Fill in the missing sections in the following flow chart. (AS1)

Do you think body’s team work maintains the functioning of our body? Justify your answer with an example. (AS1)

Give an example of coordination in your body where both hormonal and nervous control function together. (AS1)

Consider that you are passing by a garbage disposal area and you immediately cover your nose. Arrange the events below in a logical order by marking them from 1 to 5 to trace the events that happen in the nervous system from detection of foul smell (stimulus generation) to covering your nose (response). (AS1)

A. At the end of the axon, electrical impulse releases chemicals

B. Stimulus received by the dendrites of a neuron sets off a chemical reaction that creates an electrical impulse.

C. Electrical impulse transmitted through cell body and axon

D. The chemicals cross the synapse and reach the next neuron. Similarly, the electrical impulse crosses several neurons

E. Finally, the impulse is delivered from neuron to the gland that helps in recognition of the foul smell and muscle cells that help in covering the nose

What is a synapse? How is it useful in transfer information? (AS1)
