animals or plants. This conclusion was not made until Henri Dutrochet. Besides stating “the cell is the fundamental element of organization”, Dutrochet also claimed that cells were not just a structural unit, but also a physiological unit. In 1804, Karl Rudolphi and J.H.F. Link were awarded the prize for "solving the problem of the nature of cells", meaning they were the first to prove that cells had independent cell walls by the Königliche Societät der Wissenschaft (Royal Society of Science), Göttingen. Before, it had been thought that cells shared walls and the fluid passed between them this way. Credit for

obscure. The girl's name is variously given as Penelophon or Zenelophon. The Cophetua story was famously and influentially treated in literature by Alfred, Lord Tennyson ("The Beggar Maid", written 1833, published 1842); in oil painting by Edmund Blair Leighton ("The King and the Beggar-Maid") and Edward Burne-Jones ("King Cophetua and the Beggar Maid", 1884); and in photography by Julia Margaret Cameron and by Lewis Carroll (his most famous photograph; Alice as "Beggar-Maid", 1858). The painting by Burne-Jones is referred to in the prose poem "König Cophetua" by the Austrian poet Hugo von Hofmannsthal and in "Hugh Selwyn Mauberley" (1920), a

Tulsa Oilers. In Bloomfield's Major League debut — and his only Cardinal appearance — he was a defensive replacement for star Cardinal third baseman Ken Boyer in a 5–2 victory over the Chicago Cubs at Wrigley Field. Bloomfield was in the on-deck circle when the Redbirds made their final out of the game, and did not record a plate appearance. Drafted by the Twins during the off-season, Bloomfield spent most of the 1964 season with the Triple-A Atlanta Crackers. He started two games for the Twins as a second baseman on May 7–8. In the former, he collected his only

his expedition with Raleigh, Harriot wrote a treatise on navigation. He made efforts to communicate with Manteo and Wanchese, two Native Americans who had been brought to England. Harriot devised a phonetic alphabet to transcribe their Carolina Algonquian language. Harriot and Manteo spent many days in one another's company; Harriot interrogated Manteo closely about life in the New World and learned much that was to the advantage of the English settlers. In addition, he recorded the sense of awe with which the Native Americans viewed European technology: He made only one expedition, around 1585-86, and spent some time in the

sorters can positively or negatively identify one of the two desired fractions. A size range coefficient of approximately three is advisable. A minimum amount of undersized fine material must enter the machines to optimize availability. Moisture of the feed is not important, if the material is sufficiently dewatered and the undersize fraction is efficiently removed. For surface detection technologies sometimes spray water on the classifying screen is required to clean the surfaces. Surface detection technologies would otherwise measure the reflectance of the adhesions on the surface and a correlation to the particle's content is not given. During the more than

Hereford United respectively. Still's teams have been labelled as "fit and organised" and, even at clubs with small budgets, he has stated that he always employs a fitness and conditioning coach. Still has also said that he places attitude above ability, rejecting talented players who did not show ambition or willingness to self-improve. He has won praise for his man-management and talent spotting skills, especially his ability to discover young players in non-League football at the sixth tier and below, develop them and then sell them – often for a significant profit. Players that Still has developed that have gone

are." A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles. These viral particles, also known as "virions", consist of two or three parts: (i) the genetic material made from either DNA or RNA, long molecules that carry genetic information; (ii) a protein coat, called the capsid, which surrounds and protects the genetic

Fungi and many protists have some substantial differences, however. All animals are eukaryotic. Animal cells are distinct from those of other eukaryotes, most notably plants, as they lack cell walls and chloroplasts and have smaller vacuoles. Due to the lack of a cell wall, animal cells can transform into a variety of shapes. A phagocytic cell can even engulf other structures. Plant cells are quite different from the cells of the other eukaryotic organisms. Their distinctive features are: The cells of fungi are most similar to animal cells, with the following exceptions: Some groups of eukaryotes have unique organelles, such

bacterial phyla have species that can be grown in the laboratory. The study of bacteria is known as bacteriology, a branch of microbiology. There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water. There are approximately 5×10 bacteria on Earth, forming a biomass which exceeds that of all plants and animals. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the

Sex Organisms of many species are specialized into male and female varieties, each known as a sex. Sexual reproduction involves the combining and mixing of genetic traits: specialized cells known as gametes combine to form offspring that inherit traits from each parent. The gametes produced by an organism define its sex: males produce small gametes (e.g. spermatozoa, or sperm, in animals; pollen in seed plants) while females produce large gametes (ova, or egg cells). Individual organisms which produce both male and female gametes are termed hermaphroditic. Gametes can be identical in form and function (known as isogamy), but, in many

Polyploidy Polyploidy is the state of a cell or organism having more than two paired (homologous) sets of chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two sets of chromosomes—one set inherited from each parent. However, polyploidy is found in some organisms and is especially common in plants. In addition, polyploidy occurs in some tissues of animals that are otherwise diploid, such as human muscle tissues. This is known as endopolyploidy. Species whose cells do not have nuclei, that is, prokaryotes, may be polyploid, as seen in the large bacterium "Epulopiscium fishelsoni". Hence ploidy is
