Answer:
Autotroph or producers
Explanation:
An organism that produces its own food is a autotroph
T<span>he cell requires oxygen, and eukaryotic cells are expensive to run. they require a lot of energy and nutrients, and oxygen is one such component. the oxygen is necessary for aerobic respiration, which allows the cell to do a lot, including evolve, proliferate, adopt new niches, habitats, biochemical habitats, sustain life in extreme conditions, and perhaps eventually co-operate with other cells and create multicellular life. Multicellular life is virtually impossible without aerobic respiration. </span>
Answer:
The influx of calcium ions.
Explanation:
The influx of calcium ions at a certain point produces phase of the action potential also called depolarization which results in the ion movement changes the membrane potential from negative to positive inside the cell.
In action potential, calcium ions may control gene transcription, cell excitability, and neurotransmitter release. In chemical synapses, the influx of calcium ions leads to vesicles filled with neurotransmitters move to the surface of the cell, and into the synaptic cleft release their contents.
the models of the solar system were the couple of planets and a very big star. AKA the sun
