These structures are composed of the 9+2 arrangement of tubulin polymers.

Cilia and flagella.

Explanation:

Tubulin is the protein that acts the monomer of microtubules. Microtubules helps in the cellular motility, maintains the cell shape and helps in the movement of organelles.

Microtubules arrangement are different in different cell types. The 9+ 2 cell arrangement of the cell occurs in cilia and flagella. Dynein attaches the arms of the microtubules in the 9+2 arrangement of the cilia and flagella. Cilia and flagella are involved in motility process.

Thus, the answer is cilia and flagella.

answer: oceans, duh

correct answer: biotic and abiotic limitations
