The answer is b) cleavage furrow.

Explanation for each option:

a) Anaphase plate: This term is not typically used in the context of cytokinesis. It refers to the stage during mitosis when chromosomes are aligned at the metaphase plate, not involved in the physical division of the cell.

b) Cleavage furrow: This is the correct answer. In animal cells, cytokinesis involves the formation of a cleavage furrow, which is a contractile ring that pinches the cell membrane to divide the cell into two daughter cells.

c) Cell plate: This is incorrect for animal cells. The cell plate is involved in cytokinesis in plant cells, where it forms to separate the two daughter cells.

d) Beads-on-a-string DNA: This term refers to the structure of chromatin, where DNA is wrapped around histone proteins, resembling beads on a string. It is not related to cytokinesis.

In summary, cytokinesis in animal cells involves the formation of the cleavage furrow.

Consider the following intermediate tableau (not the Initial Simplex tableau): [ P x1 x2 x3 s1 s2 RHS 0 0 2 -1 1 -1 4 0 1 0 1 0 1 8 1 0 -3 -2 0 2 16 ] a) Determine the pivot column and the pivot element, and perform the necessary row operations to convert the pivot element into 1 and the other numbers in the pivot column to 0. Once you obtain the new tableau this way, look at the numbers you have in the objective row (the bottom row) and enter each one as requested in each box below. Note: Where applicable, fractions must be entered as 2 / 5, -1 / 3, and so on. Under column x1 in the objective row, you have: Under column x2 in the objective row, you have: Under column x3 in the objective row, you have: Under column s1 in the objective row, you have: Under column s2 in the objective row, you have: Under column RHS in the objective row, you have:
