Factual Evidence‚ examples‚ statistics‚ expert opinions‚ and images are the different categories of support that Rottenberg and Winchell outlined in chapter 6. In my view‚ factual evidence and statistics are more convincing because those are something that can’t be made up and it is always available to be researched on the Internet. But giving examples‚ including expert opinions‚ and showing images are also vital part of a strong argumentative writing. Beau Watts focused on supporting the stem cell

Barbara Hagemeister Mrs. Hall Comp I April 26‚ 2011 Is Stem Cell Research Good or Bad? Stem cell research is a very complex subject. “Stem cells hold great potential for developing therapies to treat a wide range of human diseases. Already in clinical use is blood stem cell transplant‚ known well as bone marrow transplant therapy for the treatment of patients with certain types of blood diseases and cancers. The discovery of stem cells in various adult tissues‚ stem cells plasticity‚ and human

Teratogensis: Caudal Dysgenesis ( sirenomelia) The third week of development is the period of greatest sensitivity for teratogensis (Sadler 2010). In caudal dysgenesis (sirenomelia) genetic abnormalities and toxins disrupt normal gastrulation. A more common name for sirenomelia is the mermaid syndrome. Sirenomelia is characterized by insufficient mesoderm formed in the caudalmost region of the embryo. The mesoderm contributes to the formation of the lower limbs‚ urogenital system and the lumbosacral

The human body shows its ability to heal itself when injured. However‚ the human body is not the only living thing that has a way of healing with no help. Planaria‚ which are free-living flatworms‚ are known for their quick regeneration from a fraction of the body. Scientists have been studying planaria and the effects of magnetism on the regeneration rate of the planaria. The hypothesis of this experiment is that if the planarians are exposed to a certain number of magnets at a closer distance‚

Stem cells are cells in living organisms are able to adapt to become specialized cell types. They can split apart and regenerate‚ which is an incredibly useful mechanism in our bodies because it allows us to grow and heal. Stem cell research has allowed medical breakthroughs to fight malignant and nonmalignant diseases and ailments. Stem cells are able to create tissue and organs. By researching stem cells‚ we can continue use them to our advantage. They prove very beneficial in treating medical

English Section 1 Stem Cell Research Term Paper Stem Cells are undifferentiated cells. This means that they can divide and multiply before given a specialized job in the body such as bone cells or skin cells. There are embryonic stem cells‚ which come from developing embryos‚ somatic stem cells‚ which come from adults‚ and umbilical stem cells‚ which come from the umbilical blood. (Stem Cell Basics‚ 2) Although each of these stem cells can all be used to treat a variety of different diseases

Hans Spemann and Hilde Mangold: Primary Embryonic Induction The most spectacular transplantation experiments were published by Hans Spemann and Hilde Mangold in 1924.* They showed that‚ of all the tissues in the early gastrula‚ only one has its fate determined. This self-differentiating tissue is the dorsal lip of the blastopore‚ the tissue derived from the gray crescent cytoplasm. When this dorsal lip tissue was transplanted into the presumptive belly skin region of another gastrula‚ it not only
