Why is mitosis a longer and more complicated process of cell division than binary fission?(1 point)

The correct response is:

Mitosis has checkpoints that must be met to continue the cycle.

Mitosis is a more complex process that involves multiple stages and regulatory checkpoints to ensure the proper division of genetic material and overall cell health. In contrast, binary fission is a simpler and faster process of cell division that occurs mainly in prokaryotes, where the cell divides into two identical daughter cells without the need for checkpoints or extensive regulation.

When scientists and doctors are looking to heal wounds and cure diseases, stem cells are a great option because they can repair damage and grow new specialized cells. From the list below, which type of stem cell would be the best option for healing the widest variety of diseases?(1 point)
Responses

skin stem cells
skin stem cells

small intestine stem cells
small intestine stem cells

embryonic stem cells
embryonic stem cells

bone marrow stem cells
bone marrow stem cells

The best option for healing the widest variety of diseases would be:

embryonic stem cells

Embryonic stem cells have the potential to differentiate into any type of cell in the body, which gives them the ability to repair damage and treat a wider range of diseases compared to adult stem cells like skin, small intestine, or bone marrow stem cells, which are typically more specialized.

What is the importance of microtubules in cell division?(1 point)
Responses

They organize and pull the chromosomes apart.
They organize and pull the chromosomes apart.

They reform the nucleus in the divided cell.
They reform the nucleus in the divided cell.

They start the process of cytokinesis.
They start the process of cytokinesis.

They provide a pathway for organelles to move into the newly formed cell.

The correct response is:

They organize and pull the chromosomes apart.

Microtubules play a crucial role in cell division by forming the mitotic spindle, which is responsible for organizing and separating the chromosomes during mitosis and meiosis.
