Lee la siguiente situación, y diseña un experimento. (No tienes que realizarlo)
Lynna [10]

Answer:

- Luis quiere saber si los cristales de yodo pueden disuelverse en distintos líquidos  

- Luis necesita cristales de yodo, agua, alcohol y aceite mineral

- La hipótesis de trabajo puede ser: "los cristales de yodo se disuelven en distintos líquidos", con lo cual la hipótesis alternativa indicaría que los cristales de iodo no se disuelven

- La recopilación de los datos puede consistir en la realización de tres experimentos en los cuales los cristales de yodo son sumergidos en agua (1° experimento), alcohol (2° experimento) y aceite (3° experimento).  

Explanation:

En el método científico, la pregunta científica refiere a una cuestión particular la cual es planteada con el objetivo de responder algún aspecto particular del mundo real. A partir del planteamiento de una pregunta científica es posible formular dos hipotésis denominadas hipotésis nula e hipótesis alternativa, las cuales representan supocisiones contrapuestas que permiten contestar dicha cuestión. Subsecuentemente, los científicos realizan experimentos y/o observaciones que permiten recopilar datos cuyos resultados son utilizados para confirmar (o rechazar) la hipótesis nula. Por otra parte, es necesario resaltar que durante el proceso de experimentación se requiere de la utilización de controles positivos y negativos que permitirán corroborar si dichos experimentos fueron realizados correctamente.

What did the Watson-Crick model suggest about the replication of DNA?
Setler [38]

Answer:

c. If the double helix were unwound, each nucleotide along the two parent strands would form a hydrogen bond with its complementary nucleotide.

Explanation:

According to the Watson-Crick model, two DNA strands are held together by complementary base pairing wherein each nucleotide of one DNA strand forms hydrogen bonds with its complementary nucleotide present in the other strand. During DNA replication, two DNA strands are separated by the action of helicases enzymes.

The separated DNA strands serve as a template for DNA replication. Here, each nucleotide of the template DNA strand binds to its complementary nucleotide by hydrogen bonds. For example, adenine of the template strand forms two hydrogen bonds with thymine while guanine forms three hydrogen bonds with cytosine.
