SYNTHESIZE YOUR KNOWLEDGE
The marine iguana (Amblyrhynchus cristatus), which spends long periods under water feeding on seaweed, relies on both salt glands and kidneys for homeostasis of its internal fluids. Describe how these organs together meet the particular osmoregulatory challenges of this animal’s environment.

Students have asked these similar questions
Which mechanism of osmoregulation is shared by sharks and hagfish?
the osmolarity of their plasma is about the same as that of sea water
both are osmoregulators
both excrete all of their nitrogenous wastes as uric acid
both drink large amounts of fresh water to avoid desiccation (drying out)
The mammalian kidney contains an immense network of nephrons that functions to conserve water by producing urine that is hyperosmotic compared to other body fluids.
Describe in detail how the transport epithelia of the nephron and collecting duct are able to use transport mechanisms to process the filtrate as it moves through the vessels and produce a hyperosmotic filtrate.
In the aquatic world, osmoregulation is very important. Please describe what would happen at the cellular level as well as organismal level to a freshwater fish that is placed in salt water.

- All osmoregulators are marine. This statement is (T/F). • If true, enter x in the blanks below. • If false, then how would you change the sentence to make it correct? You can change two words at most. Changes that just reverse the meaning (e.g. changing "is" to "isn't" or "all" to "none") will not earn credit. I would change the word(s) to the word(s) to make the sentence correct.arrow_forwardDescribe osmoregulators or osmoconformers and how these tools allow animals to adapt to different environmentsarrow_forward10) Osmoregulation refers to the ability of an organism to maintain homeostasis with respect to the solute concentration of their bodies. Euryhaline fish are able to live in both fresh water and salt water at different points of their life. In order to osmoregulate in both environments, one physiological change that occurs in these fish is the direction in which they actively transport ions across their gills. a) In what direction are ions actively transported across the gills of euryhaline fish when they are in freshwater versus salt water? In freshwater: (into body or out of body) In salt water: (into body or out of body) b) Briefly explain why active transport is required in these cases. 121 11) The table below compares and contrasts carrier protein pumps with clathrin-dependent receptor-mediated endocytosis.
