Answer:

The correct answer is: (B) erythropoietin (EPO) – increases white blood cell production.

Explanation:

Erythropoietin is a hormone secreted by the kidney when dealing to cellular hypoxia (low oxygen content on body tissues) to stimulate red blood cell production. This is because red blood cells are the ones that transport oxygen to every tissue in the body.

liq [111]

Answer:

Variable expressivity, Incomplete penetrance, Phenocopy, Genetic heterogeneity

Explanation:

Phenocopy: When an environmentally caused phenotype mimics one that has a genetic basis. The variation in phenotype caused by environmental conditions exists in such a way that the organism's phenotype matches a phenotype which is determined by genetic factors.

Variable expressivity: When a characteristic is subject to a range in severity or degree of expression in the phenotype.

Genetic heterogeneity: When the same phenotype/disease can be caused by different genes.

Incomplete penetrance: When individuals have a genotype that specifies a particular phenotype but that phenotype does not develop.

Naily [24]

Answer:

Caso de estudio: El efecto de estresores ambientales sobre el comportamiento animal

- Ejemplo de un tipo de estudio cualitativo: la influencia de estresores ambientales (por ej. niveles anormales de dióxido de carbono atmosférico) sobre el comportamiento en ratones de laboratorio  

- Ejemplo de un tipo de estudio cuantitativo: la influencia de estresores ambientales sobre los niveles de producción de hormonas asociadas a cambios comportamentales en ratones de laboratorio  

Explanation:

Un enfoque cualitativo se caracteriza por el hecho de que la información obtenida durante dicho estudio se agrupa en categorías mutuamente excluyentes. En biología, los estudios de tipo cualitativo generalmente se caen dentro de la dicotomía observacional (es decir, presencia o ausencia del factor en estudio). En el ejemplo arriba citado, es posible obtener datos relacionados a uno o más determinado aspectos comportamentales en los individuos bajo estudio (por ejemplo, presencia o ausencia de signos de irritabilidad) en ratones sometidos a algún estresor ambiental (por ejemplo, niveles anormales de CO2 atmosférico). Por otra parte, en un enfoque cuantitativo, la información se recopila en intervalos obtenidos a partir de operaciones aritméticas (estadística paramétrica). En el ejemplo, los datos obtenidos pueden ser clasificados en intervalos referidos a los niveles hormonales. Esta información resulta útil para determinar si las diferencias en los niveles hormonales entre individuos que se encuentran en presencia del estresor ambiental son estadísticamente significativas respecto al grupo control (individuos desarrollados en un ambiente con niveles normales de CO2 atmosférico), y de este modo concluir si el estresor ambiental puede o no modificar variables comportamentales. Los estudios cualitativos permiten el uso de variables independientes las cuales son clasificadas como cualitativas (discretas).
