Answer:
20%
Explanation:
cytosine = guanine = 30%
cytosine + guanine = 60 %
adenine + thymine =100% - 60% = 40 %
thymine = 20%
Answer:
d) genetic characteristics such as ribosomal RNA sequences
Explanation:
Carl Woese and his collaborators identified two major branches of prokaryotic evolution which are bacteria and archaea. They used 16S rRNA sequencing to study the similarities and differences between archaea and bacteria.
After sequencing the complete genome structure of Methanococcus jannaschii in 1966 which is an archaea they concluded that bacteria are more closely related than humans than bacteria.
After many years Carl Woese gave the three-domain system which divides prokaryotes into archaea and bacteria according to differences in their rRNA sequencing. Eukarya was the third domain. So the correct answer is d.

Answer:
The hippocampus is important in helping the brain to STORE NEW MEMORIES.
Explanation:
People with damage to their hippocampus have virtually no capability of storing verbal or declarative types of memory in long -term memories, that is, they are unable store types of information that are the basis of intelligence. This is often called ANTEROGRADE AMNESIA.
Hippocampi are important in the output pathway from the reward and punishment areas of the limbic system among other structures.
Sensory stimuli or thoughts that cause pain excite the limbic punishment centers while stimuli that cause pleasure, happiness excite to reward centers. Hippocampi especially have a part to play in the response of the brain in making decisions about which of the thoughts are important on the basis of reward or punishment to be good for storing as memories. So any lesion or damage to this area causes loss of memory of the recent happenings both in long and intermediate term.
