seedling because many plants do not bring their cotyledon s above the soil surface when they germinate as the seedling shown to the left did Here are some key features to look for to determine whether a plant is a monocot or a dicot Leaves of dicots have veins that are branched Sometimes the veins branch out on either side of the leaf

Extracting Gold

To isolate pure gold mining companies use a complex extraction process The first step in this process is breaking down large chunks of rock into smaller pieces At a mill large machines known as crushers reduce the ore to pieces no larger than road gravel The gravel like material then enters rotating drums filled with steel balls.
