Vedclass · Answer

(D) The heart of a frog is myogenic,meaning the heartbeat originates from within the heart muscle itself,specifically from the pacemaker cells (sinus venosus). Because it is myogenic,the heart can continue to beat even after being removed from the body,provided it is supplied with appropriate nutrients and kept in a moist environment to prevent desiccation. If kept dry,the cells will quickly lose their ionic balance and die,causing the heart to stop beating. Therefore,the correct observation is that it will continue to beat for a long time if kept moist.
