Stem cells are originally defined in the haematological system, but recently have been found in a multitude of other sites. These cells all share the same features of self-renewal and multipotentiality and different types and therapeutic strategies have been defined with respect to the nervous system. There are three known …

Question 1: Many companies are now embracing target marketing to compete more effectively in the market place. According to Kotler and Keller, (2006:240) “instead of scattering their marketing effort (a ‘shotgun approach’, they should focus on those consumers they have the greatest chance of satisfying (a ‘rifle’ approach).

Research Question: To investigate how different temperatures affect the beetroot pigment and finding out the absorbance and transmittance % using a visible spectrophotometer. Background Information: Beetroots contain betalains which are the red pigments present in the cell vacuole. Betalains are soluble in water and they contain nitrogen. Betalains extracted from …

Robert Hooke(1665): Published first book on cells. Discovered cells when looking at cork under a microscope. Discovered cell structure of plants. Anton von Leewenhoek (1650-1700):Dutch. First observed protists. With a simple lens(x200), he observed unicellular organisms & nuclei. By using his ability to grind lenses, he greatly improved the microscope …

Protists are defined as unicellular, or single-celled, eukaryotic organisms. However, some protists are multicellular. Many protists live individually, but some are …

The human embryo is a collection of clusters of non-specific cells, which then develop into the tissues of the adult human. In particular immature, non-specific neuroblasts must be differentiated into the highly specialised cells of the nervous system, each with a unique structure, function and synaptic interactions (Whatson 2004). The …
