Answer 1

Answer:

a chemical substance which is released at the end of a nerve fibre by the arrival of a nerve impulse and, by diffusing across the synapse or junction, effects the transfer of the impulse to another nerve fibre, a muscle fibre, or some other structure.

i will solve it

Answer 2

Answer:

x²-y²=(x+y)(x-y)

37=37×1 37 is prime

hence, x+y=37

x-y=1

x=19, y=18

x²+y²=19²+18²=361+324=685
