Question

what phase of mitosis do the chromosomes line up in the middle of the cell?
anaphase
cytokinesis
synthesis
metaphase
interphase

when a cancer has \metastasized\ it means what?
the cancer is benign
the cancer is removable
the cancer is in a cluster
the cancer has spread

what occurs during interphase?
the cell is split into 2
the chromatids separate
the nuclear envelop (membrane) disappears

Explanation:

• For the first question: In mitosis, during metaphase, chromosomes align at the cell's equatorial plane (middle of the cell). Anaphase is when sister chromatids separate. Cytokinesis is the division of the cytoplasm. Synthesis is part of interphase (not a mitosis phase). Interphase is the cell - growth and DNA - replication phase (not a mitosis phase).
• For the second question: Metastasis means cancer cells have spread from the original (primary) tumor to other parts of the body. A benign cancer is non - spreading. Just because a cancer is removable does not mean it has metastasized. A cancer in a cluster does not imply metastasis.
• For the third question: During interphase, the cell grows, replicates its DNA, and prepares for mitosis. The cell splitting into 2 occurs during cytokinesis (part of M - phase). Chromatids separate during anaphase (M - phase). The nuclear envelope disappears during prophase (M - phase).

Answer:

• First question: D. metaphase
• Second question: D. the cancer has spread
• Third question: (None of the provided options are correct. During interphase, the cell grows, replicates DNA, and synthesizes proteins. If we assume there was a typo and the intended correct process related to interphase (e.g., if there was an option like "cell growth and DNA replication"), but based on the given options, there is an error in the question's options)
