Upload your image (may be hand drawn or digitally rendered).In spiders, gas exchange is supplied by (mark all that apply) book lungs book gills Malpighian tubules epidermis tracheae spiracles green glands Home DepotNeither cnidarians nor turbellarians possess a circulatory system. For most large, active animals, this would pose a (fatal) problem. Describe and discuss the features of large active cnidarians ands turbellarians that allow them to respire, nourish their cells, and excrete despite the absence of a conventional circulatory system.

QUESTION 6 Mammalian lungs are very different in structure compared to amphibian lungs. The lungs of mammals have highly complex branching patterns of airways. The lungs of amphibians are simpler and more sac-like. Over all, the lungs of mammals are capable of much greater rates of gas exchange compared to amphibians. Why is this? O The more complex structure provides more surface area across which gas exchange can occur. O A complex structure means that gases have more contact time with gases compared to a simpler structure. O Mammalian lungs are usually much bigger relative to their bodies compared to amphibian lungs. O The respiratory membranes of mammals are able to diffuse gases across them much faster than amphibians. QUESTION 7 Click Save and Submit to save and submit.

- If the frontal cilia of an ascidian pharynx were immobilized what would be the likely consequence(s) closure of siphons no mucus net spreading cessation of gas exchange cessation of the feeding currentIf water passed over the gills of fish in the same direction as blood flow through the capillaries, how would gas exchange be affected? Select all correct choices. More oxygen would diffuse from the water into the fish's bloodstream. Less oxygen would diffuse from the water into the fish's bloodstream. More carbon dioxide would diffuse out of the fish's bloodstream into the water. Less carbon dioxide would diffuse out of the fish's bloodstream into the water. Gas exchange would remain the same, regardless of the direction of water flow.You receive animal care and use committee approval to catch a fish, prop open its operculum (gill cover), tie a string around its tail, and tow it backwards through the water for experimental purposes. The fish is then released unharmed. This action forces water to flow backwards over the gill filaments and in between the gill lamellae. What effect would this backwards water flow have on respiration? It would reduce efficiency of gas exchange between water and blood The only effect would be due to the fish's discomfort from this treatment. O It would improve efficiency of gas exchange between water and blood
