Learning about Cells. First thing I want to show you is two beautiful pictures of a Cell. Imagine all of this is in something so small we cannot see it with our naked eyes. About 10‚000 average-sized human cells can fit on the head of a pin. There are a few exceptions‚ but the average cell is very tiny. Here are a few beautiful examples of a cell structure to kind of give you an idea of its beauty‚ and how they fit together. Plasma Membrane (cell membrane) First we are going to learn about

How would you account for changes in political cleavage structures and how does this impact on party systems? The fundamental nature of this essay is to look at the different explanations of the emergence and development of political cleavage structures and its impact on party systems in Western Europe. The party systems of the Western European states reflect both common lines of development of Western European history and country-specific characteristics of the progress of state and nation

Comparison of Plant and Animal Cells Introduction Eukaryotic cells are very complex; there are many organelles‚ each serving a distinct function‚ present in eukaryotic cells. We can divide the eukaryotic group of cells in to two main groups‚ according to the presence of these membrane bound organelles‚ and the structural differences amongst the cells and their organelles. The two groups of eukaryotic cells are plant and animal cells. Nucleus The reason that plant and animal cells are not divided

basis for biological inheritance. The process starts when one double-stranded DNA molecule produces two identical copies of the molecule. The cell cycle (mitosis) also pertains to the DNA replication/reproduction process. The cell cycle includes interphase‚ prophase‚ metaphase‚ anaphase‚ and telophase. Each strand of the original double-stranded DNA molecule serves as template for the production of the complementary strand‚ a process referred to as semiconservative replication.
