I. Three different representations of glucose are
given below. Identify each type
of model.

Ball and stick model is 3D and has the atoms depicted as different Coloured balls Conected to each other by "sticks"

fischer projection has the atoms on the side coming out of the plane, the atoms at the ends going behind (going away from you)

bond line notation Is the most common it does not show the C or H bonds but instead carbons are represented by the bends

dynamic equilibrium is the answer.
