You can figure this out. Determine the molecular weight of glucose- that is the weight in grams of 6.02x10^23 molecules (one mole of glucose). Then weigh one sugar cube- that is the weight of your unknown number of molecules. Divide your sugar cube weight by the molecular weight- that gives you the percentage of a mole that your sugar cube contains.
HIV is the cause of the spectrum of disease known as HIV/AIDS. HIV is a retrovirus that primarily infects components of the human immune system such as CD4 + T cells, macrophages and dendritic cells. It directly and indirectly destroys CD4 + T cells.
(These cells are also called CD4-positive lymphocytes because HIV uses the protein CD4, present on the surface of the cell, to attach itself and pry its way into the cell.) Each day, your body produces millions of CD4+ T-cells to help maintain your immunity and fight off invading viruses and germs.uman immunodeficiency virus (HIV) infects the cells of the immune system. In particular, HIV attacks and destroys the T helper lymphocytes, or T-cells, which are crucial to the immune system and immune response.
