Biology homewrk question. PLEASEhelp! Its about Bacteria/disease?

you may be resistant to a strain of bacteria...over time viruses/bacteria mutate and your t-cells, memory cells may not recognize them.... thus becoming prone for infection/disease.

You will find most of what you arel looking for regarding the first two question here: http://en.wikipedia.org/wiki/Food_production.  You will find your answer to question three here: http://en.wikipedia.org/wiki/Disease and as for the last one you will find here http://en.wikipedia.org/wiki/Clothing\n\nGood Luck :-)!!!

It is only A, Bacteria that applies to your question.

Bacteria, one-celled organisms visible only through a microscope. Bacteria live all around us and within us. The air is filled with bacteria, and they have even entered outer space in spacecraft. Bacteria live in the deepest parts of the ocean and deep within Earth. They are in the soil, in our food, and on plants and animals. Even our bodies are home to many different kinds of bacteria. Our lives are closely intertwined with theirs, and the health of our planet depends very much on their activities.\n\nMuch of our experience with bacteria involves disease. Although some bacteria do cause disease, many kinds of bacteria live on or in the human body and prevent disease. Bacteria associated with the human body outnumber body cells by ten to one. In addition, bacteria play important roles in the environment and in industry.\n\nWe have all had bacterial diseases. Bacteria cause many cases of gastroenteritis, sometimes called stomach flu. Perhaps the most common bacterial disease is tooth decay. Dental plaque, the sticky film on our teeth, consists primarily of masses of bacteria. These bacteria ferment (break down) the sugar we eat to produce acids, which over time can dissolve the enamel of the teeth and create cavities (holes) in the teeth.\n\nTooth decay provides a good example of how multiple factors contribute to bacterial disease. The human body hosts the bacteria, the diet supplies the sugars, and the bacteria produce the acid that damages the teeth.\n\nCommunities of bacteria form what are called biofilms on many body surfaces. Dental plaque is a biofilm covering the teeth. Biofilms also cover the soft tissues of our mouths and the inner surfaces of our nose, sinuses, throat, stomach, and intestines. Even the skin has bacterial communities that extend into hair follicles. Bacterial communities differ in each region of the body, reflecting the environmental conditions in their specific region. Bacteria that inhabit the surface of the stomach, for example, must deal with extremely strong acid in the digestive juices.\n\nSome regions in the interior of the body are sterile—that is, devoid of living organisms other than the cells of the body. Sterile regions include the muscles, the blood, and the nervous system. However, even these regions face constant invasion by bacteria. The body’s immune system is designed to rid the body of these invaders.\n\nA healthy, balanced community of bacteria is extremely important for our health. Some of these organisms protect us from disease-causing organisms that would otherwise infect us. Animals raised in a completely germ-free environment, without any contact with bacteria, are highly susceptible to infectious diseases if they are exposed to the outside world. Bacteria in our bodies also provide us with needed nutrients, such as vitamin K, which the body itself cannot make. The communities of bacteria and other organisms that inhabit the body are sometimes called the normal microflora or microbiota.\n\nFor the rest of this information, go to:)\n\nhttp://encarta.msn.com/encyclopedia_761574409/Bacteria.html

Bacteria is essential in the breakdown of matter.  Ecologically, bacteria breaks plant and animal matter down into nutritious soil for new plants to grow.\n\nEconomically? Compost, antibiotics, yogurt, etc. all need bacteria.  Also, if bacteria didn't help break down matter, we would have to pay to get rid of it.

Please take the time to\nvote for the best answer\n\nThank You!!\n\n\n\nCommonly known bacteria include such organisms as E-coli, Vibrio Colera, and Salmonella. They range in size from 0.2 to about 10 microns

There are many types of microbiological problems, and more than one solution for each.\n\nFor example, an infection caused to a bacteria (like the flu) is such a problem. A possible solution is an antibiotic from your doctor: it kills the bacteria and you get your health back.

Well, let me tell you that all bacteria are not harmful...they are normal flora of our body...exit on skin, intestine, nose and everypart of body....when are immune system goes down, these bacteria multiply and increase in size, some of them produce toxins and infect main organs of body like liver, kidney etc and cause dihrrohea...example is E. coli which is normal flora of instestine causes diarhhoea when immune system goes down...\n\nHope this helps!!!

bacteria, viruses, cyanobacteria or fungi?  or do you mean specific examples

If you are culturing someone who is sick - say someone who has pneumonia - then chances are the colonies that are all alike and have the greatest number on the plate are the ones causing the problem.  You run biochemical tests on them and determine if they are known pathogens.  Stuff gets complicated when you have someone with a bad immune system and the bacteria that are normally good are actually the bad ones.
