Sharks are osmoconformers, however, they are not strict osmoconformers because of which of the following reasons?Multiple choice question.The osmolarity of their blood changes at night.The concentration of NaCl in their blood is higher than that of seawater.All the NaCl in their blood is replaced with KCl.The concentration of NaCl in their blood is lower than that of seawater.

Which of the following is an osmoconformer?a) Freshwater fishb) Sea anemonec) Marine bony fishd) An anadromous fish

Question 6SavedContinuing from the previous question, compare shark lamellas and alveoli in humans.

What type of osmoregulatory adaptations are usually present in marine vertebrates?Multiple choice question.Adaptations that make them more permeable to waterAdaptations that prevent water from entering their bodiesAdaptations that prevent them from drinking seawaterAdaptations that prevent dehydration

Sharks belong to which class of Vertebrata?Group of answer choicesActinopterygiiAgnathaOsteichthyesChondrichthyes

How are marine and freshwater osmoregulators similar or different with respect to their tonicity relative to their environment?Multiple choice question.They are similar because they are both isotonic to their respective environments.They differ because marine ones are hyper-, while freshwater ones are isotonic.They differ because marine ones are hypo-, while freshwater ones are hypertonic.They differ because marine ones are hyper-, while freshwater ones are hypotonic.
