Answer:
Binding of <u>ACh (acetylcholine) </u> to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.
Explanation:
It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.
Hence , the answer is <u>ACh (acetylcholine) .</u>
Answer:
So many factors influence the climate. Some of them are ocean currents, latitude, distance from the ocean, elevation, etc.
Explanation:
The distance from the ocean influences the climate of the place. If the place is located on the coast, the climate will be colder and humidity will be higher.
Thanks to ocean currents the temperature can be changed. Ocean currents can low the temperature but also make it very high.
Latitude has an influence also regarding the temperature. Elevation, as it gets higher, the air above is falling, so the pressure decreases.
Regarding all the factors above, we can say that New York has hot summers, with high humidity and very cold winters, full of snow. Close to the river, the ground is muddy and going to the mountains, the ground is getting rocky
Answer:
Ice Age Explanation. Fluctuations in the amount of insolation (incoming solar radiation) are the most likely cause of large-scale changes in Earth's climate during the Quaternary. In other words, variations in the intensity and timing of heat from the sun are the most likely cause of the glacial/interglacial cycles.
