Question 1: According to the lesson, which taxonomic rank contains the greatest number of different kinds of organisms and why?
Phylum
Question 2: In the hierarchy domain → species, which rank did the presenter describe as indicating organisms most closely related to one another?
Genus
Question 3: The lesson contrasted eukaryotes and prokaryotes. Which statement matches the video’s summary of their evolutionary relationship?
Eukaryotes evolved from prokaryotes
Question 4: When describing viruses the video used a rocket-ship analogy for infection cycles. Which cycle results in immediate lysis of the host cell and rapid virion release?
Lytic cycle
Question 5: How did the video contrast the lysogenic cycle with the lytic cycle in terms of viral genome propagation?
Lysogenic integrates and replicates with host DNA during cell division
Question 6: Which explanation from the video best describes why vaccines work?
Vaccines expose the immune system to an inactivated form so it produces antibodies
Question 7: In the review of Kingdom Protista, which trophic modes were associated with the three broad protist categories in the video?
Animal-like are heterotrophs, plant-like are autotrophs, fungus-like are decomposers/parasites
Question 8: The fungi lesson listed four phyla. Which phylum did the presenter link to sac-like spores and an example like yeast?
Ascomycota
Question 9: From the bacteria/archaea comparison, which trait did the speaker emphasize as shared by both groups?
Both are unicellular prokaryotes
Question 10: In the plant unit, what core distinction did the lesson use to separate major plant phyla?
Spore-producing versus seed-producing
Question 11: Which reproductive strategies for plants did the video list as sexual and asexual dispersal methods?
Sexual via pollination and seed dispersal by animals/wind/water; asexual via vegetative propagation
Question 12: When discussing Animalia, which phylum group did the speaker identify as containing vertebrates like mammals and birds?
Chordata
Question 13: The presenter categorized worm phyla. Which grouping was matched with segmented bodies in the video?
Annelida (segmented worms)
Question 14: Applied scenario: you discover an organism with club-shaped fruiting bodies forming dome-like mushrooms. Based on the review, which fungal phylum is the best initial classification?
Basidiomycota
Question 15: Concept application: a prokaryotic organism dies in oxygen-rich conditions. Which term from the review best describes its oxygen requirement?
Obligate anaerobe
