In cell division, the cell that is dividing is called the "parent" cell. Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing.
The inducer deactivates the repressor protein. This allows
the gene which the repressor protein suppresses, to be actively transcribed.
When the inducer fits in its allosteric site on the repressor protein, the repressor changes conformation and is not able
to bind the operator site of the operon.
Answer:
The most appropriate answer would be Competition between two species may force one of them to migrate to survive.
Competition is a type of biological interaction in which organisms of same or different species compete for similar resources essential for their survival in an ecosystem.
Organisms can compete for limiting sources (such as air, water, food), territory, and mating rights.
In inter-species competition, species with the slightest advantage will grow and result in the migration or extinction of other species in that ecosystem.
Thus, the population of other species would decrease or extinct in that ecosystem.
For example, lion and cheetah may compete for their common prey that is, deer.
