3. Biologists investigated the effect of the presence of aluminum ions on root tips of a varicty of wheat. They removed 2-mm sections of the tips of roots. Half of the root tips were placed in a nutrient solution with aluminum ions, while the other half were placed in an identical nutrient solution without aluminum ions. The length of the root tips, in millimeters, was measured every hour for seven hours. The results are shown in the data table below.

Mark an appropriate scale on each axis. b. Plot the data for root tips in the solution with aluminum ions on the grid. Surround each point with a small circle and connect the points. Example: c. Plot the data for root tips in the solution without aluminum ions on the grid. Surround each point with a small triangle and \ connect the points. Example:

39 You are growing tomatoes and your plants are healthy and nearly one metre tall. Youworry that they might get blown over by the wind, so you decide to lend them extrasupport with a wire frame. You accidently break the growing tip off the top of one ofthe plants. After a few weeks, you notice that instead of growing tall like the otherplants, the plant with the broken tip has grown denser with thicker lateral shootsthan the other plants.Answer the following questions in sentence format, that are related to the abovecase study. bc) What three plant hormones (plant growth regulators) and signaling moleculeare involved? And What hormone could you apply to the cut tip to reduce lateral shootdevelopment?
