Si una población crece mucho otra vez después de un cuello de botella con el paso del tiempo aumentará diversidad genética ¿por
sammy [17]

Answer:

los mecanismos capaces de generar diversidad actúan para incrementar la variabilidad genética en la población que sufrió el cuello de botella

Explanation:

Un cuello de botella se refiere a una reducción drástica en el tamaño de una población (por ejemplo, debido a una catástrofe natural). Un cuello de botella es un fenómeno que está asociado a la ​reducción en la variación genética y fijación de ciertos alelos en la población resultante, lo cual es causado por la deriva genética, es decir, debido al muestreo al azar de los individuos que formarán la población en la siguiente generación. Paulatinamente, los mecanismos capaces de generar variabilidad genética aumentarán nuevamente la diversidad de la población que sufrió el cuello de botella. En una población de reproducción sexual, la variación genética se genera mediante cuatro procesos diferentes: 1-mutación (es decir, la aparición de nuevos alelos debido a alteraciones en la secuencia de ADN); 2-recombinación (es decir, el intercambio de información genética entre cromátidas no hermanas durante la meiosis); 3-segregación independiente de cromosomas durante la meiosis (capaz de producir nuevas combinaciones de alelos) y 4-fertilización al azar (lo cual también incrementa el número de combinaciones entre gametos que darán lugar a un nuevo individuo).

Why do you think scientists want to be able to forecast space weather?
DiKsa [7]

Answer:

Scientists would most likely want to forecast space weather in order to know if it is safe for not only to lift off into outer space, but to be able to help astronauts in any case of emergency if something were to happen in the future.

Such as debris of small rocks that could pass by, so then astronauts would have to stay in the shuttle. To be protected from it.

In any case, scientists want to forecast the weather in outer space in order to protect astronauts, from any incoming dangers.

A student is investigating the affect of different salts on melting points. Four patches of ice of equal size are roped off and
Rasek [7]
The control variable in any experiment is designed in order to apply the same steps of the experiment but with no change happens in the observations.

In this experiment, the student tries to know the effect of solubility of different water-soluble salts (NaCl, CaCl2 and KCO3) on the melting point of the solution. All these salts dissolve in water and give some effect on the melting point except for the sand as the sand doesn't dissolve in water.
