Oxygen

Fossil fuels developed from dead (plant and animal) biomass that was converted into what they are today by being exposed to high pressure and heat in the absence of oxygen over the course of millions of years. The main fossil fuels are coal, natural gas and crude oil.

Davy made a model of the water cycle by adding some water inside a plastic bag, sealing the bag, and placing it in a sunny area.
Ad libitum [116K]

<em>Davy made a model of the water cycle by adding some water inside a plastic bag, sealing the bag, and placing it in a sunny area. He noticed that the level of the water went down, and then some droplets appeared on the sides of the bag. which part of the water cycle caused water droplets to form on the side of the plastic bag?  </em>

<em>(a) condensation (b) evaporation (c) precipitation runoff</em>

The part of the water cycle that caused water droplets to form on the side of the plastic bag would be condensation.

<h3>What is condensation?</h3>

It is a process whereby water vapor in the atmosphere condenses or turns back into liquid.

Condensation is as opposed to evaporation. The latter is a process whereby liquid water turns into vapor water. In other words, evaporation and condensation are words and opposites.

Both processes play a major role in the water cycle of the ecosystem.

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).
