How much water can a camel store in its hump ? •Camels do not store water in their humps. Instead, camels use the humps to store energy-rich fat deposits.  •Many animals, including humans, use body fat as an energy storage. •Unique to a camel, however, is the fact that it stores the fat in a hump up on top instead of around the belly or limbs.  •It does this to stay cool. Fat has a natural tendency to insulate heat, acting like a blanket to bodies that are covered in fat.  •Being a hot-climate animal, a camel would waste energy trying to cool down if its fat were wrapped around its body. •Instead, by placing the fat in a hump that is out of the way, the camel can stay as cool as possible while still having an energy reserve.  •Think of it like a tourist from northern Siberia with a coat stuffed full of snacks just stepping off the plane in the Sahara Desert. What does he immediately do? He takes off his coat and slings it over his shoulder. He still wants ...

How do trees give earth all its oxygen ? •All of earth's oxygen does not come from trees.  •Rather, the atmospheric oxygen that we depend on as humans comes predominantly from the ocean.  •According to a study, about 70% of the oxygen in the atmosphere comes from marine plants and plant-like organisms. •These ocean-living plants release molecular oxygen as a waste product of photosynthesis (as do most plants). •In photosynthesis, plants capture sunlight and use its energy to split carbon dioxide and water, making sugar for itself and releasing oxygen as a by-product. •The dominance of ocean life as earth's top oxygen producer makes sense when you consider that the majority of the earth is covered with ocean. •Of the different types of marine life providing oxygen, the dominant class is phytoplankton.  •Phytoplankton are microscopic photosynthesizing organisms that live in water.  •Phytoplankton includes cyanobacteria, green algae, diatoms, and dinoflagellate...
