The epithelial cells in the skin of an animal have 24 chromosomes. How many chromosomes are present in the gametes of this anima
mrs_skeptik [129]

Answer:

There will be 12 chromosomes

Explanation:

We have given that The epithelial cells in the skin of an animal have 24 chromosomes

We have to find the number of chromosomes present in the gametes of this animal

We know that number of chromosomes present in the gametes is given by

\frac{number\ of\ chromosmes\ present\ in\ skin}{2}

So number of chromosomes in gametes =\frac{24}{2}=12chromosomes

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).

If the function of blood vessel is to keep blood flowing in one direction, what would be some things it would need structurally?
Novay_Z [31]

Answer:

Capillaries, the littlest and generally various of the veins, structure the association between the vessels that divert blood from the heart (supply routes) and the vessels that return blood to the heart (veins).

Explanation:

Capillaries, the littlest and generally various of the veins, structure the association between the vessels that divert blood from the heart (supply routes) and the vessels that return blood to the heart (veins). The essential capacity of capillaries is the trading of materials between the blood and tissue cells.  

Blood vessels a cylindrical organization all through the body that permits blood to spill out of the heart to each body cell and afterward back to the heart. The three kinds of veins are corridors, vessels, and veins. Each vein comprises of a layered divider encompassing a focal blood-containing space, or lumen.
