Answer:
c. to account for two major and distinct prokaryotic groups in addition to eukaryotes.
Explanation:
Microbiologist Carl Woese compared the ribosomal RNA sequence of the small subunit of RNA. Various organisms have structurally different small subunit of the ribosomes. According to Woese the molecular composition of rRNA in closely related organisms should be more similar than in distantly related organisms. He analyzed the 16S rRNA of various organisms and observed that there are two distinct groups of prokaryotes. He divided the prokaryotes among two domains: Bacteria and Archaea. He placed all the eukaryotes in the domain Eukarya.
Answer:
Each year, earthworms move deep into soil during fall and winter and return toward spring and summer. The likely stimulis for this behavioral response are relative humidity & temperature. Since the nematode breathes via the skin, the mucus coating may become dry & the organism would die if exposed to extreme cold & dryness.
