Concerning nitrogenous wastes in the human body, what are the different forms, and what are their sources?
In general terms, explain the role in insects of the malpighian tubules and rectum in conserving water, ions, and amino acids and removing nitrogen waste.
Which statement about nitrogenous wastes is true?
ammonia cannot be concentrated as much as urea and uric acid because it is more toxic
some vertebrates are able to avoid producing nitrogenous wastes by using only anaerobic respiration
most vertebrates that produce urea excrete the urea as salt crystals that have precipitated out of solution to conserve water
many saurapsids excrete their nitrogenous wastes as nitric oxide
All of these are correct
