Answer:
Kinetic Energy and Potential Energy
Explanation:
When an object is in motion(ie.moving), it has kinetic energy. Energy stored in an object due to position and state, is called potential energy.
Cells have limitations, if the cell is stronger it targets other cells , when a cell is weak it possibly mean it’s disease.

The others are treatments. The purpose of a control group is used to increase the validity of the experiment by testing
the independent variable to check that it

Answer : The molar mass of unknown compound is 152.38 g/mole
Explanation :
Depression in freezing point = 
Mass of unknown compound = 16.5 g
Mass of water = 106.0 g
Formula used :
where,
= depression in freezing point
i = Van't Hoff factor = 1 (for non-electrolyte)
= freezing point constant for water = 
m = molality
Now put all the given values in this formula, we get
Therefore, the molar mass of unknown compound is 152.38 g/mole
