Answer:
B. Sympatric speciation, habitat differentiation.
Explanation:
The right answer to our question is B, Sympatric speciation, habitat differentiation.
Edward Bagnall Poulton derived the term sympatric speciation in 1904. It is a mode of speciation, which entails new species emerging from an ancestral species that is still alive and extant. Both the emerging and ancestral species will exist in the same zone.
This speciation is found more in plants. There are different types of these speciations. Habitat differentiation is seen within sympatric speciation. It is found when mutations that exist in the same zone can make use of varying conditions. Allopatric speciation and parapatric speciation are the other types of speciation.
Chemical weathering by carbonation
Explanation:
Chemical weathering by the process of carbonation will cause the inscription on a marble gravestone to become more difficult to read with time.
Chemical weathering is the decomposition and decay of rocks to form sediments and soil.
- Marble is metamorphic carbonate rock.
- It is derived from the metamorphism of limestone and dolomitic rocks.
- In the presence of weak carbonic acid, it becomes soluble
- Carbonic acid is formed when atmospheric carbon dioxide combines with rain water.
- The carbonic acid dissolves the marble and washes it away in solution.

The first step in the titration process is; A measured volume of an acid or base of (un)known concentration is added to a flask. The second step is several drops of indicator are added to the solution, and the third step is ; the measured volumes of a base or acid of known concentration are added, using a burette, until the indicator just barely changes color (end point or the equivalence point).
Answer: the body plans of complex animals are very similar to one another
