B. Sympatric speciation, habitat differentiation.
C. Allopatric speciation, behavioral isolation.
D. Sympatric speciation, sexual selection.
E. Sympatric speciation, allopolyploidy.
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.
In the given scenario, Sympatric speciation driven by habitat differentiation has occurred. The different 'habitats' are represented by the flower color preferences of the beetle variants, leading them to diverge to the point of becoming distinct species.
The type of speciation that has occurred in the provided scenario is Sympatric speciation, driven by habitat differentiation. In this context, sympatric speciation refers to the process where new species evolve from a single ancestral species while inhabiting the same geographic region. In this case, the 'geographic region' is the color of the flowers. The red and orange flowers represent different 'habitats' for the beetles.
In terms of what has driven this speciation, it is habitat differentiation. This is because even though the beetles are occupying the same general physical area, their 'habitat' in terms of the color of the flowers they prefer has caused a divergence in their mating and, hence, their gene pools. Over time, this leads to the two beetle variants becoming so different that interbreeding is no longer possible, effectively rendering them distinct species.

None of the above
B. spirilli
C. bacilli
D. filamentous
The term for rod-shaped bacteria is 'bacilli'. This category is a part of the larger classification in microbiology based on bacterial shape, which also includes cocci for spherical bacteria and spirilli for spiral-shaped bacteria.
In the field of Biology, particularly microbiology, bacteria are often categorized based on their shape. For bacteria that are shaped like rods, the term used is bacilli. This contrasts with other shapes, such as cocci (spherical) and spirilli (spiral-shaped). For instance, Bacillus subtilis is a type of rod-shaped bacteria, which demonstrates the morphological type bacilli.
The correct answer is C. bacilli. Bacteria that are shaped like rods are called bacilli. These bacteria have a cylindrical shape and can be found in various environments, such as soil, water, and the human body. Some examples of bacilli include E. coli and Salmonella.
