Explanation:
Nitric oxide(NO) is a signalling molecule synthesised by NO synthase which is a a transmitter in the nervous system. Once it is produced, it diffuses out of the cell and act on nearby cells.
NO have a life time of few seconds and it is extremely unstable and highly reactive, it action is restricted.

Answer:
There are four subsystem of earth that includes lithosphere, hydrosphere, biosphere and atmosphere.
Ocean is included in hydrosphere and is one of teh largest subsytem in the earth. <u>The two input and output to the ocean subsytem are as following:</u>
- The wind energy (input) transfer to ocean surface affects the motion of water in the ocean and produces waves (output).
- Heat energy recieved from the sun (input) is transferred toward the poles and allows the heat lost to the space (output).
<u>some of the interaction of ocean with other subsytem are as following:</u>
- Interaction between biosphere and hydrosphere (ocean): ocean provide water to living organism for survival and growth.
- Interaction between atmosphere and ocean is water cycle. The water from ocean evaporates through heat (sun) and through rain the water again reaches to the oceans.
