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).
Genetically modified crops are produced through an organism that undergone changes in its DNA using the process of Genetic Engineering. Genetically foods are being generated and tested inside a laboratory. A natural tastes and feature of a food is being change into something different in tastes and feature.
The correct answers are shorter, longer, and have inverse proportionality and are used in dental radiography.
In the first case vertical angulation is what is used to control the length of any image which is being recorded and it is dictated by the holding device which directs the beam of x-ray perpendicular to both the receptor and teeth and in this case the image which is formed is shorter then the real teeth and it also occurs if the central ray is directed perpendicular to the plane of the receptor rather than to the imaginary bisector.
In the second case, the vertical angulation is flat or if it is too small the image of the teeth will be longer than the actual teeth and it often occurs due to bisecting technique.
Distortion is any kind of change that can occur in both the shape and size of the object and this is inversely proportional to the vertical angulation as when vertical angulation is not correct it creates distortion and also the steep is angulation the smaller the image will be and flat the angulation is the larger or longer the image is and in distortion which comes due to radiograph is mainly used for the teeth and the recommended angulation is +10 degree in which the central ray is directed through the contact of the teeth.
This is also called dental radiography.

Vascular plants is the phloem, (vessal) that transports food and the xylem transports water. Nomvascular plants are small with no vascular system. Which means non vascular plants do not have a phloem or a xylem.
