Pneumonia is an infection of the lungs. People with pneumonia usually complain of coughing, mucus production, fever, shortness of breath, and/or chest pain. 1  The body's immune system usually keeps bacteria from infecting the lungs.2  In bacterial pneumonia, bacteria reproduce in the lungs, while the body tries to fight off the infection. Inflammation is the body's attempt to destroy infection, and causes many of the other symptoms of bacterial pneumonia, including fever and chest pain. 2  Pneumonia can be very serious, because it directly interferes with the body's ability to exchange carbon dioxide and oxygen.
Homogeneous mixtures have uniform composition and properties throughout and are known as solutions. For e.g, when sugar/salt is dissolved in water it forms a solution in which â¦ the sugar/salt and water are uniformly mixed (the sugar is dissolved uniformly in water).
A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties. A heterogeneous mixture is a type of mixture in which the components can be seen, as there are two or more phases present.One example of a mixture is air.Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances. Salt, sugar, and many other substances dissolve in water to form homogeneous mixtures.A homogeneous mixture in which there is both a solute and solvent present is also a solution. heterogeneous mixture is a type of mixture in which the components can be seen, as there are two or more phases present. One example of a mixture is air. Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.
