... Sharks are osmoregulators that maintain high internal salt concentrations. This means: a) They actively remove and retain salt from the surrounding seawater. b) They have no need to adjust their internal osmolarity as long as they are in salt water. c) They constantly need to intake water to maintai ...

Signal transduction
Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. In turn, this receptor triggers a biochemical chain of events inside the cell, creating a response. Depending on the cell, the response alters the cell's metabolism, shape, gene expression, or ability to divide. The signal can be amplified at any step. Thus, one signaling molecule can cause many responses.
