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>
It's also known as ulnar drift.

Answer:
Image result for Explain the technology watney used in the first chapter of the martian
The Mars Ascent Vehicle in "The Martian" is powered by a radioisotope thermoelectric generator (RTG), which converts the heat of the radioactive decay of plutonium-238 into electricity. This RTG is buried a safe distance away from the pioneers' living quarters.
Explanation:
In plant cells, chloroplasts convert light energy into chemical energy, and mitochondria consume the chemical energy to produce ATP.
