Oligomeric enzyme have more than one polypeptide chain and the enzyme show positive cooperativity. It means that binding of the ligand to the enzyme will help other ligands to bind to the enzyme. Hill cofficient is used to measure the determining the degree of cooperativity of the binding between enzyme and substrate or ligand. As in this case, allosteric enzyme show positive cooperativity, its Hill cofficient will increase
If immigration and emigration numbers remain equal, decreased birthrate could cause a slowed growth rate
.
Decreased birthrate always affects the numbers in terms of population.The less births there are, the smaller the number of people. Even if the death rate remains constant a decreased birthrate will slow growth of population.
