Bacteria are some of the best examples of prokaryotic organisms. These organisms do not have a membrane-bound nucleus and lack the well-distinguished cell features found in eukaryotes.Know More
Specific examples of prokaryotic organisms include the Escherichia coli bacterium and the Streptococcus bacterium. These are more recognizable as E. coli, a bacteria often found in meat, and the bacteria that causes strep throat.
There is an entire kingdom devoted to prokaryotes, named Archaebacteria. These prokaryotes are ancient forms of bacteria and are notable for living in extreme conditions, such as geothermally active pools and extremely acidic waters. They are considered to be the oldest living organisms on the Earth.Learn more about Biology
Living things need air, food and water because they are essential to the chemical processes that provide organisms with energy and keep them alive. These processes are collectively known as metabolism. The nutrients found in food, the oxygen found in air and the solvent property of water are indispensable components of metabolism.Full Answer >
Clostridium difficile bacteria are organisms that live in the human digestive tract. Normally, C. diff causes no problems; however, under certain circumstances, imbalances allow it to grow out of control. The bacteria then release toxins that attack the lining of the intestines, causing colitis.Full Answer >
According to the University of Colorado, organisms in the phylum Protazoa are the animal-like members of Kingdom Protista. These organisms are mostly single-celled, although there are several multicellular protist species. All protists obtain nutrients by feeding on other living things, and they are mobile. Their cells are eukaryotic and contain developed organelles, but they lack cell walls.Full Answer >
A biology investigatory project is a project involving a combination of research and scientific experimentation that relates to the study of living organisms. Investigatory projects typically lead to a final presentation at an exhibit or science fair, or a report.Full Answer >
