Answer:
because the body requires a higher supply of oxygen
Explanation:
Cellular respiration can be divided into two different metabolic processes: aerobic respiration which needs oxygen (O2) and anaerobic respiration (without O2). The aerobic cellular respiration is produced when glucose molecules react with O2 in order to form ATP, the energy currency of the cell. Aerobic cellular respiration is the main source for generating ATP. During exercise, the requirement of O2 will be higher because the cellular respiration rate is increased in order to produce more energy (ATP). In consequence, during physical activities, it is required have to breathe faster to supply this O2, which enters into the lungs to be transported to all the cells through blood circulation.
 
        
                    
             
        
        
        
A Genetic cross also cross breeding is the deliberate breeding of two different individuals that results to offspring that carry part the genetic material of each parent. A monohybrid  cross is the breeding of two organisms that differ in a single trait.  A hybrid is an offspring from a cross between parents and has different phenotypes for a specific trait. 
        
                    
             
        
        
        
People are often able to live in a coma for several years because parts of the body that are not under conscious control continue to function. This situation best reflects the importance of the
A) central nervous system
B) autonomic nervous system
C) somatic nervous system
D) forebrain
Answer:
B) autonomic nervous system
Explanation:
The autonomic nervous system is a part of the peripheral nervous system. It comes under the motor division of the peripheral nervous system. The function of this division of the nervous system is to deliver the motor information from the central nervous system to the smooth muscle, cardiac muscle, and glands.  The responses produced by these muscles and glands are not controlled by the will or conscious of the individuals.  
Due to the functioning of the autonomic nervous system, the person under the coma could perform the activities such as breathing, pumping of heart to deliver the oxygen to the body cells, etc. and stay live.
