Which of the following pairs are correctly matched? (1) Poikilo-osmotic ?Animals show osmotic dependence with respect to the environment (2) Homio-osmodc?Animals maintain body fluid concentrations constant irrespective (of fluctuation in the environmental concentrations (3) Euryhaline?Animals with stand aquatic media of a wide range of concentrations (4) Stenohaline ?Animals survive within a wide range of salinitiesA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: A
Solution :
Poikilosmotic : Organisms having an internal osmotic pressure which varies following closely that of environment, eg, Myxividae. Homiosmotic : Organisms which maintains body fluids at constant osmotic pressure despite changes in the environment. Euryhaline : Organisms capable of withstanding wide range of salinity. Stenohaline : Organisms able to withstand only small changes or ranges in salinity.You need to login to perform this action.
