- The function of pharyngeal gills includes: ( can be more than one anwser) a. gas exchange b. generating a feeding current c. eliminating excess water during feeding d. producing a mucous netHow do most insects respire? A. through skinB. through gillsC. by lungsD. by trachea systemIf you got rid of the endostyle of an ascidian, what is most likely to occur? A. no gas exchangeB. it would starveC. mucous net wouldn't be spread across gill slits

- According to the Fick equation, the fish gill is an effective gas exchange surface because... A. It has a high blood-to-water diffusion distance B. The total surface area of the lamellae is very large C. The scaphognathite maintains a constant flow of water across the gill D. The gill tissue is supported by the surrounding water E. All of the aboveYou are confronted with two worms that, on first glance, appear to be very similar. Upon closer examination, however, you note one difference that allows you to identify one specimen as an earthworm and the other as a roundworm. That key characteristic is: A. The presence of a gastrovascular cavity B. The presence of a body cavity C. The presence of a muscle layer around the digestive tract D. The absence of a specialized gas exchange surface E. None of the characteristics listed above would allow an earthworm to be distinguished from a roundwormO The toxin causes inappropriate firing of neurons leading to periods of rapid twitching that infected individuals experience as summation leading to tetanus. 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.
