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?

Answer 1

In the description provided, you mention that 19 cells have 2 groups of chromatids in the process of separating. This indicates that these cells are in anaphase, as anaphase is characterized by the separation of sister chromatids to opposite poles of the cell.

Therefore, the number of cells that are in anaphase is 19.

Answer 3

The correct order of the phases of a stem cell is:

mitosis, gene expression, differentiation.

This sequence represents the process in which stem cells first undergo division (mitosis), then activate specific genes that will lead to their specialization, and finally, they differentiate into specific cell types.

Answer 4

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? (1 point)
multipotent cells
oligopotent cells
pluripotent cells
totipotent cells

Answer 5

Immediately after an embryo forms, the most likely type of cells that form during the first few divisions are totipotent cells.

Totipotent cells are the most versatile type of stem cells, capable of developing into any cell type in the body, including the extraembryonic tissues (like the placenta). This ability is present in the early stages of an embryo, right after fertilization.

Answer 6

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

Answer 7

The correct description of mitosis is:

takes one cell and replicates it into two genetically identical cells.

Mitosis is the process of cell division that results in two daughter cells, each having the same number of chromosomes and genetic material as the original cell.

Answer 8

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.

Answer 9

During mitosis, the parent cell:

It produces 2 daughter cells.

Mitosis results in the division of one parent cell into two genetically identical daughter cells.

Answer 10

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
Binary fission produces two identical daughter cells

Binary fission does not replicate DNA

Answer 11

The correct response is:

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

Mitosis is a more complex process than binary fission because it involves multiple stages (prophase, metaphase, anaphase, and telophase) and regulatory checkpoints to ensure that the cell is ready to divide and that the genetic material is accurately replicated and distributed. Binary fission, on the other hand, is a simpler process typically seen in prokaryotes, where the cell divides directly into two identical daughter cells without such regulatory mechanisms.
