Answer: Achaea.
Archaea are prokaryotic cells found in extreme, harsh environment.
Explanation:
Archaea are single celled prokaryotic microorganisms that lack cell nuclei.Archaea are extremophiles that live in extreme high and harsh environments like hot springs and salt lakes.They reproduce asexually by binary fission, fragmentation and budding. They are salt tolerant that use sunlight as energy.
The new species come from old ancestors of the animals that were there, over time they slowly evolved, and they adapted to that new environment.
Answer:
The correct answer is statement d.
Explanation:
In oxidative phosphorylation that takes place in mitochondria, the uncouplers prevent the coupling in between the phosphorylation reactions and electron transport, and therefore, prevent the synthesis of ATP without influencing the ATP synthase and respiratory chain.
The uncoupler always exhibits its influence on the synthesis of ATP. The 2,4-dinitrophenol functions as an uncoupler at the time of oxidative phosphorylation. The NADPH and FAD functions as an electron carrier.
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.
