Jet streams are like rivers of wind high above in the atmosphere. These slim strips of strong winds have a huge influence on climate, as they can push air masses around and affect weather patterns.
Arteries carry blood to different parts of our body. They divide into branches called capillaries to supply blood to even small organs. So, we compare arteries with tree that divides into smaller and smaller branches. Capillaries again merge and form veins to collect impure blood
Warm blooded animal maintain their temperatures at a constant.When it is cold they generate heat to keep themselves warn,they also try to cool themselves when it is cold. This animals include Human-beings and Dogs
At room temperature or about 25°C, potassium nitrate (KNO₃) has a solubility of about 38.7 grams per 100 mL of water. At this concentration, the KNO₃ solution is said to be saturated since it already contains the maximum amount of solute that the solvent can dissolve, thus, if you add more KNO₃ salt, it will no longer dissolve. When the solution has less solute than that of the saturation concentration, it is called an unsaturated solution, thus if you add more solute, the KNO₃ salt will still dissolve. If the concentration of the solution is greater than its solubility, the solution is said to be supersaturated, thus, if excess KNO₃ salt is added, crystals will start to form.
