- What are the osmotic challenges faced by marine animals like fish? Describe how they cope with these challenges to maintain solute and water balance in their tissues.Goldfish are one of the most common aquatic pets. The average temperature to maintain healthy goldfish is between 72-75 degrees Fahrenheit. However, it is not unusual to find goldfish keeping office workers company in frigid cubicles as low as 68 degrees Fahrenheit. Mary noticed her goldfish opened and closed it’s operculum (protective covering for the gills) more often when the temperature in her office was warm. Worried, she may be harming her pet by keeping her office so cold, Mary set up an investigation to test the impact cold temperatures had on her goldfish’s respiration rate. Which of the following experiments would be best to investigate if goldfish maintain homeostasis during varying temperatures?A freshwater fish was accidentally placed in salt water. After several minutes in the saline water it died. What is the most logical explanation for its death?
- Most marine invertebrates are osmotic conformers. How does their body fluid differ from that of sharks and rays, which are also in near osmotic equilibrium with their environment?1) How do the plasma osmolarity and sodium concentrations of the body fluids in hagfish compare to that of teleosts and lamprey? A) Both are much lower in hagfish B) Both are much higher in hagfish C) Hagfish have a similar plasma osmolarity to teleosts and lamprey but a much lower sodium concentration. D) Hagfish have a similar Na+ concentration in their plasma to teleosts and lamprey but a much greater plasma osmolarity overall.In the aquatic world, osmoregulation is very important. Please describe what would happen at the cellular level as well as organismal level to a freshwater fish that is placed in salt water.
- The bodily fluids of freshwater fish contain higher concentration of dissolved solids in their surroundings, so they tend to bloat (take in water) or lose electrolytes. How can freshwater fish avoid this? 1.) By drinking lots of water? 2.) By actively transporting ions out from the gills into the water? 3.) by excreting highly concentrated urine? 4.) by resorbing ions in nephronsA saltwater fish has difficulty maintaining its levels of... 1.) Oxygen 2.) Ions 3.) water 4.) None of these 5.) All of theseWhy is the fish circulationclassified as a simple andcomplete circulation?
- Electron microscopy of kidneys revealed tubules, which are lined by cuboidal epithelium. There are light and dark cells in the epithelium. Light cells have a few organelles. The cytoplasm forms folds. These cells provide the reabsorption of water from primary urine into the blood. Structure and function of dark cells resemble parietal cells of the stomach. What tubules are presented on the electronogram? a. Collecting renal tubules b. Proximal tubules c. Ascending tubules loop of Henle d. Distal tubules e. Descending tubules loop of Henlewhat is osmotic pressure ? Why it is helpful ?1) A diver decides to take a balloon with him on a scuba diving excursion to a depth of 10m. The size (volume) of the balloon would _____. A) remain the same throughout the dive B) decrease on the way down and return to its original size on the way back up C) increase on the way down and shrink back to its original size on the way back up 2) How does the size of the air bladder compare between freshwater and salt water fish? A) freshwater fish have larger air bladders because they need to be less dense B) freshwater fish have smaller air bladders because they need to be less dense C) saltwater fish have larger air bladders because they need to be less dense D) freshwater and salt water fish have the same size air bladders because the air bladders play no role in osmoregulation or maintaining salt balance 2) Physoclistous fish fill their air bladders by _____. A) going to the surface and gulping air B) using the carbon dioxide that they produce through aerobic metabolism C)…
