Chapter 42, Problem 13TYU
Summary Introduction
To explain: The reason that adaptation in Argyroneta aquatica for storing air underwater is advantageous over having gills.
Introduction: The diving bell spider (Argyroneta aquatica) lives inside the water. It is dark brown in color, but the presence of hair on the abdomen makes it appear dark gray. It breathes air like other spiders. The air gets trapped by the dense hair on its abdomen and legs. This helps in breathing under water. The trapped air gives a silvery appearance. The diving bells are irregular sheets of silk and protein-based hydrogel. It allows the diffusion of gases but do not allow water to go through. The net diffusion of oxygen in and carbon dioxide out is maintained by the spider.

SOURCE:
Gills are the main site of gas exchange in almost all fishes. The gills consist of bony or cartilaginously stiffened arches that anchor pairs of gill filaments. In sharks, the pairs of gill filaments are separated by a fleshy septum. The numerous, minute lamellae that protrude from both sides of each filament are the primary sites of gas exchange; however, not all the blood flow in the gills is directed to the lamellae. "Nonrespiratory basal blood channels or venolymphatic simuses may carry a significant fraction of the gall blood found that resting rainbow trout perfused approximately 58% of their lamellae with blood. Trout in hypoxic (low dissolved oxygen) water or injected with epinepherine (eg. simulating stress or excitement) perfused more than 70% of their lamellae. Conversely, injections of acetylcholine decreased perfused lamellae to approximately 43%. These results indicate that rainbow trout can increase the number of lamellae that are used in respiration as the…

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 bloodarrow_forwardO 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.

Explain everything in three paragraphs.arrow_forwardWhen researchers first discovered that airflow through a bird’s paleopulmonal parabronchi is unidirectional, the question arose as to whether gas exchange is countercurrent, cocurrent, or cross- current. Some ingenious investigators carried out experiments in which they measured the efficiency of gas exchange between air and blood in duck lungs when parabronchial airflow was in its normal direction and when the direction of parabronchial airflow was artificially reversed. The efficiency did not change. How is this evidence against countercurrent and cocurrent gas exchange? How is this evidence for cross-current exchange?arrow_forward
