(original population) differences within the species.
Environmental changes:
Species with favorable traits (naturally selected for):
Species selected against:
New population:

48. Bacteria and Viruses Microbe Bacteria Viruses Size Larger Very small
Cell Type
Prokaryotic: has plasma membrane, DNA, ribosomes
No cell
DNA or RNA surrounded by protein
Treatment
Antibiotics
Anti-Viral, vaccines
Alive
Living
NOT Living
Examples
Streptococcus (Strep)
Flu. HIV, Small pox

51. Important Definitions
Disease - any change from a state of health
Infection - invasion of the body by a pathogenic microorganism
Pathogen - disease causing agent
Virus - particle of nucleic acid, protein, and in some cases lipids
Antibiotic - chemical that stops the growth and reproduction of bacteria

52. Important Definitions
Antigen – substance that triggers an immune response
Bacteria – singe-celled microscopic organism that is capable of rapid reproduction
Immunization – use of vaccines to protect from pathogens
Vaccine – stimulated the production of antibodies; injection or oral

53. Immune Response to Pathogens (Viruses and Bacteria)
Active Immunity – response of the immune system when exposed to an Antigen (pathogens that trigger an Immune response) Ex: Vaccination
Antibodies – Proteins that fight disease
B Cells – make antibodies and memory cells
Memory Cells – stores antibodies produced from initial exposure to disease
T Cells – help B Cells and kill infected cells

54. Immune Response to Diseases (Viruses and Bacteria)
Passive Immunity – Antibodies from another organism are injected into the blood stream (Ex: Breast Feeding)
Skin provides the first line of defense

55. Complete the chart above.
Distinguish between active and passive immunity.
