The given statement can be completed as-

The main difference between a prokaryotic cell and a eukaryotic cell is the presence of a true nucleus in eukaryotes.

Eukaryotes are those organisms, which possess a membrane bound nucleus ( true nucleus in the cell) that contains the genetic material ( DNA) of the living organisms. The eukaryotic cells also contain membrane bound subcellular organelles like endoplasmic reticulum, golgi complex, mitochondria.

Example- Plants and animals.

Prokaryotes are those organisms that do not possess a membrane bound true nucleus and subcellular organelles. The genetic material lies in the cytoplasm of the cell.

Example- Bacteria like E.coli.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
