Answer: Option B
Explanation:
Involuntary functions of the body system; processes taking place in the body that is done without conscious efforts such as digestion, bloodflow, the heartbeat are controlled by the autonomic nervous system which is a part of the peripheral nervous system. 
 
        
             
        
        
        
Answer:

Answer:
Outer Core of Earth
Explanation:
The outer layer of core of earth consists of iron as a major constituent. Due to internal high temperature and low pressure (as compared to the inner core) , the iron in this layer exists as liquid iron. Since the earth is rotating continuously on its axis, the liquid iron is also rotating thereby producing magnetic field. Due to magnetic field , this sphere of earth is known as magnetosphere.

Smart home technology is the general term given to basic home amenities that have been fitted with communication technology, enabling some degree of either automation or remote control. It includes things like Home security systems. Environmental controls, like air conditioning, heating, and lighting.
Explanation:
Environmental controls, like air conditioning, heating, and lighting.A spectrometer is a device for measuring wavelengths of light over a wide range of the electromagnetic spectrum. It is widely used for spectroscopic analysis of sample materials. The incident light from the light source can be transmitted, absorbed or reflected through the sample The solution for space exploration is through using mass spectrometers which are used to identify miniature particles present in space. Mass spectrometers are also used in radioactive and carbon dating. When used with gas chronographs, mass spectrometers detect traces of toxic particles and contaminants in air.
