Totipotent cells have the potential to develop into any cell type in the body, including the cells needed to form the placenta and other extraembryonic tissues.
Why is mitosis a longer and more complicated process of cell division than binary fission?(1 point)
Responses
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
Binary fission does not replicate DNA
Mitosis occurs in the cytoplasm and does not require a nucleus
The correct response is:
Mitosis has checkpoints that must be met to continue the cycle.
Mitosis is a more complex process than binary fission because it involves multiple stages, regulatory checkpoints, and the separation of duplicated chromosomes, ensuring that the daughter cells receive the appropriate complement of genetic material. Binary fission, on the other hand, is a simpler process used by prokaryotic cells that typically involves direct replication and division without such checkpoints.
Some differentiated cells become senescent almost immediately, leaving the cell cycle and undergoing terminal differentiation. Other cells have a high need to proliferate in order to grow and repair the organ or tissue, so they do not enter senescence for a long period of time. Which cell type would be most likely to put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair?(1 point)

The cell type most likely to put off senescence and terminal differentiation in order to continue replicating for growth and repair is skin cells.
Skin cells are constantly being shed and replaced, and they have a high turnover rate, which allows them to proliferate and repair the tissue effectively. In contrast, heart cells and brain cells generally have much lower rates of regeneration and can enter senescence more readily.

They provide a pathway for organelles to move into the newly formed cell.
They organize and pull the chromosomes apart.
The importance of microtubules in cell division is that they organize and pull the chromosomes apart.
Microtubules form the spindle apparatus, which is essential for the proper separation of chromosomes during mitosis. They attach to the kinetochores of chromosomes and help ensure that each daughter cell receives the correct number of chromosomes.
How is cell differentiation different than mitosis?(1 point)
Responses
Cell differentiation does not cause proliferation.
Cell differentiation does not cause proliferation.
Cell differentiation produces cells with different gene expressions.
Cell differentiation produces cells with different gene expressions.
Cell differentiation produces cells with different DNA.
Cell differentiation produces cells with different DNA.
Cell differentiation only occurs after a wound.
The correct response regarding how cell differentiation is different from mitosis is:
Cell differentiation produces cells with different gene expressions.
Cell differentiation is the process by which a cell changes from one cell type to another, often becoming more specialized, and involves changes in gene expression. In contrast, mitosis is the process of cell division that results in two genetically identical daughter cells and does not inherently involve changes in gene expression.

To accurately determine the type of cell shown in the figure, I would need to see the figure or have a description of it. However, I can provide definitions for each type of cell:
Haploid cell: A cell with one complete set of chromosomes (n); for example, a sperm or egg cell.
Diploid cell: A cell with two complete sets of chromosomes (2n); for example, a somatic (body) cell in humans.
Triploid cell: A cell with three complete sets of chromosomes (3n).
Polyploid cell: A cell with more than two complete sets of chromosomes (e.g., tetraploid with 4n).

Explain what it most likely means for a daughter cell to be identical to its mother cell:(1 point)
Responses
A daughter cell is "identical" to its mother cell if it contains the same composition of organelles
A daughter cell is "identical" to its mother cell if it contains the same composition of organelles
A daughter cell is "identical" to its mother cell if it contains different genetic information
A daughter cell is "identical" to its mother cell if it contains different genetic information
A daughter cell is "identical" to its mother cell if it contains the same genetic information
A daughter cell is "identical" to its mother cell if it contains the same genetic information
A daughter cell is "identical" to its mother cell if it contains a different composition of organelles
The correct response is:
A daughter cell is "identical" to its mother cell if it contains the same genetic information.
In the context of cell division, particularly during mitosis, daughter cells are produced that maintain the same genetic information as the parent (mother) cell. This ensures that the daughter cells are genetically identical to the original mother cell, allowing for proper functioning and continuity of traits.
Predict why daughter cell II will or will not be considered a product of mitosis.(1 point)
Responses
Daughter cell II will be considered a product of mitosis because it has the same amount of DNA as the parent cell.
Daughter cell II will be considered a product of mitosis because it has the same amount of DNA as the parent cell.
Daughter cell II will be considered a product of mitosis because it has half the amount of DNA as the parent cell.
Daughter cell II will be considered a product of mitosis because it has half the amount of DNA as the parent cell.
Daughter cell II will not be considered a product of mitosis because it has half the amount of DNA as the parent cell.
Daughter cell II will not be considered a product of mitosis because it has half the amount of DNA as the parent cell.
Daughter cell II not will be considered a product of mitosis because it has the same the amount of DNA as the parent cell
Daughter cell II not will be considered a product of mitosis because it has…
The correct response is:
Daughter cell II will be considered a product of mitosis because it has the same amount of DNA as the parent cell.
In mitosis, the process involves the division of a parent cell into two daughter cells, each of which contains the same amount of DNA (and therefore the same genetic material) as the parent cell. If Daughter Cell II has the same amount of DNA as the parent cell, it is indeed a product of mitosis.
Describe the relationship between cell III and the mother cell seen above.(1 point)
Responses
Cell III is not identical to the mother cell but is still produced when it undergoes a meiotic division.
Cell III is not identical to the mother cell but is still produced when it undergoes a meiotic division.
Cell III is identical to the mother cell (prior to DNA replication) and is produced when it undergoes a meiotic division.
Cell III is identical to the mother cell (prior to DNA replication) and is produced when it undergoes a meiotic division.
Cell III is identical to the mother cell (prior to DNA replication) and is produced when it undergoes a mitotic division.
Cell III is identical to the mother cell (prior to DNA replication) and is produced when it undergoes a mitotic division.
Cell III is not identical to the mother cell but is still produced when it undergoes a mitotic division.
The most appropriate response is:
Cell III is not identical to the mother cell but is still produced when it undergoes a meiotic division.
In meiosis, cells undergo two rounds of division (meiosis I and meiosis II) which results in daughter cells that have half the number of chromosomes and are genetically different from the original mother cell. Therefore, Cell III, being a product of meiosis, would not be identical to the mother cell.
