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

This is the familiar kind of battery which has a fixed amount of energy stored in it during manufacture‚ and once that energy has been used up the battery is simply thrown away and replaced. There are many different types of primary battery now available

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

Evolution of Sickle Cell Sickle Cell was discovered in the United states although it originated in Africa . The sickle cell disease (SCD) describes traits of an inherited red blood cell disorder‚ having SCD means you have abnormal hemoglobin‚ called hemoglobin S or sickle hemoglobin‚ in your red blood cells.

Processes used to produce transgenic species Transgenic species are groups of organisms that contain genes from other species. Transgenic animal species are produced by two main methods: the transgene ("two separately cloned genes are spliced together‚ one gene contains the coding sequence for the protein of interest and the other controls the tissue in which the animal protein will be expressed") can be microinjected in or created by using embryonic stem cells. The microinjection method involves
