Answer:The correct order is:
Ion channels - synaptic vesicle - neurotransmitter - end plate potential.
Explanation: A neuromuscular junction is the point where a motor neuron meets with a skeletal muscle fiber which it innervates.
It is the site where a chemical interaction or communication between a motor neuron and a muscle cell occurs. For transmission of impulses to occur between a neuron and a muscle cell, an action potential from the motor neuron travels along the axon of the neuron to the presynaptic terminal of the neuron where it activates voltage gated calcium ion channels which causes the influx of calcium ions into the intracellular space of the neuron. The calcium ions bind to the sensor proteins that are located on the synaptic vesicles and trigger the release of the neurotransmitter into the synaptic cleft. The neurotransmitter moves from the synaptic cleft and binds to its receptors on the postsynaptic membrane of the muscle cell. The binding of the neurotransmitter to its receptors creates end plate potential which causes the skeletal muscle fibers to depolarise.

<h3>
What is Organ donation?</h3>
Organ donation is the process by which a person knowingly consents to having one of their own organs legally removed and transplanted into someone else, either while they are still alive or after they have passed away with the consent of their family.
Donations can be made for medical research or, more frequently, for the transplantation of healthy organs and tissues into other people.
The kidneys, heart, liver, pancreas, intestines, lungs, bones, bone marrow, skin, and corneas are among the organs that are frequently transplanted. While some organs and tissues, such as a kidney or a portion of the liver, pancreas, lungs, or intestines, can be donated by living donors, the majority of donations take place after the donor has passed away.

Answer:
Cytoplasm
Explanation:
Cytoplasm is the semi fluid gel like substance of a cell that is present within the cellular membranes and surrounds the nucleus.
It moves around feeding on organic matters like bacteria and other micro particles
Answer:
Choice B
Explanation:
"Permeable" means "Letting solids or liquids through (a material.)" "Semi" means "half or partly." So "semipermeable" means allowing some objects through, but not all.
