Answer:
Faults are the result of the stress caused by tectonic plates. The movement of said plates creates breakage and these breaks are identified as fault lines. When the tectonic plates move and collide along these fault lines earthquakes are caused.

4. Vesicles full of acetylcholine are stored at the axon terminal.
3. Action potential arrives at the neuromuscular junction.
1. Action potential is propagated in the sarcolemma.
5. Acetylcholine is released into the synaptic cleft.
2. Acetylcholine binds to ligand gated sodium channels.
Explanation:
Nerve impulse is generated from somatic motor neurons and reaches neuromuscular junction. The nerve impulse specifically reaches a region named 'synaptic end bulbs' at axon terminal. These synaptic end bulbs are in turn connected to the motor end plate region of a sarcolemma.
As soon as the nerve impulse reaches neuromuscular junction, it triggers the opening of voltage gated ion channels which in turn facilitate the influx of Ca²⁺ from the extracellular fluid to the inside of neuron where synaptic vesicles containing neurotransmitter acetylcholine are already stored.
The Ca²⁺ causes the exocytosis of synaptic vesicles which fuse with the plasma membrane of motor neuron as a result of which acetylcholine is released in the synaptic cleft.
The acetylcholine further binds with the acetylcholine receptor which is present at the motor end plate of a skeletal muscle fibre. These receptors are ligand gated ion channels.
Binding of acetylcholine with its receptor causes the ion channels to open and cations like Na⁺ enter the muscle fibre so as to make the electric potential inside the muscle positive.
A white rose cannot be produced in the G1 (first generation) of roses because the red rose will have a RR (R standing for red) allele combination. The pink rose will have a RW (R for red, W for white) <span>allele combination. When crossed all combinations will have at least one R allele, meaning that no roses (in the first generation) will have a WW allele combination. WW is the only allele combination that produces white roses.

The epithelium is a type of body tissue that forms the covering on all internal and external surfaces of your body.
<h3>
The lining of the air sacs in the lungs (alveoli) is comprised of what epithelium?</h3>
Simple squamous epithelium contain the air sacs or alveoli of the lungs. This kind of squamous epithelial cells are slightly porous which allows the oxygen from the air to enter the blood in the capillaries of the lung. So the squamous epithelium is the epithelium in which the lining of the air sacs or alveoli occurs. Each alveolus is lined by the squamous epithelium.
So we can conclude that: The epithelium is a type of body tissue that forms the covering on all internal and external surfaces of your body.
