Chapter 44.3, Problem 1CC
Summary Introduction
To compare: The ways in which the
Concept introduction: The excretory system varies in the flatworm, earthworms and the insects. The earthworms have metanephridia, protonephridia in flatworms and Malpighian tubules in insects are present for excreting the metabolic wastes.

- The excretory systems of annelids and mollusks include structures called nephridia, while the excretory systems of insects and spiders include Malpighian tubules. Which is a significant difference between nephridia and Malpighian tubules?arrow_forwardDescribe the three steps in which organisms excrete wastes.arrow_forwardBirds that live in marine environments and thus lack access to fresh drinking water A)obtain water by eating only osmoregulating prey. B)osmoregulate without using a transport epithelium for this purpose. C)drink seawater and secrete excess ions through their kidneys only. D)drink seawater and secrete excess ions mainly through their nasal salt glands. E)have plasma that is isoosmotic to ocean water.arrow_forward

One genus lives in a desert environment and the other lives in fresh water. Researchers dissected the snails and measured the amount of uric acid present in the snail nephridia (the typical excretory organ of gastropods). • Using the information from the table below, identify the environment in which each genus of snail lives. Explain your reasoning." • What do you think would be the major nitrogenous waste excreted by Lanistes ? Explain your reasoning. Table 3.

- The 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_forwardContrast the ways fish, mammals, and birds eliminate nitrogenous wastes from their bodies.arrow_forwardMatch the phylum with the excretory system. 1.
