Where NA = 6.022 x 1023. In above glucose sample, the no. of glucose molecules = 0.01 x 6.022 x 1023 = 6.022 x 1021. Remember that one mole of any substance contains Avogadro number of particles (may be atoms or molecules or ions etc.). If the substance is molecular, the number molecules will be equal to 6.022 x 1023.
The science behind the virus and the HIV life cycle help put wider prevention, treatment, and general HIV awareness into context. The immune system and HIV. The HIV virus attacks a type of white blood cell called T-helper cells (also called CD4 cells). These cells are important when it comes to having a healthy immune system as they help us fight off diseases and infections. HIV cannot grow or reproduce on its own. Instead, it makes new copies of itself inside T-helper cells.
The Human Immunodeficiency Virus (HIV) seems to only infect the CD4 (or T-helper) cells of the immune system.The CD4 cells are responsible for activating and directing other â¦ immune system cells.  HIV also infects macrophages and microglial cells that express the CD4 molecule on their surface.The virus can also infect a subtype of myeloid dendritic cells MDC-1. 12 people found this useful.he Human Immunodeficiency Virus (HIV) seems to only infect the CD4 (or T-helper) cells of the immune system.
