Describe how salmon achieve osmoregulation as they migrate between fresh and saltwater environments. b) Describe what happens to salmon in fresh water. What direction do solutes tend to move via diffusion? What direction does water tend to move via osmosis?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 river reached a flood that was passing through it. At a given instant, the storage of water in the reach was estimated as 20 Ha-m. What would be the storage in the reach after an interval of 3 hours, if the average inflow and outflow during the time period are 15 cubic meter per second and 10 cubic meter per second, respectively?In your travels around the Chesapeake Bay region, you have noticed that pink comb jellies (Beroe ovata) do not seem to be distributed evenly throughout the Bay. You suspect that this is because of environmental factors such as salinity, temperature, or the amount of oxygen dissolved in the water. You decide to pick one of these to test. Research question: Does salinity affect the distribution of pink comb jellies (Beroe ovata) in the Chesapeake Bay? After doing a little research in the literature, you discover that a common jellyfish (Aurelia aurita) prefers to live in higher salinity waters. (Comb jellies and jellyfish are not closely related, but since they are similar in structure, you hypothesize that they will react similarly to changes in salinity. a) Use this data, and sketch a graph by hand that would best fit the data. (think which type of graph would allow standard deviation to be included) b) Write an appropriate caption for your graph.Differentiate between the following types of movement observed on a wet mount or hanging drop slide:a. directional motility.b. Brownian movement.c. water current movement.
