Explanation:
In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.
Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.
Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.
Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.
Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.
- Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
- This leaves a partial negative charge on it.
- The other electron then becomes partially positively charged.
- We can then say, the more electronegative specie undergoes reduction.
- The less electronegative one undergoes oxidation.

Answer:
La razón por la que a partir de los núcleos de las células del intestino de un renacuajo albino, se obtuvieron ranas albinas en lugar de células intenstinales, es que fué un experimento de clonación.
Explanation:
Este experimento realizado por John Gurdon en 1960, se conoce también como transferencia nuclear, y demostró que la información hereditaria guardada en el núcleo celular, es suficiente para generar un nuevo organismo y permanece integra durante el desarrollo de células diferenciadas debido a sus señales citoplásmicas.
