Question
Chapter 36, Problem 1FIB
Summary Introduction
Introduction:
Nitrogenous wastes are the metabolic wastes that contain nitrogen. The organisms tend to excrete harmful wastes out of the body because it contains toxic waste and is not required by the body. In the excretory cycle, these wastes are collected in a certain part of the body then excreted out in the form of urine.

- 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 correctarrow_forwardAs the text noted, two-thirds of the water and solutes that the body reclaims by reabsorption in nephrons occurs in the proximal tubule. Proximal tubule cells have large numbers of mitochondria and demand a great deal of oxygen. Explain why.arrow_forwardJessica was trying to solve a problem given to her in class.

- the process that initiates urine formation in most types of vertebrates is ultrafiltration of fluid from the blood plasma into kidney tubules under the force of blood pressure. What properties of the blood plasma in the urine-forming structures of the kidney are likely to affect the rate of ultrafiltration into the kidney tubules? Why is failure of urine production a potential side effect of heart disease?arrow_forwardA vampire bat survives on mammalian blood.

Predict how the urine of a vampire bat would differ compared to an omnivorous mammal such as you.arrow_forwardThe bodily fluids of freshwater fish contain higher concentration of dissolved solids in their surroundings, so they tend to bloat (take in water) or lose electrolytes. How can freshwater fish avoid this? 1.) By drinking lots of water? 2.) By actively transporting ions out from the gills into the water? 3.) by excreting highly concentrated urine? 4.) by resorbing ions in nephronsarrow_forward
- Which of the following could cause an INCREASE in the concentrations of ions found in the blood? 1. The glomerulus (Bowman's capsule) filters more substances than it's supposed to 2. The nephron reduces the amount of substances allowed to leave 3. More water is reabsorbed in the urinary system than usual 4.
