The correct response is have limitations.

Scientific models are simplifications of reality and are used to explain, predict, and understand complex systems or phenomena. However, they always have limitations, as no model can capture every detail of the real world.

The following diagram shows the mitotic process.

A parent cell is shown on the left. The nucleus and chromosomes are labeled. An arrow points to two daughter cells on the right. The arrow is labeled DNA replication, then mitosis.

What is a limitation of this diagram?

Responses

It does not show that mitosis creates more than two daughter cells. It only shows a polyploidy cell in mitosis.
It does not show that mitosis creates more than two daughter cells. It only shows a polyploidy cell in mitosis.

It does not show all phases of mitosis.
It does not show all phases of mitosis.

It does not show senescence. It only shows the interphase portion of mitosis.
It does not show senescence. It only shows the interphase portion of mitosis.

It does not show the final result of mitosis.

The correct response is It does not show all phases of mitosis.

This limitation highlights that while the diagram may illustrate the overall process of mitosis, it does not provide detailed information about the individual phases (prophase, metaphase, anaphase, and telophase) that occur during mitosis.

What is a limitation of a pictorial-only model of mitosis that shows detailed images of the different phases of the process?(1 point)
Responses

The division of cells are not shown in models of mitosis.
The division of cells are not shown in models of mitosis.

It does not name the different phases of mitosis.
It does not name the different phases of mitosis.

It does not provide any information about what happens during mitosis.
It does not provide any information about what happens during mitosis.

Chromosomes are not shown in models of mitosis.

The correct response is It does not provide any information about what happens during mitosis.

A pictorial-only model may visually represent the phases of mitosis but might lack explanatory text or context that describes the processes and events occurring during each phase.

Use the image to answer the question.

The cell cycle begins with interphase, where the cell takes approximately 10 hours to grow. If it passes the G1 checkpoint, the DNA duplication starts and goes on for approximately eight hours. The cell further grows for approximately four hours. After passing the G2 checkpoint, the process of mitosis takes place, which takes approximately one to two hours. The phases during mitosis are prophase, metaphase, anaphase, telophase, and cytokinesis. After cytokinesis, the daughter cells enter interphase, and the cycle gets repeated.

According to the figure, mitosis occurs after which stage in the cell cycle?

The correct response is G2.

Mitosis occurs after the G2 stage in the cell cycle, following the G2 checkpoint.

A model illustrating the splitting of the cell in cytokinesis.
A model illustrating the splitting of the cell in cytokinesis.

A model with all four phases of mitosis in order, showing the chromosomes inside.
A model with all four phases of mitosis in order, showing the chromosomes inside.

A model listing the four phases of mitosis without showing what happens inside the cells.

The correct response is A model with all four phases of mitosis in order, showing the chromosomes inside.

This model would provide the most accurate representation of the mitotic process by illustrating the stages in order and depicting the behavior of chromosomes during each phase of mitosis.
