14. 1.2 The Classification of Living Things

15. 1.2 The Classification of Living Things
Living organisms are assigned to groups based upon their similarities.

16. 1.2 The Classification of Living Things
Living organisms are assigned to groups based upon their similarities.
Systematics is the discipline of indentifying and classifying organisms.

17. Domains

18. Domains
Domains are the largest classification category.

19. Domains Domains are the largest classification category.
Biologists assign organisms to one of three domains based on biochemical and genetic evidence.

20. Domain Archaea
Archaea are single- celled organisms that lack a membrane-bound nucleus.
Archaea can be found in environments that are too hostile for other life forms.

21. Species of the domain Archaea are not inhibited by antibiotics
Domain Archaea is mostly composed of cells that live in extreme environments.
Species of the domain Archaea are not inhibited by antibiotics
here are three main groups of Archaea: extreme halophiles, methanogens, and hyperthermophiles
Halophiles are organisms that live in high salt concentrations. Methanogens produce methane and can life in the human gut, hyperthermophiles can live at temperatures above 70C.

22. Domain Bacteria
Bacteria are single- celled organisms that lack a membrane-bound nucleus.
Bacteria are found almost everywhere on the planet Earth.

23. Domain Eukarya
The cells of all eukaryotes have a membrane-bound nucleus. Members of the Domain Eukarya are further categorized into one of four Kingdoms.

47. The Human Species
Humans depend on healthy ecosystems for our own survival.

48. The Human Species
Humans depend on healthy ecosystems for our own survival.
The human species modifies ecosystems for own purposes.

49. The Human Species
Humans depend on healthy ecosystems for our own survival.
The human species modifies ecosystems for own purposes.
Preservation of ecosystems is important to ensure our continued existence.
