In Texas, when talking about minerals, the mineral material people are discussing is petroleum products like oil and gas. These are considered "minerals" by the law. Also, due to their high price, they are often emphasized over actual minerals (by the scientific definition). Although Texas is the home to a considerable amount of oil and gas, the state also holds a rich amount of non-petroleum mineral and rock material. In the following link, the Texas Almanac lists many of these materials, describes where they are found, and what they are used for. Read through the list and find two of these resources that interest you. On the discussion board, create a post and discuss how these two materials might be used by you in your life.

Interpret the model. a three-part model with black right-arrows between the parts. left part: a large green apple-shaped component with a w-shaped indentation centered on top. a small blue apple-slice shape sits above the left indentation and an arrow points from the shape to the indentation. a small purple apple-slice shape and arrow sit above the right indentation and an arrow points from the shape to the indentation. middle part: a large green apple-shaped component with a square indentation centered on top. sitting in the left side of the indentation is a blue apple-slice shape with a flat bottom, fused to a purple apple-slice shape with a flat bottom on the right side of the indentation. right part: a large green apple-shaped component with a w-shaped indentation centered on top. an up-arrow is centered above the indentation pointing to a fused blue and purple apple-slice-shaped flat-bottom component sitting above the indentation. assigne "true" or "false" to the end of each statement. the model shows a shape change occurring in the enzyme after the substrate is bound in the active site. t/fthere are two products in this model. t? f there are three substrates in this model. t/f the model shows two different enzymes. t/f
