Los desechos nitrogenados son los productos de la degradación de los aminoácidos y las bases nitrogenadas. Por ejemplo, el amoniaco es el principal producto de excreción de invertebrados acuáticos y algunos peces óseos; se trata de una sustancia altamente tóxica pero, por ser soluble en agua, se diluye con rapidez. La urea es el principal producto de desecho de anfibios, peces cartilaginosos y muchos mamíferos. Se produce en el hígado mediante la transformación del amoniaco. Esta es menos tóxica y más soluble y, por ende, puede liberarse en concentraciones mayores. ¿Existe alguna relación entre el ambiente en el que se desarrollan los organismos y el tipo de desecho nitrogenado que producen? Seleccione una:
a. Sí, algunos desechos nitrogenados pueden ser eliminados con mayor facilidad en ciertos ambientes y en otros no.
b. Sí, porque no todos los desechos nitrogenados tienen los mismos niveles de toxicidad.
c. No, simplemente los organismos acumulan los desechos para su defensa.
d. No, los desechos nitrogenados se producen de acuerdo con el tipo de dieta que tenga el organismo.

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:
