Question
Chapter 33, Problem 3MCQ
Summary Introduction
Introduction:
The mechanism through which the concentration of ions in the body fluids is regulated is known as osmoregulation. The essential minerals, water, and ions are regulated by the mechanism and the mechanism is different in animals of different habitat.
