Which of the following observations about flagella is accurate and is consistent with the scientific conclusion that the flagella from archaea and bacteria evolved independently? a) the flagella of the two groups differ in size. b) the protein structures in the flagella are different c) the mechanisms of rotation are similar both groups have flagella like those found in eukaryotes

The correct answer is option B) "The protein structures in the flagella are different".

Explanation:

Although both archaea and bacteria have flagella, the composition and likely the assembly of the flagella is very different from the two clades. In this sense, one observation that is accurate with the scientific conclusion that the flagella from archaea and bacteria evolved independently is that the protein structures in the flagella are different between them. Furthermore, no homologous of bacterial genes responsible for flagella synthesis had been found in archaea.

the correct answer is option d.

an appositive is a noun, noun phrase or noun clause which follows another noun or noun phrase in order to describe it or name it another way. they are usually used between commas, brackets or dashes.

the example sentence with the correct use of commas is the following:
