Metabotropic receptors exert their actions by: A. Stabilizing heterotrimeric G-proteins B. G-Beta/Gamma subunits acting as transcription factors C. G-alpha subunits stimulating the production of a second messenger D. Direct interaction with docking proteins E. Stimulating reverse pumping of transmitter from synaptic terminals

Option C.

G - alpha subunits stimulating the production of second messenger

Explanation:

Metabotropic receptor is a type of receptor in the Eukaryotic cells that exerts it's action by producing a second messenger. They do not change channels but they exerts it effect by binding and stimulating G protein to produce a second messenger. They can either close or open channels in cell membrane. They are found at the surface of the cells or vessicles.

yes its like the dead sea which is full of salt which makes you stay afloat

so yes an egg will float in salt
