly to hormones, and therefore signal transduction cascades always occur over a long time.

-Cells have to be able to function alone, because they are unable to work together in a coordinated fashion.

-Cells often have to respond very quickly to changes in their internal and external environments.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
