This is a series of extension questions to use in conjunction with the published HHMI activity which examines the ability of humans to digest lactose (see accompanying link).  

Using lactase persistence as the model,, these question in conjunction with the HHMI activity do the following:

1.Introduce students to the digestive system & enzymatic digestion.

2.Apply previously learned knowledge of acid-base balance via blood and respiratory system to digestive system processes.

3.Introduce students to movement of water between body compartments.

4.Reinforce genetic inheritance and natural selection concepts.
