Step by step
Solved in 2 steps
- What phylogenetic and physiological evidence suggests thattoday’s hyperthermophiles are the closest living links to Earth’searliest cells?What is the photoaxis of zooplankton at bottom conditions low light 1?In keeping with the style of Table 17-1, what would youcall organisms that are MM N OO; MM NN OO; MMMNN PP?
- What’s this about bioluminescence in dinoflagellates having evolved, possibly, as an “intrusion alarm”?What is the geoaxis of zooplankton at surface conditions of high light 1?Molecular fossils further indicate the presence of ciliates and dinoflagellates in the emerging eukaryotic world and show that algae were expanding to become major photosynthesizers in the oceans. How can we explain this diversification?
- Why might chemosynthetic communities exist only in places like the deep-ocean floor rather than across a wide range of land and sea habitats, the way photosynthesis-based communities are?Chemolithrophs near hydrothermal vents support a variety of other life forms there. Explain now their role is analogous to that of photosynthetic organisms in the terrestrial environment.What are relictual (plesiomorphic) features? Derived (apomorphic) features? Which organisms seem to have a larger percentage of relictual features—prokaryotes or eukaryotes? Algae or flowering plants? Amoebas or humans?
- Besides adaptation to low light intensities, are there any other adaptations in the photosynthetic pigments found in bacteria that live in the vicinity of deep-ocean thermal vents?______________ require ______________ and ______________, to perform ______________. Question 1 options: Photoautotrophs, water (H2O), carbon dioxide (CO2), photosynthesis Cordatatrophs, potassium superoxide (KO2), water (H2O), chemosynthesis Hemitrophs, iron oxide (Fe2O3), water (H2O), chemosynthesis None of the other answers are correct. Herterotrophs, carbon dioxide (CO2), water (H2O), photosynthesis Simiautotrophs, nitrous oxide (N2O), hydrogen peroxide (H2O2), nucleosynthesisAlthough chemoautotrophs serve as the primary producers near hydrothermal vents, animals there still ultimately depend on the photosynthetic activities of plants and cyanobacteria. Why?
