ps://d2l.pima.edu/content/enforced/438955-30911.201830MuSTAUS OSinUS 3. Sharks living in the ocean are isotonic to their environments, that is, the concentrati solutes inside their cells is the same as the concentration of solutes in their external environment. How will osmosis affect shark cells in their natural environment? .a. Osmosis will not affect shark cells, because there will be no net movement water into or out of the cells. . b. Osmosis will cause water to enter the cells, making them larger . c. Osmosis will cause water to leave the cells, causing the cells to get smaller .d. Osmosis will make the shark cells hypertonic to their environment . e. Osmosis will make the shark cells hypotonic to their environment 4. Suppose an absent-minded aquatic biologist accidentally puts a freshwater fish in a saltwater aquarium. Thus, saltwater would be free to enter the fish and surround its body cells. What would happen to the cells of this fish? a. Osmosis will not affect the fish's cells, because there will be no net movement water into or out of the cells b Osmosis will cause water to enter the fish's cells until they burst . c. Osmosis will change the fish's cells such that it is now adapted for a saltwater environment d. Osmosis will cause water to leave the fish's cells, making the cells collapse e Osmosis will cause water to flow from the hypertonic cells to the hypotonic aquarium 5 Suppose an absent-minded aquatic biologist accidentally puts a saltwater fish in a freshwater aquarium Thus fresh water would be free to enter the fish and surround its bod cells What would happen to the cells of this fish? . a Osmosis will not affect the fish's cells be cause there will be no net movement ofExplanation / Answer
3. The answer will be a.
As sharks are isotonic to the water then no change will be their body.
There will be no net movement.
4. d
As salt water is hypertonic and fish is hypotonic then water from the fish's body will move outside causing fish to shrink and die.
If a cell is kept in hypertonic solution it shrinks.
When a cell is kept in a hypotonic solution it swells.
When a cell is kept in an isotonic solution there will be no change.
