b) causes gas, cramping and diarrhea
c) more common with age
d) all of the above

Answer 1

Lactose intolerance is a condition characterized by the inability to digest lactose, resulting in symptoms such as gas, cramping, and diarrhea. It is caused by a deficiency or absence of the enzyme lactase and is more common in adults, especially certain populations.

Step-by-step explanation:

Lactose intolerance is a condition characterized by the inability to digest lactose, the sugar found in milk. It is caused by a deficiency or absence of the enzyme lactase, which is responsible for breaking down lactose. Symptoms of lactose intolerance include gas, cramping, and diarrhea. Lactose intolerance is more common in adults, especially among certain populations such as Asians, and is a result of decreased lactase production as they age. Therefore, all of the options given in the question (a) is due to an enzyme deficiency, b) causes gas, cramping, and diarrhea, and c) is more common with age) are correct.
