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).
Mixtures can usually be separated by mechanical means. There are two different types of mixtures: homogeneous mixtures (including solutions, colloidal dispersions and suspensions), and heterogeneous mixtures. Homogeneous mixtures Homogeneous mixtures are mixtures that have definite, true composition and properties. For example, any amount of a given mixture has the same composition and properties. Examples are solutions and some alloys (but not all). Homogeneous mixtures can also be called pure substances. A homogeneous mixture is a uniform mixture consisting of only one phase. Examples are gasoline and margarine. Heterogeneous mixtures
