A key understanding of how synapses work is that they must be able to 1. Turn a signal on, 2. Turn a signal off again. Explain why two neurons, one dopaminergic, one glutergic demonstrate this principle in Cocaine addition. In Nicotine addiction, the pathway is reversed, a Cholinergic neuron is followed by a Dopaminergic neuron. The same logic applies. Explain.
I am an addict. Which is my best excuse? 'It’s my genes'. 'It’s my mates'. 'It’s down-regulation of my receptors'. The excuse must be accompanied by an explanation.

a. the amount of water in the plant cell would not
change.
b. the plant cells would gain water .
c. the plant cells would lose water.
d. osmosis will cause water to flow from the hypertonic plant cell
to the hypotonic solution surrounding the cells.
e. osmosis would change the plant cells such as the plant is now
adapted for a salt water environment.
