a) true
b) false.
the influx of calcium ions at the synaptic terminal causes the fusion of synaptic vesicles with the terminal membrane and results in the release of neurotransmitters that bind to postsynaptic ion channels.

Answer (True)Axon of first neuron to dendrites, cell body, and axon of second neuron

(True)The influx of calcium ions at the synaptic terminal causes the fusion of synaptic vesicles with the terminal membrane and results in the release of neurotransmitters that bind to postsynaptic ion channels.

Explanation:

The first answer explains the transmission pathway of action potential in a neuron with ELECTRICAL SYNAPSE at dendrites.

This is an exemple of SULTATORY CONDUCTION,because the action potential jumps from one Nodes of Ranvier to another along the axon.

The second answer explains transmission from pre-synaptic neuron ,with CHEMICAL SYNAPSE initiated by calcium ion in influx into the synaptic cleft at terminal ends; for transmission of action potential to the post synaptic neuron to induce inhibition or excitation of muscles.

The neurotransmitters released binds with the receptors on the post synaptic neuron to ensure crossing /transmission of action potential

uh two lol

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
