identify the choice that best completes the statement or answers the question. what is the structure labeled x in the figure above?
a. spindle fiber
b. centriole
c. chromosome
d. nucleus
question 1.
question 2.
after the pictures shown in the figure above have been arranged in the correct order, what would a diagram of the final step show?

Explanation:

Step1: Analyze the structure labeled X

In the mitosis diagram, the structure labeled X (looking at the typical mitosis figures) - spindle fibers are the structures that attach to chromosomes and help in their movement. Centrioles are part of the centrosome, chromosomes are the condensed DNA structures, and nucleus is the organelle. The structure X in the mitotic figure (probably metaphase or anaphase related) is a spindle fiber. So option A is correct.

Step2: Confirm the identification

By recalling the components of mitotic apparatus: spindle fibers are the thread - like structures that form the mitotic spindle. Centrioles are the small organelles near the spindle, chromosomes are the condensed DNA, and nucleus is the membrane - bound organelle. So the structure labeled X is a spindle fiber.

Answer:

A. Spindle fiber
