(around 400 BCE). Democritus thought matter could be divided into. . smaller and smaller pieces until a . single indivisible . particle is reached. . He named this particle the . atom. He proposed that atoms are of different sizes, in constant motion, and separated by empty spaces.. The Cell Theory:. . 1. . All life forms are made from one or more cells. . 2. . Cells only arise from pre-existing cells. . 3. . The cell is the smallest form of life. . . Types of Cells:. Prokaryotic. On your bell work . sheet, answer the following.. When . are zeros significant? . . When . do you use the fewest number of Significant Figures?. Objectives. The Structure of the Atom. Properties of Subatomic Particles. 2. The Atom. All matter is composed of atoms.. An atom is composed of three subatomic particles: electrons (-), protons (+), and neutrons (0). The nucleus of the atom contains the protons and the neutrons (also called nucleons.). Kelly . Bushouse. , Cap Kelly, and Connor O’Neill. What is the nucleus?. . The nucleus is the control center of the cell.. Hereditary information is stored as DNA and RNA in the nucleus.. The nucleus controls reproduction, movement, eating, and more.. In the nuclear equation for alpha decay, the mass number of the new nucleus decreases by 4 and its atomic number decreases by 2.. Learning Goal . Write a balanced nuclear equation showing mass numbers and atomic numbers for radioactive decay.. Q1 FY 15 Investor Presentation. 1. Nucleus a GLOBAL LEADER in “Retail Lending Solutions. ” .

The hydrogen envelope is about 10 million km across at the nucleus of the comet and about 100 million km long.. 1. . Cell . Theory. All. living things are made of . cells..

Robert Brown. 1773-1858. -Discovered in 1831 by Scottish botanist Robert Brown. -Suggested . the nucleus played a key role in fertilization and development of the embryo in plants. Some History of the Nucleus. Was discovered by Ernest Rutherford, a New Zealand born British physicist, in May of 1911.. In . a well-known experiment done by one of Rutherford's students, . alpha particles were observed to scatter backwards from a gold foil. Rutherford’s . nucleus is present in all eukaryotic cells and surrounded by a nuclear membrane . .This organelle has two major functions: . it stores the cell's hereditary material(DNA) . and . it coordinates the cell's activities,. Dr. Mamoun Ahram. Faculty of Medicine. Second year, Second semester, 2014-2014. Structure and function of a nucleus. A repository of genetic information. The nuclear membrane, known as the nuclear envelope, adds an additional level of gene regulation post-. . . For elements of higher atomic number, the ratio rises to approximately 1.6 to 1 . As a nuclide departs from this stable ratio, changes in the nucleus occur which tend to bring the product to a more stable arrangement. .
