Answer:

Answer is Yes for eukaryotic flagella and , no for bacterial flagella.

Explanation:

Note that, a flagellum is a slender appendage structure  just like a thread, enabling some protozoa, spermatozoa among others to move or swim from a point to another.

The bacterial flagella is simple and small, and made up of protein, while the eukaryotic flagella are large and somewhat complex, and composed of tublin.

In this case, the eukaryotic flagella will be seen simply because they are larger, and extended out from the surface of the cell.

Answer:

The correct answer will be option D (they are complementary).

Explanation:

Complementary DNA or cDNA is an edited DNA molecule synthesized from a single-stranded RNA called mRNA. The reaction of cDNA formation from mRNA is catalyzed by an enzyme called "reverse transcriptase".

The cDNA strands formed is also known as a complementary copy of mRNA as it contains no introns or non-coding sequence in its sequence similar to mRNA. cDNA is used in recombinant DNA technology to clone eukaryotic genes in prokaryotes.

Thus, option D (they are complementary) is the correct answer.

Which chain of volcanic islands is not part of a convergent/subduction plate boundary?
frutty [35]

Hawai'an volcanic islands

Hawai'an volcanic islands is not part of a convergent/subduction plate boundary.

<h3>What kind of plate boundary produces a sequence of volcanic islands?</h3>
  • convergent boundary
  • Along the convergent boundary, the new magma (molten rock) rises and may erupt violently to form volcanoes, frequently creating arcs of islands.
  • Divergent plate boundaries are created when two plates are moving apart.

<h3>Why do volcanic chains and convergent borders coexist?</h3>
  • Subduction causes melting that is partially molten.
  • Water loss in the plate causes partial melting.
  • Mantle material melts as a result and rises to the surface.

<h3>Which are the 4 types of convergent boundries?</h3>
  • Divergent Plate Boundary.
  • Convergent Plate Boundary.
  • Transform Plate Boundary.
  • Hotspot.
