Answer the following question given this paragraph: Old Faithful ( Figure below ) is the best-known geyser in the world. The geyser erupts faithfully every 90 minutes, day after day. During each eruption, it may release as much as 30,000 liters of water!. Q: What is the nickname of the best-known geyser in the world, which erupts reliably every 90 minutes? Choices: - old energetic - old consistent - victoria falls - old faithful A:
old faithful
Answer the following question given this paragraph: For feeding, the insect head contains one pair of lower jaws and two pairs of upper jaws. Insects have also evolved a wide range of specialized mouthparts for eating certain foods. You can see some examples in Figure below . Q: How many pairs of upper jaws do insects have? Choices: - four pairs - six pairs - three pairs - two pairs A:
two pairs
Q: Answer the following question given this paragraph: Proteins are biochemical compounds that consist of one or more chains of small molecules called amino acids. Amino acids are the monomers of proteins. There are only about 20 different amino acids. The sequence of amino acids in chains and the number of chains in a protein determine the protein's shape. Shapes may be very complex. You can learn more about the shapes of proteins at this link:. Q: What is the name for biochemical compounds that consist of one or more chains of small molecules called amino acids? Choices: - lipids - protons - hormones - proteins A:
A: proteins

It may lead to one species going extinct or both becoming more specialized. Q: Which competition leads to one species going extinct or both becoming more specialized? Choices: - intraspecific - beneficial - mimicry - interspecific A:
Answer: interspecific

**Answer**
mesophyll
Q: 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:
A: iron and magnesium
