C. leptin, pancreas/gallbladder

D. leptin, microvilli/villi

5) What is lactose intolerance?  

a. Lack of lactase production, meaning you can’t break down/digest it b. Too much lactose production, meaning you store excess as fat c. Lack of working lactose receptors We also discuss several other topics like What is the study of how organisms interact with one another and with their environment?

d. A psychosomatic food sensitivity not diagnosed by doctors

6) Based on a 2000 calorie diet, how many hours of energy will this food give you? > a. less than 1 hour

b. 6 hours

c. 8 hours

d. 3 hours
