which of the following is a toxic waste that the kidneys excrete? a) water b) ammonia c) calcium d) all of the above
IrinaVladis [17]

Answer: (D) all of the above.

Explanation:

The kidneys remove wastes and <u>extra water</u> from the blood to form urine. Urine flows from the kidneys to the bladder through the ureters.

<u>Ammonia is an extremely toxic base and its accumulation in the body would quickly be fatal.</u> The liver contains a system of carrier molecules and enzymes which quickly converts the ammonia (and carbon dioxide) into urea (waste).

Calcium excretion in the urine is a function of the balance between the calcium load <u>filtered by the kidneys</u> and the efficiency of reabsorption from the renal tubules.

Please help me- how does rock layer h compare to rock layer m?
exis [7]

Answer: Rock layer H is much newer than rock layer M. If all layers were perfectly stacked, the lower layer would be older. However, since we can see Layer H was probably formed by a crack that was filled with magma, Layer H will be newer.
