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).
Best Answer: A homogeneous mixture is a uniform mixture consisting of only one phase, such as liquid, or solid in the case of an alloy. Also, for a homogeneous mixture, any reasonable amount of the mixture has the same composition and properties as the whole. Thus tap water is a homogeneous mixture. Heterogeneous mixtures are mixtures with an inconsistent, non-uniform composition. The constituent parts of a heterogeneous mixture can be mechanically separated from each other. Thus, orange juice is a heterogeneous mixture because you can use a filter to strain out the pulp and have a substance with different density, consistency, etc.
