Answer the following question given this paragraph: First, notice where carbon is fixed by the enzyme Rubisco. In C-3, C-4, and CAM plants, CO 2 enters the cycle by joining with 5-carbon ribulose bisphosphate to form a 6-carbon intermediate, which splits (so quickly that it isn't even shown) into two 3-carbon 3-phosphoglycerate molecules. Now look for the points at which ATP and NADPH (made in the light reactions) add chemical energy ("Reduction" in the diagram) to the 3-carbon molecules. The resulting glyceraldehyde-3-phosphate "half-sugars" can enter several different metabolic pathways. One recreates the original 5-carbon precursor, completing the cycle. A second combines two of the 3-carbon molecules to form glucose, the universal fuel for life. The cycle begins and ends with the same 5-carbon RuBP molecule, but the process combines carbon and energy to build carbohydrates food for life. Q: What elements do mafic minerals typically include? Choices: - iodine and magnesium - sodium and magnesium - xerophyte and magnesium - iron and magnesium A:
iron and magnesium

Answer the following question given this paragraph: Scientists measure the gases that escape from a volcano to predict eruptions. Gases like sulfur dioxide (SO 2 ), carbon dioxide (CO 2 ), hydrochloric acid (HCl), and water vapor can be measured at the site. Gases may also be measured from satellites. The amounts of gases and the ratios of gases are calculated to help predict eruptions. Q: Scientists measure the gases that escape from a volcano to predict what? Choices: - storms - floods - snowfall - eruptions A:
(Answer)
eruptions
