Answer:
See the answer below
Explanation:
Person X is feeling a burning sensation in several muscles<u> because of the accumulation of lactic acid due to inadequate oxygen in their system.</u> When oxygen becomes inadequate during exercises, anaerobic respiration takes place to augment the oxygen shortage and this leads to the production of lactic acid which accumulates up in the muscles and gives a burning sensation.

Person Y does not feel any burning sensation in their muscles <u>because oxygen is adequate in their system and they do not need to respire anaerobically.</u> <em>Person X exercise regime must have been more rigorous than that of person Y.</em>
Responding to the environment.
Kathy's medical history indicates that she is suffering from Multiple Sclerosis (MS). MS is a disorder of the central nervous system (CNS) and it is mediated and triggered by the immune system. The immune system attacks and destroys the insulating myelin cover of nerve cells of the CNS, causing severe disruption of the functions of the CNS. The most common symptoms of MS include visual, motor and sensory problems.
Kathy's medical problems are related to both her sensory and her motor neurons. She suffered from loss of hearing and experienced feelings of numbness and tingling in some parts of her body. These symptoms are related to her sensory neurons. There are several different kinds of sensory neurons, depending on the stimuli that they are receiving (smell, taste, hearing, vision, temperature, mechanoreceptors etc) and they all participate in the process of sensory transduction. She also suffered from muscle weakness, which caused her inability to get out of bed and walk properly. Her motor neurons are implicated in these symptoms. Motor neurons are the nerve cells responsible for activating muscle cells.
