Answer:
The correct answer is option A) "cause iron in ocean water and terrestrial rocks to rust (oxidize)".
Explanation:
During ancient times, the reproduction success of plants and cyanobacterias led to the accumulation of oxygen gas in the atmosphere. One early consequence of this accumulation was the oxidation of the iron in ocean water and terrestrial rocks. This phenomenon is the cause of banded iron formations, which formed in seawater and sank to the ocean bed.
Cavalier-Smith's model no longer separates prokaryotes and eukaryotes is the statement which differs from kingdom classification.
Explanation:
Cavalier-Smith in 1998 had reduced the kingdom numbers. The were brought down from 8 to 6. These are:
Animalia
Protozoa
fungi
plantae
chromista
bacteria
He divided eukaryotes into 6 kingdoms. The kingdoms are refined for better classification.
While Carolus Linnaeus divided the organisms into two kingdoms
Animalia and plantae.
The five kingdom classification:
Monera (prpkaryotes)
Protista ( unicellular eukaryotes)
fungi (multicellular decomposers)
plantae (multicellular producers)
Animalia (multicellular consumers)
It has drawbacks like in kingdom monera both autotrophs and heterotrophs are included. Phylogeny is not explained in lower organisms of monera and protista. Virus is also in classification. Cavalier-Smith introduced a new kingdom called chromista which are single- celled or multicellular eukaryotic organisms as diatoms, algae, oomycetes and protozoans which perform photosynthesis.
