- Food enters the small intestine - The small intestine produces hormones - The hormones cause the pancreas to produce enzymes for digestion - The enzymes travel from the pancreas to the small intestine through tubes - The enzymes help the intestines digest the food - The pancreas produces the hormones insuline and glucagon What might be the last step of the process?
Ans: The hormones control the amount of sugar in the blood.

- Solution caves are formed in limestone and similar rocks by the action of water - After a rain, water seeps into cracks and pores of soil and rock - The water percolates beneath the land surface - Some of the water reaches a zone where all the cracks and pores in the rock are already filled with water - Rainwater absorbs some carbon dioxide as it passes through the atmosphere and even more as it drains through soil and decaying vegetation - The water combines chemically with the carbon dioxide - A weak carbonic acid solution is formed What might be the last step of the process?
Ans: This acid slowly dissolves calcite, forms solution cavities, and excavates passageways

- A stream or river must occur - Through erosion, the stream cuts into the soil and bedrock - Through continuous erosion, a deep gash is cut through - After many years the river may dry up What might be the last step of the process?
Ans: A dry ravine is left

- A mushroom gives off gills lined with basidia - The basidia gives off spores - The spores germinate - The spores create Hyphae - Multiple Hyphae meet and converge - They join with Mycelium - A hyphal knot forms in the ground - A primordia shoots out of the ground What might be the last step of the process?
Ans: A mushroom cap is formed.
