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.
The parasympathetic nervous system <span>conserves energy as it slows down heart rate, increases intestinal and glandular activity, and relaxes the sphincter muscles of the gastrointestinal tract. It gets the nickname "rest and digest" for doing exactly so.

Mitochondria. The “powerhouses” of the cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate).
In one class of response, B cells secrete antibodies that neutralize the virus.
Answer:
Increased by two to ten percent.
Explanation:
The exercise improves the flexibility and strength of the individual. Exercise involves the different postures and activities depending on the type of exercise and need of individual.
The difficulty level of the exercise starts from simple and then move to the moderate and hard level. The different amount of the loads are given to the individual during the exercise. If an individual can easily handle the load, this load can be gradually increased from 2 % to the 10% depending on the individual's ability.
Thus, the correct answer is option (2).
