[LONG ANSWER/4 questions] Two groups of cloned seeds from a lima bean plant are grown under two conditions:
1) normal soil (NORM),
2) soil that is high in pollutants and low in nutrients (HI-LOW).

The plants that grow from seeds in the HI-LOW soil grow shorter than the plant they came from and have lower seed production than plants grown in the NORM soil. Both groups of plants have offspring in the same soil type, and the new generation looks exactly the same as the previous generation, with HI-LOW plants being shorter than NORM plants.

a. Is this an example of adaptation?

b. What is causing the observed differences in appearance?

c. Are these differences heritable?

d. How might you test if this is heritable and/or if this is an adaptation?

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.
