clear vision
Explanation:
maybe because if it swims at night it needs good eyesight to see
1.3x - 2 - (3.3x + 5) = 2x + 1
1.3x - 2 - 3.3x - 5 = 2x + 1
-2x - 7 = 2x + 1
-7 = 4x + 1
-8 = 4x
x = -2
travels along an axon. this triggers a wave of electrical activity that passes from the cell body along the length of the axon to the synapse
