Q: Answer the following question given this paragraph: Stems are organs that hold plants upright. They allow plants to get the sunlight and air they need. Stems also bear leaves, flowers, cones, and smaller stems. These structures grow at points called nodes. The stem between nodes is called an internode. (See Figure below . ). Q: What is the basic structure that holds plants upright, allowing plants to get the sunlight and air they need? A:

OPTIONS:
- twig
- stamen
- root
- stem

A: stem

input: OPTIONS:
- stomach
- lungs
- pancreas
- heart Now, answer this question: Answer the following question given this paragraph: When you think of muscles, you might think of biceps and the external muscles you see in a bodybuilder.

Q: Answer the following question given this paragraph: Many adults and some children suffer from a deficiency of lactase. These individuals are said to be lactose intolerant because they cannot digest the lactose found in milk. A more serious problem is the genetic disease galactosemia, which results from the absence of an enzyme needed to convert galactose to glucose. Certain bacteria can metabolize lactose, forming lactic acid as one of the products. This reaction is responsible for the "souring" of milk. Q: Many adults and some children suffer from a deficiency of lactase. these individuals are said to be lactose intolerant because they cannot digest the lactose found in what? A:
Answer: milk
