Answer option:
1. duplicate themselves
2. convert energy
3. selectively exchange materials
4. all of the above
Answer:
4. all of the above
Explanation:
Cells carry out many functions. They are able to replicate their DNA and divide into two identical daughter cells in order to proliferate.
They can convert glucose into cellular energy (ATP) through respiration in the mitochondria
They can exchange materials with the outside environment via the selectively permeable cell membrane, endocytosis and exocytosis and active transport via membrane proteins. 
Therefore, all of the above is correct.

Answer:
osmolarity depends upon molarity.
glucose is a non-ionizing substance. it won't break down and will go as a whole.
osmolarity means the solute concentration of a solution.
here, the solvent is water.
therefore, 1 osmole = 1 mol
the ions of glucose after forming a solution (i) = 1
osmolarity = 1.5 M glucose × 1
                    = 1.5 osmoles of glucose.
