Chapter 48, Problem 16TYU
Test Your Understanding
16 EVOLUTION LINK The kangaroo rat’s diet consists of dry seeds, and it drinks no water. What types of osmoregulatory adaptations might help this animal survive?
Expert Solution & Answer

Students have asked these similar questions
Describe osmoregulators or osmoconformers and
how these tools allow animals to adapt to
different environments
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)
If osmoregulatory hypotonic fish species are generally bony fish and osmoregulatory hypertonic fish species are generally soft and absorbent. Does it mean the reason for them being soft or bony from an evolutionary standpoint gives reason to why they are formed that way?
Basically what I'm trying to ask is whether they are hypotonic or hypertonic, does it have a correlation to why they are bony or muscular like in structure.

Thus: O a. They have high levels of sodium chloride in their cells compared with a bony fish. O b. They produce very little urine. Oc. They have high levels of urea in their blood. O d. Osmoregulation requires a greater expenditure in energy compared with a bony fish. O e. They need much larger salt glands than in a bony fish.arrow_forwardSharks live in marine (saltwater) habitats and are osmoconformers. Based on this information which of the following is/are true (select all that apply): A. Sharks have tissues/body fluids that are isoosmotic relative to the environment B. Sharks have tissues/body fluids that are hypoosmotic relative to the environment C. Sharks devote considerable energy to osmoregulation D.
