Heart Disease Heart attacks are the leading cause of death and illness in the United States. At the root of the cause for heart attacks is a disease called âarteriosclerosis,â which is the accumulation of âplaqueâ or âcrudâ (cholesterol, fatty deposits, and other substances) on the inner lining of artery walls.
Budding is a form of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site.The new organism remains attached as it grows, separating from the parent organism only when it is mature, leaving behind scar tissue.ince the reproduction is asexual, the newly created organism is a clone and is genetically identical to the parent organism. Organisms such as hydra use regenerative cells for reproduction in the process of budding.
Many species are unicellular and reproduce asexually by budding (Fig. 2, 4)or fission (Fig. 3, 7). The process of budding begins in a mature yeast cell at predetermined areas of its cell wall.igure 3: Asexual reproduction of a fission yeast. Mitosis of the nucleus occurs, followed by elongation of the cell and formation of a cell wall that divides the cell in half, separating the two nuclei. We will describe the life cycle examples of a budding and a fission yeast.
