The quantity you are looking for is pH


pH stands for power of hydrogen.

If the pH of a substance is less than 7, the substance is acidic, if the pH of a substance is greater than 7, the substance is basic. If the pH of a substance is 7, it is neutral (water)

Suppose the North American plate is moving away from the Eurasian plate at a rate of 2 cm per year. The eastern-most point of No
Archy [21]

The correct answer is - 1,180 km.

North America and Europe move away from one another, though the two plates, the North American and Eurasian are merging together on the other side. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.

To get to the result we only need to multiply the number of years with the annual movement

2 x 200,000 = 400,000

Than divide the result with 100,000, as that is how much cm are in one km

400,000 / 100,000 = 4

And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.

¿Cómo defines a una Célula Haploide?
Goryan [66]

Answer:

La mitad de cromosomas.

Explicación:

Las células haploides se refieren a aquellas células que tienen la mitad de cromosomas. Estas células haploides se forman debido a la división celular de la meiosis. En la división celular de la meiosis, una célula madre se divide en cuatro células hijas que tienen la mitad de cromosomas. Estas células haploides están presentes en los espermatozoides de los gametos masculinos y femeninos, que se fusionaron formando células diploides que tienen el doble de cromosomas. El cigoto formado debido a la fusión de espermatozoides y óvulos son de naturaleza diploide.
