Triggering of the muscle action potential occurs after Ach binds to chemically gated channels in the motor end plate membrane. Acetylcholine (Ach) is a neurotransmitter produced by nerve cells.
An action potential is an electrical signal that travels along the cell membrane as a wave.
This action potential (muscle action potential) drives the contraction of muscle fibers.
When the action potential reaches the neuromuscular junction (i.e., the motor end-plate), acetylcholine (Ach) is released into the synaptic cleft.
Subsequently, Ach can bind and open specific channels localized on the surface of the muscle cells, thereby depolarizing them and triggering muscle contraction.

Answer:
The correct option is;
True
Explanation:
The digestive system of Cnidarians is incomplete having only one single opening which is the gastrovascular cavity the representing the anus and the mouthof the Cnidarians
The hollow body of the Cnidarian polyp which allows water through has tentacles at the top bearing cells meant for stinging
A prey caught by the tentacles is drawn in to the mouth and ingested
The Cnidarians are able to attach to surface due to their attachment adapted lower end
The correct option is therefore true.
I believe the answer you were looking for is incineration.
Low levels of the neurotransmitter serotonin may appear to contribute to aggression. Dopamine and serotonin are the most hormones that are linked with aggression, that is low level of serotonin and high levels of dopamine. The normal effect of serotonin is the inhibitory effect on aggression levels when at normal levels. At the pre-Frontal Cortex serotonin is usually found at its lowest levelsnand increases aggression.
