They are eukaryotes They are a clade They are polyphyletic They are extremely diverse What do the permafrost and peat bogs have in common? These are both ecosystems that are dominated by extremophile Achaeans They provide examples of what happens when microbial saprobes are inhibited These are two of the ecosystems with the highest microbial diversity in the world Below is a phylogenetic tree for Poison Dart Frogs. What would we call a taxonomic category that included just the Epipedobates and the Phyllobates?

Answer 1

Answer= the following are not true about protists as a taxonomic group

1]They are a clade =A clade is a group of organisms that we believed evolved from a common ancestor

protists are diverse & do not have one exclusive common ancestor .

protists are not a clade

this is not true

2] They are polyphyletic = polyphyletic means it is a taxon that does not contains most recent common ancestors of its members .

protists are paraphyletic as the representative taxa do not contains all descendants of their stem species .

the incorrect options are

1] they are eukaryotes = the kingdom protists are unicellular eukaryotes .

some protists like seaweed

2] They are extremely diverse = protists are a diverse group of organisms that are either unicellular or multicellular .

without highly specialized tissues .

they include one cell animal like -protozoa ,one cell -algae ,slime molds & water molds
