Answer 1

Skin cells can be described in different ways depending on the specific type of skin cell.

1. Become senescent quickly: Skin fibroblasts, for example, can undergo senescence due to environmental stressors or replicative exhaustion, but not all skin cells do this quickly.

2. Have terminally differentiated: Some skin cells, like keratinocytes, are considered terminally differentiated because they have completed their development and no longer divide.

3. Become quiescent quickly: Certain skin cells, such as stem cells in the hair follicle, can enter a quiescent state but are not typically characterized as becoming quiescent quickly.

4. Are stem cells: There are specific stem cells present in the skin, like epidermal stem cells in the basal layer, which can give rise to different skin cell types.

Depending on context, you can select the statement that fits best for the type of skin cell in question.

Answer 3

The best single answer for skin cells is:

have terminally differentiated.

This statement applies well to keratinocytes, the most abundant type of skin cell, which are considered terminally differentiated as they mature and eventually die off.

Answer 5

The best answer for which cell type undergoes terminal differentiation is:

epithelial cells.

Epithelial cells, such as keratinocytes in the skin, undergo terminal differentiation as they progress through their life cycle, ultimately becoming specialized and non-dividing cells.

Answer 7

In eukaryotic cells, DNA replicates in the:

nucleus.

This is where the cell's genetic material is housed and where replication occurs before cell division.

Answer 9

The correct answer is:

to repair damaged tissue.

Mitosis is the process of cell division that results in two daughter cells and is primarily responsible for growth, development, and repair of tissues.

Answer 11

The correct answer is:

cells.

During mitosis, a single cell divides to produce two identical daughter cells, each with the same genetic material as the original cell. While organelles and cytoplasm are distributed between the daughter cells, it is the cells themselves that are replicated through the process of mitosis.

Answer 12

Which answer choice correctly lists the steps of mitosis in order? (1 point)
Responses

Telophase, anaphase, metaphase, prophase
Telophase, anaphase, metaphase, prophase

Prophase, metaphase, anaphase, telophase
Prophase, metaphase, anaphase, telophase

Metaphase, anaphase, telophase, prophase
Metaphase, anaphase, telophase, prophase

Prophase, anaphase, metaphase, telophase

Answer 13

The correct answer choice that correctly lists the steps of mitosis in order is:

Prophase, metaphase, anaphase, telophase.

These are the standard phases of mitosis that occur sequentially during cell division.
