Smaller size = Large total surface area to volume ratio, True, False, A thin respiratory structure that is one cell thick, allows the diffusion of respiratory gases to occur., True, False, The surface of the respiratory structure is always dry for respiratory gases to dissolve in them., True , False, Some insect have air sacs to speed up the delivery of respiratory gas during active body movements., True, False, The lamella membrane is thin and supplied with less blood capillaries for easy absorption., True, False, Frog use skin during active state., True, False, The respiratory structure of fish is , Moist Alveolus, Thin filament and lamallae, Numerous Tracheole, Skin and lungs, The respiratory structure of human is, Moist Alveolus, Thin filament and lamallae, Numerous Tracheole, Skin and lungs, Numerous Alveolus is important for, Increase total surface area to volume ratio, Decrease total surface area to volume ratio, Less efficient of oxygen diffusion, Less efficient of Carbon dioxide diffusion, Why specific respiratory structures are suitable for their habitats?, because they are adapted to obtain oxygen efficiently from the surrounding environment (air or water) and remove carbon dioxide., because they are adapted to obtain Carbon dioxide efficiently from the surrounding environment (air or water) and remove oxygen.., because they are adapted to obtain nutrient efficiently from the surrounding environment, All above, Which one is the adaptations of skin of frogs that allow efficient gaseous exchange?, Dry skin allow dissolvesthe gases diffuse, Less blood capillaries for gases transport., Beneath the skin, many network of blood capillaries., Thick skin and not permeable .
