Answer:
Independent variable: Glass of milk
Dependent variable: Time of sleep
Control variable: same type of milk
Explanation:
Independent variable in an experiment refers to the variable that the experimenter manipulates or changes in order to get a response in another variable (dependent). In this case, the independent variable is the GLASS OF MILK taken before bed.
Dependent variable is that variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the TIME OF SLEEP of the students.
A control variable or constant is the variable that is kept unchanged throughout the course of the experiment in order not to alter the outcome of the experiment. In this experiment, a control variable can be the SAME TYPE OF MILK taken by each student.

Answer:
The correct answer is "a hypertonic solution".
Explanation:
Seawater is the most clear example of a hypertonic solution in nature. The concentration of ions in seawater are far more superior than the concentration of ions inside a plant or an animal cell, since seawater have an osmolarity of about 1000 mOsm/l. Therefore, at high tide a plant or animal cell will be in a hypertonic solution, and the cells must have adaptions to avoid cell shrinking and dead.
The eruption of Mount St. Helens provided a prospect for the scientists to examine the effects of the catastrophe. In the eruption, the losses were tragic, however, after the incident, the geologists hugely bettered their tendency to determine eruptions, by safely evacuating thousands of Filipino people prior to the eruption of Pinatubo in 1991.
Scientists also started to learn various other valuable lessons, even some of them have defied the fundamentals of evolutionary thinking. The eruption of 1980, offered a natural laboratory for comprehending that how quickly the catastrophic procedures can reshape the globe, and how briskly wildlife can recover.
