What did Chargaff discover while studying bases in the DNA of organisms? The bases in the DNA of each organism were unique. The

ratios of thymine and adenine were similar, as were the ratios of guanine and cytosine. The overall percentages of bases were different from one organism to the next. There were equal amounts of all four bases in every organism, or 25 percent of each base.

Answer: The correct answer is - The ratios of Thymine and Adenine were similar, as were the ratios of Guanine and Cytosine.

According to the Chargaff's rule, in a DNA molecule, the amount of Guanine (G) is equal to the amount of Cytosine (C) and the amount of Adenine (A) is equal to the amount of Thymine (T).

This is because A pairs with T and G pairs with C.

This means that the ratio of T and A are similar, as are the ratio of G and C.

What animal filled the role of top predator in yellowstone before wolves were reintroduced?
mixer [17]

Answer:

Explanation:

El Parque Nacional de Yellowstone (Estados Unidos), considerado el parque nacional más antiguo del mundo, fue creado en 1872 durante la presidencia de Ulysses S. Grant. En sus inicios, la fauna del parque no recibió la misma protección que hoy en día: los lobos y los pumas fueron eliminados deliberadamente en 1926 y, al cabo de unos años, la población de ciervos aumentó tanto que los administradores del parque reconocieron que los herbívoros estaban alterando la vegetación, por lo que se realizaron matanzas selectivas para controlar la población de dichos animales. Las matanzas selectivas terminaron a finales de los años 60 y la población de ciervos volvió a aumentar, por lo que finalmente se optó por reintroducir el lobo: 14 lobos de la provincia de Alberta (Canadá) fueron liberados en 1995 y otros 17 lobos canadienses en 1996. "La reintroducción del lobo (Canis lupus) en el Parque Nacional de Yellowstone es el experimento ecológico más celebrado de la historia", así comienza un estudio publicado en Journal of Mammalogy por Mark Boyce, de la Universidad de Alberta.

If an atom has a mass number of 23, which of the following is always true? A. The number of protons in the nucleus does not equa
Westkost [7]
The correct answer will be A;

A) The number of protons in the nucleus does not equal the number of neutrons.

A=mass number:
Z=atomic number (= number of protons)
N=number of neutrons:

A=Z+N

If the number of protons in the nucleus is equal the number of neutrons , we would have an even mass number; because Z=N=x; then A=x+x=2x  (this is always an even number) but  23 is an odd number, therefore the number of protons in the nucleus does not equal the number of neutrons.
