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.
Answer:
B. 20%
Explanation:
The complementary base-pairing rule states that Adenine always pairs with Thymine (A with T), and Cytosine with Guanine (C with G).
Because of this, the amount of Adenine present must be the same as the amount of Thymine present, and the same for Cytosine and Guanine.
This means that if there is 30% Adenine, there is also 30% Thymine as each A base is paired to a T base. This adds to 60%, so Cytosine amounts and Guanine amounts must add to 40% to make 100%.
Since they are equal in amount, there must be 20% of each.
Therefore the answer is B. 20%
There is 30% Adenine, 30% Thymine, 20% Guanine and 20% Cytosine.

Lecithin is (organic chemistry) the principal phospholipid in animals; it is particularly abundant in egg yolks, and is extracted commercially from soy. It is also a major constituent of cell membranes, and is commonly used as a food additive (as an emulsifier). While cephalin is (biochemistry) a phospholipid found particularly in the cells of nervous tissue; it is also the primary phospholipid in bacteria.
