- Hello, May I get help on this question very soon please? I do not understand it. Scenario: Chris M is a scientist who studies a species of fish that only lives in some desert lakes at the bottom of Death Valley, California. Death Valley is about 282 feet below sea level. He notices that he feels like he can breathe a little better down there than at his home at sea level. He comes to you, his best friend who is a physiologist, and he asks why? You tell Chris… (see image)O The toxin causes inappropriate firing of neurons leading to periods of rapid twitching that infected individuals experience as surnmation 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 sve and submit.

- This is a three-part question You want to measure the blood oxygen level in a drop of blood using a pulse oximetry device. If you have a light source at 700nm, and 1mm of path length, what must be the concentration of: - oxidized hemoglobin in blood so that the light intensity at the output decreases to one tenth of the input intensity? - reduced hemoglobin in blood so that the light intensity at the output decreases to one tenth of the input intensity? - at the concentration you found in the second part, what is (Ii/If) for oxidized hemoglobin?The atmosphere that we breathe is about 21% oxygen, and our respiratory system has evolved to allow us to thrive at that concentration. However, breathing air with a lower concentration of oxygen is difficult for us, or even fatal (although some other animals can do it). Using your knowledge of normal human respiration, describe two specific modifications to our respiratory system that might improve our respiratory function and allow us to survive at lower oxygen levels (hint: think about things like diffusion, surface area, and oxygen-carrying ability).What is the biophysical reason that myoglobin (as opposed to hemoglobin) could never play the role of the oxygen transport system in the human body? 1. It binds oxygen too tightly 2. It binds oxygen too weakly 3. It binds oxygen too slowly 4. It does not bind oxygen cooperatively
- 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 bloodOur human hemoglobin is 100% saturated near the alveoli and 80% saturated after passing through the systemic capillaries and moving back into the veins. By contrast, an extraterrestrial friend's oxygen-binding molecule is 100% saturated near their alveoli and 60% saturated after passing through their systemic arteries and moving back into the veins. How does his hemoglobin compare to yours? a. they deliver a larger share of oxygen to their tissues at rest b. the partial pressure of O2 in their alveoli is higher than ours c. the oxygen- binding molecule in their circulatory system is worse than ours d. the partial pressure of O2 in their tissue is lower than oursGiven this information, and given your knowledge of what gases were thought to be present on ancient Earth, which of the following might be the function hemoglobin would have served in the earliest cells? Hemoglobin originally served to assist in the rudimentary stages of electron transport chains, as they are seen in animals currently. Hemoglobin helped to bind oxygen and deliver it to the components of ancient photosynthesis, as oxygen served as an electron carrier. Hemoglobin originally bound to nitrogen gas and help in the production of proteins and nucleic acids. Hemoglobin bound to oxygen and kept it away from other molecules in the cell, as oxygen is highly reactive and might cause damage to those molecules.
- Hello, May I get help on this question very soon please? I do not understand it. Question: You're talking to one of your grandparents on the phone, and they are telling you about some really neat things they just learned about the lungs on a documentary. Specifically, they are telling you about this really cool feedback loop where lower in CO2 in the blood in near skeletal muscles than usual to leads your brain to trigger a whole bunch of responses in how you breathe. They mention about how your medulla tells your systemic arterioles to constrict, for your external intercostals to contract less, and your lung muscles to contract less. You tell them how much you love to hear that they are learning about the respiratory system, but you gently note that the documentary must have got one thing wrong. The documentary was incorrect because (see image)Nature of Science Ethical implications of research The use of animals in experiments may generate ethical issues. These are discussed in Appendix 3: Defining ethics and making ethical decisions on the accompanying website.
