4 0

Answer:

Cells from the cheek are a type of epithelial cell, similar to skin. ... They can be seen faintly even at 40x (scanning power), but the most dramatic images are at 400x where the nucleus is clearly visible as a dark spot in the center of the cell.

Which cells are considered excitable cells because they are able to produce electrical signals?
jek_recluse [69]
<span>These are excitable and action potential cells, because when they receive a stimulus they activate an action potential, these stimuli are electrical, chemical, mechanical and photonic. The action potential changes rapidly in the membrane potential in response to a stimulus and returns a resting potential. The action potential has several stages, and its main characteristics are that nothing is produced or produced when generated is maintained and propagated, the time of the voltage-dependent channels remain open. The types of the action potential are spike potential, plateau potential, potential and rhythmic potentials.</span>

Redox reactions refer to a pair of reactions in which a particular oxidation is coupled to a corresponding reduction. Although n
Bad White [126]

Answer:

The Equations sort each listed half reaction as either an oxidation or a reduction.

Fe + CuSO4 + → FeSO4 + Cu

(Fe oxidized, Cu reduced)

Explanation:

For proper understanding of the concept of the Redox reaction, let us know the meaning:

Reduction- Oxidation or "redox" reactions occur when elements in a chemical reaction gain or lose electrons. This reaction causes an increase or decrease in oxidation numbers. The Half Equation Method is used to balance these reactions. The equation is separated into two half-equations, one for oxidation and one for reduction. For Example -

CuO + H2 → Cu +H2O.

In this redox reaction, CuO is getting reduced to Cu since Oxygen is getting removed.

Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s) Oxidation state of Fe changes from 0 to +2 and oxidation state of Cu changes from +2 to 0.
