Which of the following is a function of the lymphatic system? Check all that apply 1) Recover fluid from the interstium to the b
nikitadnepr [17]

1 & 2

The lymph system acts like blood vessels only that instead of blood, they carry lymph. Just like certain organs as associated with the circulatory system like heart, the lymph system has such organs like the spleen and thymus.

Explanation:

When blood passes through capillaries, the blood pressure causes the blood plasma to filter through the capillary walls. This fluid then gets into the extracellular spaces of the cells and tissues and nourishes the cells. This fluid in which the cells ‘bath’ in is called interstitial fluid.  Excess interstitial fluid flows back through the lymphatic systems and back to the blood through the subclavian veins of the thoracic duct.

The lymph system has several functions. It is responsible for the removal of foreign material like bacteria because the lymph nodes have 'meshwork' that ‘sieves’ the lymph fluid and immune cells destroy bacteria and viruses.

En el hombre el color negro de los ojos “A” domina sobre el color azul “a” Una pareja en la que el hombre tiene los ojos negros
umka21 [38]

Las respuestas a estas preguntas son:

a) Genotipo del padre Aa (ojos negros)

b) Cruzamiento: Aa (padre) x aa (madre)

c) Frecuencias genotípicas esperadas: 1/2 Aa; 1/2 aa  

En genética, dominancia completa se refiere al proceso  de herencia en la cual un individuo heterocigota, es decir, el individuo que presenta dos alelos diferentes para el mismo gen, presenta el mismo fenotipo que un individuo homo-cigota para el alelo dominante (el alelo dominante es aquel que enmascara la expresión del alelo recesivo en individuos heterocigotas).

En este caso, el carácter 'color de ojos' presenta un patrón de herencia monogénica, donde el alelo 'A' dominante codifica para el rasgo fenotípico ojos negros, mientras que el alelo 'a' recesivo codifica para el rasgo fenotípico ojos azules.  

En el ejemplo, la pareja tuvo progenie en la cual uno de los hijos presenta el rasgo recesivo ojos claros, con lo cual el padre debe ser heterocigota y poseer un alelo recesivo 'a'; mientras que la madre expresa el fenotipo recesivo y por lo tanto su genotipo es 'aa'. En consecuencia, el cruzamiento de un padre heterozigota 'Aa' con una madre homo-cigota recesivo 'aa' producirá una descendencia con una frecuencia genotípica esperada de 1/2 (50%) de hijos con ojos 'color negro' de genotipo Aa y 1/2 (50%) de hijos con ojos 'color celelste' de genotipo aa >>

Cruzamiento: Aa (padre) x aa (madre)

Gametos padre: 1/2 A; 1/2 a

Gametos madre: 100% a

Cuadro de Punett (combinaciones gaméticas):

                  A           a

a               Aa          aa

a               Aa          aa

En consecuencia,  este cruzamiento producirá 50% individuos ojos color negro (genotipo Aa) y 50% individuos con ojos color celelste (genotipo aa)
