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.

Where would you most likely find transform boundaries on an earthquake distribution map?
lana66690 [7]

Answer:

1st One

Explanation:

The distribution of earthquakes across the globe is shown in Figure 11.7. It is relatively easy to see the relationships between earthquakes and the plate boundaries. Along divergent boundaries like the mid-Atlantic ridge and the East Pacific Rise, earthquakes are common, but restricted to a narrow zone close to the ridge, and consistently at less than 30 km depth. Shallow earthquakes are also common along transform faults, such as the San Andreas Fault. Along subduction zones, as we saw in Chapter 10, earthquakes are very abundant, and they are increasingly deep on the landward side of the subduction zone
