Detailed explanation-1: -Answer and Explanation: The statement that is not true about open and closed circulatory systems is D. The open circulatory system of a Monarch butterfly does not transport O2 to body cells, closed circulatory systems do transport O2 to body cells.
Detailed explanation-2: -1. What is false about closed circulatory system? False is that blood pressure is high and regular.
Detailed explanation-3: -A closed circulatory system includes at least one true heart and a network of enclosed blood vessels. It allows either single circulation, in which blood flows through the gills and body in one continuous loop or double circulation with separate pulmonary and systemic blood vessel circuits.
Detailed explanation-4: -In a closed circulatory system, blood is contained inside blood vessels and circulates unidirectionally from the heart around the systemic circulatory route, then returns to the heart again. As opposed to a closed system, arthropods– including insects, crustaceans, and most mollusks– have an ‘open’ circulatory system.
