An action potential causes the release of neurotransmitters by:________.
seraphim [82]

Answer:

b) opening calcium pores in the membrane

Explanation:

The opening of calcium  ions channels facilitates the migration of vesicles containing neurotransmitters in the pre-synaptic neurons  to the tip of the post-synaptic membrane. at the <u>neuromuscular  junction </u>These neurotransmitters can either be <u>cholinergic or non-chorlinergic.</u>   <u>At the tip  of the pre-synaptic membranes the vesicles empty their neurotransmitter contents into the synapse.</u>

The neurotransmitters,  diffuse through the neuromuscular junction to bind  with the receptors on the <u>post-synaptic membrane on the post-synaptic neuron.</u> This  stimulates opening of<u> ligand gated sodium ions,</u> and sodium ions  diffuse into the post-synaptic neuronal membrane, to cause <u>depolarization</u>. if the stimulus is  up to the threshold levels   it  generate action potential.

Therefore , more calcium ions channels opening produces; more diffusion of neurotransmitters;leading to opening of more sodium channels for depolarization; and IPSP or EPSP  generation.

When plasma is transfused into a person, why is blood type not a concern?
Dvinal [7]
Blood type is not a concern when transfusing plasma from person to person because the plasma does not contain red blood cells. when things such as organs or blood are given to people (contain red blood cells), they must match the blood type of the person receiving these things so that there is a smaller chance of the person rejecting the organs, blood, etc. due to plasma not having red blood cells, we do not need to worry about the body rejecting it.
let me know if you need help with anything else

7. Imagine that all nations agreed to reduce greenhouse gas emissions by half in an effort to reduce global warming. In what way
larisa86 [58]

If all nations agreed to reduce global warming then It would be good because the seals need icy conditions. So the less global warming then the more icy habitats there will be and the seals will have more places to live.
