Hypertonic solution means the solution with a lower water potential than the cell cytoplasm, such as salt water.
When the red blood cell is put into it, since the cell has a higher water potential than the solution, water molecules will flow from the cell back into the water due to osmosis.
Osmosis is always where water molecules flow from a region of higher water potential to lower, through a semi permeable membrane (Whcih is the red blood cell membrane in this case.)
Since water flowed out of the cell, the cell lose water and shrinks.
Hypotonic solution is where the solution that has a higher water potential than the cell cytoplasm.
So when the red blood cell is put in that solution, the water will flow from the solution into the cell this time, by osmosis.
The red blood cell will then gain so much water that the cell membrane cannot hold all and therefore burst.
Answer:
The correct answer is - A closed system exchanges all of its energy with its surroundings, and the scientist only measured the exchange of heat.
Explanation:
The amount of heat radiated is measured and analyzed by the marine biologist in this given experiment from an aquarium and on the basis of data the diagram is represented that states that the radiated energy is not constant over time and there are fluctuations.
It can not be considered as a closed system as energy is still exchange with the surrounding system, however, mass is not exchange but still, it cannot be called a closed system.

The answer is C.) Sac. More formally known as the amniotic sac. It's also sometimes called the bag of waters.
