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.
Answer: a) HIV is a retrovirus overtaking living cells to duplicate itself. Explanation: HIV is a retrovirus, a virus that overtakes the biosynthesis of living cells to duplicate itself. HIV invades a normal cell and uses that cell's biomechanisms to reproduce new HIV cells. The terms HIV and AIDS are not synonymous. HIV is the virus responsible for causing AIDS, but the person who is HIV positive does not automatically have AIDS. HIV is not curable, it is only treatable. The nurse is caring for a client undergoing testing for HIV.
