During WWII & the reign of Hitler was the Auschwitz Concentration Camp‚ a labor camp‚ which could be considered to be one of the worst places for a person of the Jewish faith place to be at that time in history. Handed down through history‚ it is considered to be one of the brutalist places on earth that a person could be. As James Deem described it‚ “Prisoners receiving punishment were often placed in cramped basement cells and deprived of food” (9). To be put into simple terms‚ it was torture.

characteristics of a healthy cell and a cancer cell is very different. Healthy cells stop reproducing when there are enough cells‚ however‚ cancer cells continue to reproduce. Due to this continued growth a tumor‚ which is a cluster of cancer cells‚ is formed. Cancer cells do not interact with other cells like the healthy cells. Healthy cells stop growing when they hear signals from the nearby cells‚ in contrast‚ cancer cells do not respond to these signals. When healthy cells get old or damaged they

carry out all of our activities. Cells in our bodies need glucose to respire and in the process release the energy we need. Glucose is also a type of carbohydrate. It has a chemical formula of C6H12O6 and is a monosaccharide reducing sugar (Kolej Mara Banting – Students’ Handbook for Biology HL Year 1). It is the simplest form of carbohydrate. In this experiment‚ sulphuric acid‚ H2SO4 and potassium permanganate‚ KMnO4 is added into glucose with different concentration and the time taken for the purple

a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

though a cell is the basic unit of an organism it can be pretty complex inside of one. So why don’t we try and make it a little simpler by comparing it to something we’re all more comfortable with? Take Disneyland for example! Everyone is familiar with Disneyland and how it works. Let’s see just how similar these two can be. First‚ would be the entrance gate. The entrance gate could be our cytoplasm. Cytoplasm is the jelly-like fluid that fills a cell and inside is all the other cell organelles

allow cell phones to be sold without pre-market testing. The rationale‚ known as the “low power exclusion‚” distinguished cell phones from dangerous microwave ovens based on the amount of power used to push the microwaves. At that time‚ the only health effect seen from microwaves involved high power strong enough to heat human tissue. The pressure worked‚ and cell phones were exempted from any type of regulatory oversight‚ an exemption that continues today. An eager public grabbed up the cell phones

Cell Fusion Introduction: The fusion of cells is a fundamental biological event that is essential for a variety of developmental and homeostatic processes. The importance of cell-cell fusion during development and disease is displayed in a variety of biological processes including‚ but not limited to‚ fertilization‚ development of tissues‚ the immune response‚ and aspects of tissue regeneration due to stem cells (Chen and Olson‚ 2005). Fertilization‚ which is the fusion of sperm and egg‚

The cells of the adaptive immune system are special types of leukocytes‚ called lymphocytes. There are two main types of lymphocytes‚ B cells and T cells‚ which are derived from hematopoietic stem cells in the bone marrow. T cells are involved in cell-mediated immune response‚ whereas B cells are involved in the humoral immune response. The surface of each lymphatic cell has receptors that enable them to recognize foreign substances. There are two major subtypes of T cells: the helper T cell and

Cells do everything from providing structure and stability to providing energy and a means of reproduction for an organism. There are many professions that have jobs like the organelles in a cell. One example is a Prison. A prison is a clear representation of a cell because all the organelles have a function that is tantamount to a prison. Also it is logical because each function have a function that relates to the jobs found in a prison. The Nucleus in a cell controls everything in the cell

Abstract: The main objective of this Lab‚ is to experiment with stoichiometric measurements‚ since it is one of the most important subjects in chemistry. In addition‚ stoichiometric measurement is widely used in chemistry‚ because it indicates the proportion of mass in which various substances react. By examining one specific example of stoichiometric determination‚ which is: “Stoichiometry and limiting reacting”‚ we found out the different mass proportions in which substance react. In this case
