When spherical bacteria occurs in pairs,they are called.....?

First, to achieve success in school, spend some time doing research. In the time it took to post a question in Y!A you could have used a seach engine and come up with the answer in seconds.\nbecause it is so easy to find, I will go ahead do a brief rundown on spherical bacteria.\n\nSperical cells are round and are called 'cocci' (singular coccus). They may be true spheres (eg. staphylococci), or irregular helmet-shaped (eg. pneumococci), or kidney-shaped (eg. Neisseriae, Vibrio). \n\nCocci may occur alone, in pairs, or in groups. \nIf found in pairs they are called diplococci.\nIn a group of three they are a triad, etc. \nOthers include: Tetracoccus (groups of four), Streptococcus (chains), Sarcina (cubes of eight), and Staphylococcus (irregular clusters). \n\nThis group can cause many diseases in humans and animals. Some include the following: pneumonia, throat infection, strep throat, bacterial heart disease, meningitis, septicemia (blood poisoning), and various skin diseases including fleash eating disease.\n\nIf you were not doing a homework assignment, I apologize for chastizing you. In order to be successful in research, you have to lay a good foundation.

Some Bacteria divide every 20 minutes

At school I was taught that they repreduce by binary fission. I'm sure though that mitosis does ot occur due to the fact that bacteria does not possess a nucleus, therefore mitosis can't occur. \n\nI'm not sure over prokaryotic fission, but my answer would be D, if I had encountered that question.\n\nUse the following as an ideal answer: http://www.expage.com/binaryfission

No, plantkon are just very small plants and animals. They are not single celled organisms, but if they were, that wouldnt automatically make them bacteria. Bacteria can only be prokaryotic organisms.\n\nBacteria are constantly being eaten. There is bacteria on everything you eat, and very often, bacteria is used in the production of food.

Yes. They are probably microbes or even smaller nanobacteria. \n\nI have seen the work of Dr. Robert Folk at the University of Texas, who examined the Martian meteorites found in Antarctica and found possible fossil evidence of nanobacteria. Many biologists are not convinced that nanobacteria (which are measured in nanometers) even exist and argue that they are too small to contain the functions of a living cell. The topic remains controversial.   \nHere is a page discussing the biological controversy (there are some geological controversies as well):\nhttp://serc.carleton.edu/microbelife/topics/nanobes/index.html\n\nHere is the NASA page describing the findings:\nhttp://nssdc.gsfc.nasa.gov/planetary/marslife.html

Bacteria.Bacillus form little rods.Micrococcus consists of single rounded cells.Streptococcus forms chains of rounded cells.Sarcinae  occur in irregular cubes and Spirillium is spiral in form.

hmm none of them sound completely correct, but A and E seem the most correct and E is probably the one considered correct by the person doing the grading, since A is rare among bacteria, but still occurs, and  E is rare that prokaryotes do not use this method of reproduction.

Haemophilus is a genus of Gram-negative pleomorphic coccobacilli bacteria. While Haemophilus bacteria are typically small coccobacilli, they are categorized as pleomorphic bacteria because of the wide range of shapes they occasionally assume. The genus includes commensal organisms along with some significant pathogenic strains such as H. influenzae—a cause of septicemia and bacterial meningitis in young children—and H. ducreyi, the causative agent of chancroid.\nHaemophilus species are classified by characterization of their capsule: seven serogroups exist, a—f and e′. Capsule type b (Hib) is the most clinically significant because of its virulence.\nIf you want to read the full article about it, please visit the following link:-\nhttp://en.wikipedia.org/wiki/Hemophilus

Bacteria have very few chromosomes compared to us, so there must be a very simple bacteria with only 1 chromosome.  Their chromosomes are circular and are called plasmids.

It is eubacteria. I just studied that.

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

It is a decomposition reaction that is taking place under the action of bacteria.

These cells are called 'spores'.

A bacterium is a microscopic unicellular organism with a simple cell structure, they procreate by fission, that is splitting and sharing DNA.\n\nA virus is a submicroscopic parasite which invades living cells, including bacteria, and hijacks the cell's systems to force the cell to make copies of the virus.

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

Staphylococcus albus (the white Staphylococcus) is spherical bacteria forming clusters. From that characteristic comes the name ( Staphyle - Greek for a bunch of grapes). S albus is the most frequent skin bacteria. It has been considered an innocent partner living on the skin surface of all of us and it has been found in about 30 % of all clean orthopedic operation wounds- all of these wounds healed without complications. This friendly coexistence between the people and the white Staphylococcus changed with the advent of total hip operations. \n\nWhen Staphylococcus albus colonizes the surfaces of total joints, it changes from doctor Jekyll to doctor Hyde. Once fixed to the surface of the total joint prosthesis, S. albus develops a slime cover and changes its characteristics: it develops resistance to antibiotics and causes slow, indolent infections around total joints.\n\nI hope I have been of help.
