  1. Biology Standard 10d Work in Progress

  2. Bio Standard 10 d Bacteria Viruses both 1-have metabolism 1-lack metabolism DNA/RNA 2- grow 2-No growth pathogens 3-reproduce by mitosis 3-Need host cell to replicate Some can kill you if untreated 4-Ex.: HIV, herpes 4-Ex.: streptococcus E-coli infectious 5-not alive nor dead 5-are alive (cell) 6-sub-microscopic Different shapes 6-microscopic 7-not curable 7-curable with antibiotics 8-vaccines may prevent infection 8-some are needed to sustain life

  3. Compare & Contrast Bacteria & Viruses 1 1 No metabolism metabolism 2 2 3 3 Bacteria Viruses 4 4 5 5 Ref.: bio standard 10d Double Bubble-Compare & Contrast

  4. Compare & Contrast Bacteria & Viruses 1 1 lack metabolism, enzymes, and growth microscopic Metabolism, enzymes, growth 2 2 It is a cell It is not a cell. pathogen 3 3 Bacteria Needs host’s energy to reproduce Replicates by mitosis or simple cell division Viruses DNA 4 4 lacks ribosomes Has ribosomes; Can kill you if not treated Not alive and not dead Yes, it is alive. 5 5 Ref.: bio standard 10d Double Bubble-Compare & Contrast

  9. Circle Map Central Bio st. 10e HIV transmission White blood cells targeted Health class Blood transfusion Bodily fluids Full blown AIDS ineffective immune system HIV Testing Reduced life span Unprotected sex HIV (Human Immunodeficiency Virus) Sharing of needles Thief Destruction of helper T-cells Retroviral drugs Stop viral reproduction Reduced white blood cell count Lowered t-cell count Opportunistic diseases Contaminated mother milk Pneumonia, eye infections, body sores USC Kids Death by opportunistic infection experience 11 Bio books pg. 933-935

  11. HIV / AIDS Full Blown AIDS Holt Biology pgs. 934-935

  12. HIV Virus Invades T-cell cannot kill pathogens T-Cell T-cell dies HIV Virus reproduces and bursts out of cell and moves into another T-cell Lowered T-cell count Opportunist infections kill person Weakened Immune system Full blown AIDS T-cell count <200 / Ml of blood

  13. Flow Map from HIV Infection to Death Bio st. 10e CJH Bio book pgs. 928-929 Enters white blood cells by binding to CD4-protein on some human cells HIV enters the body HIV enters T-cells HIV reproduces HIV bursts out of T-cell & kills it One less T-cell to kill pathogens Reduced T-cell count Fewer T-cells kill fewer pathogens Even lowered T-cell count T-cell count < 200 / ml of blood Immune is system incapacitated Full blown AIDS Opportunistic diseases infect the AIDS victim and kill him/her
