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

Check out a sample textbook solutionStudents 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)
Describe osmoregulators or osmoconformers and
how these tools allow animals to adapt to
different environments
In your own words:
Elucidate the fundamental challenges the aquatic vertebrates and terrestrial vertebrates face in osmoregulation and their strategies to overcome them. Emphasize the modifications of their osmoregulatory organs.
