A SimCell has a special membrane that is permeable to alcoho

A SimCell has a special membrane that is permeable to alcohol but not to water. This SimCell contains 20% alcohol and 80% water and is placed in a solution containing 40% alcohol and 60% water. What will happen to the cell? It will expand due to net movement of water into the cell. It will expand due to net movement of alcohol into the cell. It will contract due to net movement of water out of the cell. It will contract due to net movement of alcohol out of the cell. Fish that live in saltwater and fish that live in freshwater both have water balance challenges that deal with osmosis. What is the best characterization of the challenges for each, based on your investigations in this lab? Both types of fish must constantly get rid of excess water. Freshwater fish must get rid of excess water and saltwater fish must retain the water they have. Freshwater fish must retain the water they have and saltwater fish must get rid of excess water. Both kinds of fish must retain as much water as they can.

Solution

Q9 the answer is

IT WILL EXPAND DUE TO NET MOMENT OF ALCOHOL INTO THE CELL....becoz it is impermeable to waterbut permeable to alcoholand alcohol will move from a region of higher 40% to a region of lover 20% (inside cell) concentration

Q10

THE ANSWER IS

FRESH WATER FISH MUST GET RID OF EXCESS WATER AND SALT WATER FISH MUST RETAIN THE WATER THEY HAVE ..... becoz in saltwater fish ... water outside the fish is always salty .. so it always tries to move out from fish of body due to osmosis .....in order to cope with waterloss they must always retain the water ....vice versa happens in fresh water fish ... there inside of fish is more salty than surrounding water so water mover fromoutside to fishes body so it needs to get rid of excess water

SHOULD U NEED ANY FURTHER HELP KINDLY COMMENT ... I SHALL BE HAPPY TO EXPLAIN THE THINGS... U CAN ALSO SCHEDULE A CLASS WITH ME ON CHEGG AND WE CAN DISCUSS FURTHER ....
