Answer #1

The right answer of the 1st question is .. option b or " b.filtrate...blood "

Tubular reabsorption is highly selective process that retrieves materials from tubular fluid and returns them to the bloodstream . At first the filtration occur by the glomerular capillaries except plasma proteins . The filtered fluid also contains nitrients , ions and other essential sunstances , this essential substances are returned to the blood by the process of tubular reabsortion.

The right answer of the 2nd question is option d

" d. all of the above "

Elemination of the toxin substances is done by kidny. Like the elimination of urea . Also kidney has the reabsorption function to store the essential substances like nutrient and minerals also it reabsorb the water .
