Answer:
Generation of an action potential in the neuron.
Stimulation of Ca2+ entry into the neuron
Release of acetylcholine into the synapse
Depolarization of the muscle fiber membrane
Explanation:
The following events takes place in the vertebrate neuromuscular junction
a) Nerve Action Potential - Action potential reaches the axon terminal
b) Entry of calcium ion - The calcium ion reaches the axon terminal and enter into the presynaptic terminus after which the Synaptic vesicles fuse with the membrane of axon terminal
c) Releasing of Arch Quanta - Acetylcholine is released into synaptic cleft which then binds to the receptor sites on motor end plate
d) The Na+/K+ channels opens and Motor end plate becomes depolarized.
Answer: all eukaryotes
Explanation: Plants and animals both preform cellular respiration. Cellular respiration is the process of sugar (glucose) being in the process of transforming into energy for the cells!
Process of using the energy in sunlight to make food (glucose).plastids: A group of closely related membrane-bound plant cell organelles; include schloroplasts<span>, </span>chromoplasts<span> and leucoplasts. stroma: Space outside the </span>thylakoid membranes<span> of a </span>chloroplast<span>; site of the Calvin cycle of photosynthesis.</span>
Answer:
The correct answer will be option-B
Explanation:
The process of transcription transcribes the sequence of the bases of genes present on DNA to mRNA which acts as a messenger molecule for the protein synthesis.
The process of transcription is mediated by the presence of enzymes which includes the main transcription enzyme called RNA polymerase. RNA polymerase attaches nucleotides to RNA strand.
The transcription process initiates in three stages: initiation, elongation and termination.
The initiation process begins when RNA polymerase binds to the promoter nucleotide sequence which is present at the start site or the upstream on DNA towards 5' end.
Thus, Option-B is the correct answer.
Answer:
The process of DNA replication allows for information to be retained that same way as a Flash drive does files. It copies them, and downloads them somewhere else, while keeping them on the drive until terminated. I don't know if this answered your question the way you wanted, but this is how my teacher expalined it in like the 5th grade
