. Si el átomo contiene electrones que son partículas con carga eléctrica negativa, ¿por qué el átomo no tiene carga
eléctrica neta?
A. Porque la carga de los electrones de un átomo se equilibra con la de los electrones de los átomos vecinos.
B. Porque los neutrones en el núcleo neutralizan cualquier carga eléctrica.
C. Porque en el átomo existe el mismo número de protones con carga positiva y electrones con carga negativa.
D. Porque los neutrones tienen carga eléctrica positiva que equilibra la carga de los electrones.

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i. e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).
