1. Describe the actions of the cell's chromosomes during metaphase, a stage of mitosis.
a. They condense to become chromatin.
b. They move toward the poles of the cell.
c. They duplicate.
d. They line up in the middle of the cell.

The correct answer is Option d. They line up in the middle of the cell.

Explanation:

Metaphase is a stage of mitosis in which condensation of DNA molecule into chromosomes occurs. During metaphase, nucleus is disappeared and chromosome becomes visible in the cytoplasm of the cell. There, the chromosomes line up in the middle of the cell.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
