Which organ systems are used to the body shiver?
a.) circulatory and respiratory
b.) nervous and muscular
c.) circulatory and muscular
d.) respiratory and nervous

The correct answer is option B

The temperature of the body is maintained by the certain actions that the body does in extreme conditions to maintain the temperature about 98.6°F.

If the body is in chilling conditions then there are chances that the body will be in hypothermia condition and to control the temperature the brain gives the signals to the muscles of the body to contract and expand very speedly.

When the surface of the body gets too chilly then the skin receptors sends the signals to the brain which gives signals to the muscles to shiver and in extreme case the chattering of teeth also takes place.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
