Ascientist was studying a population of elephants. the first year, he counted a population of 80. over the next eight years, the population’s numbers were 94, 100, 103, 110, 125, 120, 125, 120. the population never exceeded 125. what is the carrying capacity for this population?

Lactase is essential for digesting lactose in milk. this enzyme is specific for this sugar. why? molecules and active sites vary in size; only properly sized molecules can fit.there is a precise compatibility between the active site and the lactose molecule.specificity refers to the action of the enzyme, such as hydrolysis, and relatively few molecules can be hydrolyzed.reaction-specific enzymes assume a fit by folding around the most numerous substrate molecules.
