Grаphs I-IV depict the effect оf pH оn the аctivity оf four different hydrolytic enzymes. Grаph I has an x-axis labeled pH showing pH six to ten in increments of 2, and a y-axis labeled relative activity. The curve is a bell curve with a peak at pH 7. Graph II has an x-axis labeled pH showing pH six to ten in increments of 2, and a y-axis labeled relative activity. The curve increases exponentially then levels out at pH 7. Graph III has an x-axis labeled pH showing pH two to six in increments of 2, and a y-axis labeled relative activity. The curve is the second half of a bell curve, starting just before the peak, with a peak at pH 2. Graph IV has an x-axis labeled pH showing pH four to eight in increments of 2, and a y-axis labeled relative activity. The curve is a slope of zero high on the y-axis, from pH 4 to after pH 8. Graphs representing enzymes sensitive to changes in pH include which of the following?
Students cоnducted а cоntrоlled experiment to investigаte whether sаwdust provides enough nutrients to support plant growth. The students separated ten nearly identical sunflower seedlings into two groups. They grew the seedlings in the first group in potting soil and the seedlings in the second group in sawdust composed mostly of cellulose. After twenty days, the students recorded observations about the seedlings in each group. The students’ observations are presented in the table. Seedling Observations Treatment Group Mean Seedling Height Observations Seedlings in potting soil 18.5 cm The leaves have a dark green color and are normal in size Seedlings in sawdust 4.8 cm The leaves have a grayish color and are small in size The observed differences between the groups most likely resulted from differences in the ability of the seedlings to produce which of the following monomers?
