It's the sodium ion.
When a neural impulse is fired in both neurons, it is always cause by an excited electron in one neuron moving to the other neuron to destabilize the balance of ions trying to keep them at equilibrium. This action either depolarizes or hyper-polarizes the membrane. If it does, then sodium ions--the key deficient ones--can flow into that region of low charge and maintain that state of low charge, keeping the cell membrane stable.
Answer:
Cellular membrane.
Explanation:
In prokaryotes electron transport chain isIn prokaryotes electron transport chain is located in the cell membrane. ETC is defined as the series of complexes which helps in the transfer of electrons from electron donors to electron acceptors via reduction, and oxidation reaction couple the transfer of protons with electron transport across a member.
The primary function of the ETC is generated a transmembrane proton electrochemical gradient, such as oxidation, and reduction reaction.
Answer:
What Is the Evidence for Evolution? Darwin used multiple lines of evidence to support his theory of evolution by natural selection -- fossil evidence, biogeographical evidence, and anatomical evidence. Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are likely to be evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. ... In humans, the tail is reduced to the tail bone.
Image result for Three lines of evidence that provide support for common ancestry and evolution are Similar embryology, Molecular homologies, and The Fossil Record.
Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.
