“C” is the correct answer
Answer:
Here, should be the options to complete the question
1) Cells divide by constriction of a
ring of protein
2 The presence of a cell wall
prevents the cell from dividing by
constriction
3) Tubulin or tublin-like molecules
function in binary fission (in
bacteria) or cytokinesis (in animals
and plants)

Answer:
A. The I bands and H bands get smaller and the A bands remain the same size.
Explanation:
The dark-colored central region of the sarcomere that extends the entire length of the thick filaments makes the A band. It also includes the part of the thin filaments that overlap the thick filaments. The lighter region of the sarcomere consisting of the rest of the thin filament but no thick filament makes the I band. The H zone is the narrow region present in the center of each A band and consists only of thick filaments.
During muscle contraction, myosin heads pull the thin filaments towards the M line. This makes the thin filaments to slide inward to allow their ends to overlap and meet at the center of the sarcomere. This makes the I band and H zone narrower. The I band and H zone are disappeared during maximum muscle contraction. Sliding of thin filaments does not change the width of A band which remains unchanged.
It uses two-word system based on descriptions of the animal
