Biosphere: The earth
Ecosystem: Forest in Madagascar
Community: All organisms in the forest
Population: Group of one species in the forest
Organism: 1 member within a population
Describe and provide an example of each level of
Organ system: Nervous system
biological hierarchy, in order
Organ: Brain
Tissue: Nervous tissue
Cell: Nerve cell (alive, lowest level that can perform all activities required for life
Organelle: nucleus (not alive)
Molecule: DNA
Multi-drug resistant TB, Russia's prisons are perfect. reeding ground
Review the video and explain a real life
Genetic Diversity allows some bacteria to be resistant while others aren't
explanation of why evolution matters now
The immune bacteria multiply until all bacteria is resistant
When you introduce antibiotics to a population of bacteria, you kill all bacteria not-resistant.
However, the resistant bacteria are not killed, reproduce, and transfer its resistance to its
offspring
Explain how evolution occurs in a population of
bacteria exposed to antibiotics
the agent of natural selection in this case is the antibiotic
Environments that contain antibiotics will favor resistant strains of bacteria
Most used in livestock, then humans
What are the primary contributors to antibiotic
resistance in our environment
Slight use in aquaculture, pets, and crops
