5. The Rh factor The Rh factor types were discovered in 1940 by alexander wiener and Karl Landsteiner . Rh blood group is the most complex genetic of all blood type system, because it hooks 45 different surface antigen on the surface of the red cells that are controlled by two closely linked genes on chromosome 1. The antiserum for blood sample was the outcome results of the research that was done on the rhesus monkeys which lead to the naming of the Rh system. (Oneil, 31-07-2015) The RH factor…

typical eukaryotic cell. A typical human cell contains hundreds of lysosomes but can be found in much higher quantities in cells more directly involved in exocytosis and cells of the immune system. Under a microscope, lysosomes can be observed as spherical-shaped, tiny membranous sacs composed of a single phospholipid bilayer that separates the acidic interior (pH 4.8-5) from the rest of the cell. The acidity is maintained by the continuous pumping of hydrogen ions into the cell, allowing for…

A new and highly talked about topic is stem cell research. Stem cell research is an extraordinary, yet very controversial subject. Stem cells are a very large focus in today’s study of biomedical research. Stem cell research is beneficial because the research that is done can help cure diseases and regenerate cells that will be able to give humans, and their body’s, another chance at being healthy. Stem cells are defined as, “Undifferentiated cells of a multicellular organism that are…

identify concepts on cells and to learn more about the functions and reproduction of cells within living organisms. Lab Summary: While doing this activity we experimented with bacterial growth and I was able to witness growth in its replication. Through the process of mitosis, I was able to view cellular reproduction. Lab Answers A. Bacterial growth observation. The population doubling time is estimated to be 20 minute. B. Cellular reproduction : The three types of cell separation are…

examined in detail in this essay. The mechanisms of this pathway, the impact of Shh on cell fate and the genetic regulation events that occur as a result will be explored. . . . . . . . . . .…

transferring yeast cells onto YPD and SD plates over a period of 24-72 hours in a thirty degrees Celsius incubator, in return will grow yeast. Introduction Yeast can reproduce both asexually and sexually, which makes it very easy to grow in the laboratory, as it is very small in size. Mutant yeast can be easily isolated considering yeast consists of a single cell and can be grown as a haploid or diploid. Diploid cells are formed by the combination of MATa and MAT alpha cells. However, under…

The mitochondria is one of the most interesting components of the eukaryotic cell. Endosymbiosis is the term modern scientists use for how the mitochondria came to be. Symbiosis translates from Greek to English as “living” “together.” Constrantin Mereschkowsky, known as the founding father of the theory of endosymbiosis, was one of people who started the concept of endosymbiosis, although he had called it “symbiogenesis,” defining it as: “the origin of organisms through the combination and…

Comparing and Discovering the Properties of Animal and Plant Cells INTRODUCTION: Scientists have developed classification units among livings. One of this classification types is kingdoms. It represents widely covered societies, including Animalia and Plantae. It is known that all livings are composed of cells, from the cell theory, so animals and plants also have a cell association. The cellular structures of animal and plants cells are clearly different. These structural differences will be…

results between the two models. Each animal’s immune system is different and works in its own way according to its biological model. The comparasins of the model gives little or no help to the benefits of research ( Cynthia, 33). For example, a certain type of primate is not affected by the HIV virus, but the human’s immune system gets destroyed overtime by the same virus. There is only a slight difference between the models. Each animal has its own unique reaction to its own environment and…

reproduction is a type of reproduction in which two different cells combine, which create an offspring. When two cells called the egg for female, and sperm for male, combine and join together they create a new organism called a zygote. During meiosis, one diploid cell divides and makes four haploid sex cells. Meiosis has two divisions of the cytoplasm and the nucleus, the divisions are called Meiosis I and Meiosis II. Reproductive cells go through interphase before meiosis. “ A reproductive…
