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.
Some of the immune cells in a person living with HIV are already infected with HIV, therefore the inflammatory response brings more HIV (contained in the infected immune cells) to the site of the STI in the genitals or rectum. Consequently, more HIV enters the body fluids in that area. For example, a vaginal STI increases the amount of the virus (viral load) in the vaginal fluid. Research shows that the more virus there is in the body fluids of a person living with HIV the higher the risk of passing HIV to someone else. 3 HIV also replicates, or makes more HIV, quicker in immune cells that have been âactivatedâ through inflammation, compared to immune cells that are not âactivated.â
