Answer:
<u>C. The coastlines of South America and Africa were similar in shape, suggesting that they shared a common tectonic plate.</u>
Explanation:
- As suggested by the Alfred Wegener, the plates of the South America and the African plants had a similar geologic history and thus shared a common tectonic boundary and hence validate the proof of the superclass and the drifting of the plates at various time zones.
- Thus after the 1960s the plate tectonic theory came into the limelight and was heavily recognized to be fit the works of the drifting of the continental landmasses.
Answer:
The correct answer is A) Have diverse cell wall compositions
Explanation:
Both bacteria and archaea comes under prokaryotes because they both lack a membrane-bound nucleus. The difference between archaea and bacteria is in their cell wall composition.
The bacterial cell wall is made up of peptidoglycan and the archeal cell wall is made up of pseudo-peptidoglycan. In bacteria, peptidoglycan contains N acetyl muramic acid and N acetyl glucosamine unit but in archaea, the N acetyl muramic unit is replaced by some other unit and the linkage of two units is also different in archaea. So the right answer is A.
Answer:
Ependymal cell present in the central nervous system has an important role in production and control of cerebrospinal fluid (CSF). This ciliated cell acts as sensory for coordination to cellular signaling in the production and control of CSF.
