TAQ 2Identify which subject has abnormal blood glucose level.Subject XName the condition that the subject has.HyperglycemiaHow does the condition cause a change in the body physiology and resulting blood glucoselevel?The elevated value of glucose level makes subject X highly prone to the symptoms ofHyperglycemia. The frequent value of high blood sugar above ideal levels can affect thefunctioning of organs and can even damage the nerves and blood vessels. The blood sugar levelmay continue to rise and can result in variety of symptoms such as high sugar level in the urine,increased thirst and frequent urination. The consistent and rapid elevation of sugar level can alsocause diabetic ketoacidosis (Postnov and et.al., 2015). During this condition the ability to storeglucose is reduced. As a result, glucose produced between meals causes high glucose levels.TAQ 3A. Process occurring on touching a hot panOn accidentally touching hot pan our hand is involuntarily snatched away from the pan.When skin comes in contact with the hot object then, skin receptors transmit electrical signals(called nerve impulses) to central nervous system (CNS) through sensory neurons. In CNS(spinal cord) the relay neurons connect with the signal from sensory neuron and motor neuronsof the affected body part (hands). Themotor neurons projecting out of spinal cord cause ourhand to snatch away from the hot pan.B. Events occurring at synapse during impulse transmissionThe interaction gap between axon of neuron with the dendrite of other neuron is knownas synapse. During impulse transmission a series of events occur at synapse. These events are asfollows:Neurotransmitter synthesis:The electrical signals are not able to cross the gap at synapticjunction (Lenihan, Myers and Tan, 2016). Thus, these signals are converted into chemical1
