Q: What is the least shared characteristic in the table?
A: Placenta

Q: What is the evolutionary order from most recent to most ancient?
A: Human → Kangaroo → Lizard → Frog → Salmon

🔹 Domains of Life

Q: What are the three domains of life?
A: Bacteria, Archaea, Eukarya

Q: What do Eukarya and Archaea have in common?
A: No peptidoglycan in cell walls, same response to penicillin, use RNA polymerase

Q: What do Bacteria and Archaea have in common?
A: No membrane-bound organelles and circular DNA

🔹 Domain Trait Comparison (Table 24.2)

Q: Which domains have a nuclear envelope?
A: Only Eukarya

Q: Which domains have membrane-bound organelles?
A: Only Eukarya

Q: Which domains have peptidoglycan in cell walls?
A: Only Bacteria

Q: Which domains have RNA polymerase?
A: All three, but Archaea and Eukarya have several kinds, Bacteria has one kind

Q: Which domains use methionine as the first amino acid in protein synthesis?
A: Archaea and Eukarya

Q: Which domains have introns in genes?
A: Eukarya and some Archaea

Q: How do the domains respond to antibiotics like streptomycin and chloramphenicol?
A: Bacteria – growth inhibited; Archaea & Eukarya – not inhibited

Q: Which domains have circular chromosomes?
A: Bacteria and Archaea

Q: Which domains can grow at temperatures >100°C?
A: Some Archaea

🔹 Dichotomous Key (Plant Phyla)

Q: How do you identify plant groups using the dichotomous key?
A:

1. a. Vascular tissue → Go to 2
     b. No vascular tissue → Bryophyta

2. a. Seeds → Go to 3
     b. No seeds → Filicinophyta

3. a. No flowers → Coniferophyta
     b. Flowers → Angiospermophyta

Q: Which plant has no vascular tissue?
A: Bryophyta

Q: Which plant has vascular tissue but no seeds?
A: Filicinophyta

Q: Which plant has vascular tissue, seeds, but no flowers?
A: Coniferophyta

Q: Which plant has vascular tissue, seeds, and flowers?
A: Angiospermophyta

🔹 Taxonomy Basics

Q: What are the 8 taxonomic ranks in order?
A: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

Q: What is the mnemonic for taxonomic ranks?
A: Did King Philip Come Over For Good Spaghetti?

Q: What are the genus and species in Homo sapiens?
A: Genus = Homo, Species = sapiens

🔹 Cladograms & Evolution

Q: What does a cladogram show?
A: Divergent evolution of organisms

Q: What is a clade?
A: A group of organisms with a single common ancestor and all its descendants

Q: What do species with similar genes/proteins likely share?
A: A recent common ancestor
