Rank the sequence of events at the NMJ that initiate an action potential in the muscle fiber, from first to last.
wlad13 [49]

The correct order is:

- Action potential arrives at the axon terminal.

- Calcium ions enter the axon terminal.

- Synaptic vesicles fuse to membrane of axon terminal.

- Acetylcholine is released into the synaptic cleft.

- Acetylcholine binds to its receptors on the junctional folds.

- Junctional folds become depolarized.

- Action potential is initiated on the sarcolemma.

Action potential travels through the membrane of the presynaptic cell causing the channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells. Neurotransmitter binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell).

Characteristics of fruits dispersed by mammals​
tensa zangetsu [6.8K]

Answer:

The stones and pips pass through the animal's digestive system and are excreted to form new plants. This can be far away from the parent plant. Blackberry, cherry and apple seeds are dispersed in this way. Birds also like to eat fruit and they help to disperse seeds to other areas through their droppings.

Explanation:

Hopefully that helps.
