Answer the following question given this paragraph: Look at this rusty bike. It has been left outside in damp weather too many times, so the iron in the metal parts has rusted. Iron rusts when it combines with oxygen in the air. Iron rusting is an example of a chemical reaction. In a chemical reaction, substances change into entirely different substances. For example, the iron in the bike and the oxygen in the air have changed into rust. Q: A rusty bike has been left outside in damp weather too many times, so the iron in the metal parts have? Choices: - melted - eroded - decayed - rusted A:
rusted
Q: Answer the following question given this paragraph: Absorption The mechanical and digestive processes have one goal: to convert food into molecules small enough to be absorbed by the epithelial cells of the intestinal villi. The absorptive capacity of the alimentary canal is almost endless. Each day, the alimentary canal processes up to 10 liters of food, liquids, and GI secretions, yet less than one liter enters the large intestine. Almost all ingested food, 80 percent of electrolytes, and 90 percent of water are absorbed in the small intestine. Although the entire small intestine is involved in the absorption of water and lipids, most absorption of carbohydrates and proteins occurs in the jejunum. Notably, bile salts and vitamin B12 are absorbed in the terminal ileum. By the time chyme passes from the ileum into the large intestine, it is essentially indigestible food residue (mainly plant fibers like cellulose), some water, and millions of bacteria (Figure 23.32). Q: The mechanical and digestive processes have one goal: to convert food into molecules small enough to be absorbed by the epithelial cells of what? Choices: - bile ducts - stomach cilia - alveoli - intestinal villi A:
A: intestinal villi
Question: Answer the following question given this paragraph: element: A substance that cannot be separated into smaller pieces. Defined by how many protons it has.

Answer the following question given this paragraph: Wings and feathers are two adaptations for flight that evolved in birds. Both are clearly displayed in the flying gull in Figure below . Wings evolved from the front limbs of a four-legged ancestor. The wings are controlled by large flight muscles in the chest. Feathers also help birds fly. They provide air resistance and lift. In addition, they provide insulation and serve other roles. Q: Birds adapted wings and weathers for flight during what process? Choices: - migration - variation - emergence - evolution A:
**Answer**
evolution
