This week you will start the tree with the three clades: Bacteria, Archaea, and Eukarya. Add the following traits to the tree where they appear:
ester bonds in cell membranes
ether bonds in cell membranes
presence of membrane-bound nucleus
presence of membrane-bound organelles
presence of histones
DNA as genetic storage
presence of peptidoglycan in cell wall
Include the following species under the correct clade:
- american black bear
- Escherichia coli
-Methanobrevibacter smithii

Classify each description according to whether it describes
bacteria, archaea, or eukarya.
None associated with human disease Some have cell walls with lipopolysaccharide Perform photosynthesis with unique pigments Contain double stranded DNA within a membrane bound nucleus Contain membrane bound organelles Some are methanogenic Cause diseases in humans Unique lipids in the plasma membrane Thermoacidophiles Cell walls contain peptidoglycan Archaea Bacteria Eukarya

complete the boxes with yes or no depending on the answer. Characteristic Bacteria Archaea Eukarya Is a nucleus present? (yes or no) Does it contain DNA? (yes or no) Are membrane-bound organelles present? Is the domain primarily unicellular or multicellular? Is there sexual reproduction via meiosis? Is a plasma membrane present? If so, describe it. Is there a cell wall in some of the members?

Metabolic lipids ribosomal thermophiles halophiles transfer Bacteria Eukarya Archaea peptidoglycan Drag the text blocks below into their correct order. Archaea also possess adaptations to their metabolic pathways that allow them to live in extreme environments, such as areas with high levels of salt (_____________) or high temperatures (___________). Although they share many bacterial characteristics, members of the Domain Archaea are more closely related to Domain ____________ than to bacteria. Characteristics that define archaea, however, include the presence of a cell...

Some help is appreciated, thanks!!
Use the features listed below to design a presence/absence character matrix for the three domains just as you did for your traits in Lab 1. You need to reword the features column from Table 1-1 into a feature that can be quantified as present (1) or absent (0) in Table 1-2. See line 1 in Table 1-2 as an example. (3.5 pts.) 1. Table 1-1. Features of the 3 domains of life Table 1-2. Character...
