Answer:
Well for the onion peel, since its a plant cell...it shall gain water from the solution as it has a lower water potentail,and hence increase in size, becoming turgid and tight, with the cell wall exerting pressure to stop it from bursting.
For the RBC, its an animal cell, and shall also gain water, but since there is no cell wall to support it, it shall soon gain so much water that it shall burst becuase of the pressure, through lysis, and shall die.
Note, the plant cell does not die.
According to the activation-synthesis theory of dreaming, the source of a dream is neuronal firing in the lower brain stem. It is also known as the medulla oblongata or just medulla. It is essential in processes like blood pressure and heart rate. Also, it is responsible in a number of reflexes in the body or the involuntary actions like coughing, sneezing and vomiting. It is said to contain cells that would turn REM on and off. From recent research, it is the part of the brain that is the origin of the electrical impulses where dreams are results. It is connected to other parts of the brain which controls memory, movement, hearing and vision.
