flagella - ANSWER ✔✔Rhodobacter spheroides has the ability to
swim quickly through water toward light, which is necessary for
photosynthesis. This type of directional movement is characteristic of:
Eukarya and Archaea diverged from a common ancestor more recently
than they diverged from their common ancestor with Bacteria. -
ANSWER ✔✔Which statement most accurately describes the
evolutionary relationships among the three domains?
- ANSWER ✔✔Archaea have very diverse environmental
requirements and tolerances. From what you have learned about them,
,which among the following conditions or substances do ALL archaeans
require for survival and reproduction?
thylakoids - ANSWER ✔✔The photosynthetic activity of
cyanobacteria takes place in their:
mutualist - ANSWER ✔✔The proteobacterium Rhizobium lives in a

organism that:
cyanobacteria - ANSWER ✔✔The evolution of organisms that use
oxygen in their respiration was possible only because of the action of a
group of bacteria that produced oxygen and changed the Earth's
atmosphere from an anoxic one to one rich in oxygen. That group of
bacteria was:
, True - ANSWER ✔✔True or False
Most extremophiles are archaea.
horizontal gene transfer - ANSWER ✔✔The process by which genetic
material is exchanged between different species, such as an
endosymbiont and its host, is:
malaria - ANSWER ✔✔Plasmodium falciparum is a protistan
parasite, borne by mosquitoes, that constitutes a serious health problem
for humans. The disease it causes is:
Euglena (a unicellular alga) - ANSWER ✔✔Which protist would most
likely be phytoplankton?
-Kelp (a brown seaweed)
-Plasmodium falciparum (the
pathogen that causes malaria)
-Polysiphonia (a red seaweed)
-Euglena (a unicellular alga)
