Cancer Epidemiology Cancer is not a single disease; it is a myriad or collection of diseases with many different manifestations as there are many different types of tissues and cell types Cancer is a disease of abnormal gene expression. Cells are constantly evolving and have the natural selection pressures to change Common biological properties of tumor cells: 1) Deregulated clonal cell growth- all cells in a tumor originated from one single cell that acquired mutations that made it deregulated

like E. coli and samonella poisoning. Parasitism-An example of parasitism is between Pearl fish and Sea Cucumber. The Pearl fish live in the Sea Cucumber’s cloaca which they enter through the anus. The Pearl fish then breaks through the respiratory membrane and situates its home. Commensalism- Commensalism is a situation in which two organisms are associated in a relationship in which one benefits from the relationship and the other is not affected much. The two animals are called commensals. This

Fundamental of Cell Biology A cell is the basic unit of life‚ and all organisms are made up of one or many cells. One of the things that all cells have in common is a plasma membrane‚ it is also called as cell membrane as it is works as a barrier between the inner and outer surface of a cell. In animal cells‚ the plasma membrane is present in the outer most layer of the cell and in plant cell it is present just beneath the cell wall. It separates the contents of the cell from its outside environment

Iso osmolar can be known as the point in which the substance of experimentation faces no change despite the amount of solute inside the solvent( because the solvent and solute concentration is equal. This is where the line on a graph would cross on the

Introduction Last week‚ my Biology class and I went down to the Port Kembla Rock Platform. While we were there we surveyed five different sectors about the rock platform and recorded them‚ these included: 1. Surveying the abiotic characteristics of the rock platform 2. Observing the abundance and distribution of the Black Periwinkle (Nerita Atramentosa) 3. Observing the feeding relationships and food webs of the organisms 4. Finding the adaption’s of organisms 5. And Observing the human impacts

The article “Biology is Beauty” by Geoffrey Cowley touches on the aspects behind beauty. The article states that everyone shares a sense of what is attractive. Basically‚ Cowley is stating that people are attracted to what is on the outside‚ even if we do not know it. Even though points of attraction can vary over societies‚ beauty is an innate quality we all think of. The article touches on a few examples that the author feels explains. First‚ Cowley says that humans love symmetry; people prefer
