1 The faster-moving molecules cause the food coloring to mix into the water faster. 2  The water molecules and food coloring molecules in cold water donât move as quickly as in hot water. 3  The slower moving molecules result in slower mixing of the water and food coloring.
Order of Importance Example: Power Structure The Order of Importance organizational pattern can be difficult to identify alongside cause and effect and sequence text structures. In fact, in some cases one could use the same graphic organizer to represent information from an order of importance and sequence passage. The difference is subtle and must be inferred at times, but generally a sequential passage explains the steps that occur in a process.

E. coli, remember, is a prokaryote; an organism whose cells lack a nucleus. Prokaryotic DNA is clustered into groups of genes called operons. When scientists first studied the lac operon found in E. coli, they observed gene regulation through transcriptional repression and induction.We've talked about repression and induction before. Repression describes a decrease in gene transcription, whereas induction is an increase in gene transcription.e call the individual genes structural genes. A structural gene is any gene that codes for a structural protein or an enzyme. Remember, enzymes are just one kind of protein. The structural genes in the lac operon code for three different enzymes.
