A. A 1/4-ounce envelope of unflavored gelatin contains 1 tablespoon, which is enough to gel about 2 cups of most clear liquids. Keep in mind that certain foods-figs, ginger root, guava, kiwifruit, papaya, and pineapple-contain an enzyme that prevents gelatin from thickening.
Upwelling in the coastal ocean can be due to a number of factors. In most situations the upwelling is wind driven and its effect on currents, stratification and nutrient supply determined by topographic detail such as water depth and the shape of the coastline.
Both phytoplankton and zooplankton feed fish. Most of the upwelling in the ocean occurs in two settings: coastal upwelling along the shores bathed by eastern boundary currents (that is, along the eastern portions of the great central gyres) and equatorial upwelling along the equator.
