To demonstrate the principle of Osmosis and to apply it with actual life situations. Materials and Methods: • Materials: Compound microscope Glass Slide Cover

Both alligators and crocodiles are members of the reptilian order Crocodilian. But the families they belong to‚ Alligatoridae and Crocodylidae. As a group‚ crocodilians are pretty impressive animals: Their lineage goes back 240 million years‚ meaning they’ve outlived the dinosaurs by a good 65 million years. Ideally suited for life in water and on land‚ members of the order can swim up to 20 mph and run up to 11 mph. Crocodiles and alligators are top-notch hunters and will eat just about

overuse of water.[3] A water crisis is a situation where the available potable‚ unpolluted water within a region is less than that region’s demand.[4] Water scarcity is being driven by two converging phenomena: growing freshwater use and depletion of usable freshwater resources.[5] "In Meatu district‚ Shinyanga region‚ Tanzania‚ water most often comes from open holes dug in the sand of dry riverbeds‚ and it is invariably contaminated."
