Short End of the Gene Pool In the article‚ “My Inner Shrimp”‚ by author‚ Garry Trudeau‚ he goes into detail about the early years of his ‘short’ life and how they continue to emotionally impact him well after the issue is no more. Everyone has been singled out for one reason or another at least once in their life which makes it easy to understand where Trudeau is coming from. After reading this article‚ one might think that Trudeau simply needs tougher skin. It’s been known that kids can be cruel

Cell Specialisation All cells are designed to perform a particular job within an organism‚ that is‚ to sustain life. Cells can become specialized to perform a particular function within an organism‚ usually as part of a larger tissue consisting of many of the same cells working together for example muscle cells. The cells combine together for a common purpose. All organisms will contain specialised cells. There are hundreds of types of specialised cells. Below is listed some of the major ones

CHAPTER 12- THE CELL CYCLE I. Concept 12.1- Cell division results in genetically identical daughter cells A. Overview 1) The continuity of life is based on the reproduction of cells or cell division. 2) The cell division process is an integral part of the cell cycle‚ the life of a cell from the time it is first formed from a dividing parent cell until its own division into two cells. B. Cellular Organization of the Genetic Material 1) A cell’s endowment of DNA‚ its genetic

Animal Cells Vs. Plant Cells There are quite a few similarities and differences between plant and animal cells. Whether it be the internal parts of the cells‚ or the processes they go through. They also have differences in shape and sometimes size. These are only a few examples of similarities and differences between the two different cells. To begin with‚ both animal and plant cells are eukaryotic cells. This means that both cells have the same internal features‚ such as a cell membrane‚ a

Cell Structure - Cell Organelles 1. What is cell theory? Cell theory asserts that the cell is the constituent unit of living beings. Before the discovery of the cell‚ it was not recognized that living beings were made of building blocks like cells. The cell theory is one of the basic theories of Biology. 2. Are there living beings without cells? Viruses are considered the only living beings that do not have cells. Viruses are constituted by genetic material (DNA or RNA) enwrapped by a protein

increase in size as their cells grow and divide. Almost all cells complete a full cell cycle that includes interphase and cell division. In interphase‚ cells serve their specialized functions‚ grow‚ and copy their genetic material. Mitosis is the first stage of cell division‚ in which the copied chromosomes are separated into two new nuclei. Then in cytokinesis the cell divides into two daughter cells. If no mutations or errors occur‚ the genetic material in each daughter cell is identical to what was

structure of these cells is a flying disk shaped like a donut‚ this is so maximum haemoglobin can be carried allowing maximum amount of oxygen to be transported. Sperm cells A sperm cell is the male reproductive cell that carries the male portion of chromosomes and deoxyribonucleic acid (DNA) information to be fused with the female egg or ovum. The sperm cell carries various amount of heredity information inside the cell nucleus. There are various ways in which sperm can be transmitted to the
