dividing animal cells are pinched in two by:
the cell plate
centromeres
the mitotic spindle
contraction of actin filaments
kinetochores

Explanation:

• The cell plate is involved in plant cell division, not animal cell division.
• Centromeres are regions on chromosomes.
• The mitotic spindle helps in chromosome separation.
• Kinetochores are protein structures on chromosomes.
• In animal cell division, the cleavage furrow is formed by the contraction of actin filaments (along with myosin), which pinches the cell in two.

Answer:

contraction of actin filaments
