Why would archaea that grow in extreme environments be more intensively studied than those that do not?
What types of environments are inhabited by archaea? Why are methanogens important?
Which of these is an example of inductive reasoning?
A) Hundreds of individuals of a species have been observed and all are photosynthetic; therefore, the species is photosynthetic.
B) These organisms live in sunny regions. Therefore, they are using photosynthesis.
C) If protists are all single-celled, then they are incapable of aggregating.
D) If two species are members of the same genus, they are more alike than each of them could be to a different genus.
