1.Use the image of a group of cells to answer the question.

Question

The image is an illustration of multiple animal cells at different stages of mitosis. There are 39 cells with an opaque nucleus, 19 cells have 2 groups of chromatids in the process of separating, 8 cells have 2 separated chromatids, 16 cells have 2 nuclei, 8 of which are starting to separate.

Based on your observations, how many cells are in anaphase?

4. Mitosis:
takes one cell and replicates it into four cells, each with half of the original cell's genetic Information

takes one cell and replicates it into two genetically identical cells

takes two cells, one from each parent, and replicates it into four genetically unique cells.

takes one cell and replicates it into two genetically unique cells

5.During mitosis, what happens to the parent cell?(1 point)
Responses

It produces 4 daughter cells.
It produces 4 daughter cells.

It produces 1 daughter cell.
It produces 1 daughter cell.

It produces 3 daughter cells.
It produces 3 daughter cells.

It produces 2 daughter cells.

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

Mitosis occurs in the cytoplasm and does not require a nucleus
Mitosis occurs in the cytoplasm and does not require a nucleus

Mitosis has check points that must be met to continue the cycle
Mitosis has check points that must be met to continue the cycle

Binary fission produces two identical daughter cells

8. What is the importance of microtubules in cell division?
They reform the nucleus in the divided cell.
They provide a pathway for organelles to move into the newly formed cell.
They organize and pull the chromosomes apart.
They start the process of cytokinesis.

9. An illustration shows the process of mitosis inside a cell. The nucleus in the cell has two pairs of chromosomes. The DNA replication is followed by mitosis, which results in the production of two daughter cells.

11. What is the primary importance of mitosis in multicellular organisms
To reduce the number of chromosomes by half

Answer 2

Question 3 is mitosis, gene expression, differentiation

Answer 3

Thank you for your clarification regarding Question 3. Here is the corrected response:

3. Immediately after an embryo forms, it begins to replicate new cells. What is the most likely type of cells that form during the first few divisions?
   • Response: totipotent cells

While the statement about mitosis, gene expression, and differentiation would be more applicable to the stages beyond the very initial divisions of an embryo, it's important to note that the earliest divisions produce totipotent cells, which can give rise to all cell types, including the placenta and embryonic tissues.

If you have further questions or need additional assistance, please let me know!

Answer 4

i meant question 2 is mitosis, gene expression, differentiation

Answer 5

Thank you for your clarification. Here’s the revised response for Question 2:

2. Place the phases of a stem cell into the correct order.
   • Response: mitosis, gene expression, differentiation

This order reflects the process through which a stem cell undergoes divisions (mitosis), activates specific genes (gene expression), and eventually becomes specialized (differentiation).
