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

structure of a cell to is a car. The reason I choose to do a car is because it is very similar to the structure of a cell and because to me it was the most interesting choice to choose from. Another reason I choose to compare the cell to a car is because it seemed to be the easiest one for me to do as compared to a Hogwarts or a city. Doing a house or a prison would have also been fairly easy but they were already picked by the people at my table. That wars why I choose to compare the human cell to an automobile

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

Noah Onoff Dr. Ho Intro to Plant Life 10 December 2012 The Evolution of Carnivorous Plants In addition to being a subject in the occasional Hollywood horror movie‚ carnivorous plants are possibly the most fantastic members of the plant world. Over time‚ they have developed unique morphological characteristics in order to survive‚ paying homage to Darwin’s theory of natural selection. How carnivorous plants evolved is still somewhat unknown to botanists‚ this‚ in addition to their morphology

For this project I will be planting a Palo Verde tree in the front yard of my house on September 12. I will need to find a nice spot to plant the tree to make sure it won’t die. I’m choosing to plant a tree because I’ve always wanted to do it. I’m going to plant the tree with soil to give it the nutrients it needs. Also I am going to put wood chip mulch all around it to keep it from drying out from all the heat. I will water the tree every day‚ and check for growth every other week. Planting

STUDY GUIDE INTEGRATED SCIENCE 10 PLANT UNIT DO YOU/CAN YOU…. 1. Understand that both plants and animals (eukaryotes) undergo a similar process for cellular division/reproduction? Both plant and animal cells undergo mitosis and meiosis. In plants‚ there is an alternation of generations; the gametophyte generation‚ where haploid gametes (pollen and ovule; sperm and egg) are produced via mitosis. Then the sporophyte generation combines these two into spores via meiosis‚ resulting in a diploid

1. The problem that is being tested by the researchers in this study is the effects of a low fat‚ plant based diet on participants in a multi-center corporation. More than half of Americans today are either overweight or obese and have an increased risk of type 2 diabetes‚ cardiovascular disease‚ hypertension and some cancers. The researchers wanted to test how a plant based diet will affect these factors in people in the workplace. They chose the work place because it is a place that people spend
