become quiescent quickly.

GPT-4o mini · Answer

Skin cells can be described by the following statement:

have terminally differentiated.

Skin cells, specifically keratinocytes, are differentiated cells that make up the outer layer of the skin. Once they differentiate, they have a specific function and do not typically divide further, which is why they are considered terminally differentiated. While skin cells can also become senescent or quiescent under certain conditions, the primary and most accurate statement here is that they have terminally differentiated.

e · Answer

Which cell type undergoes terminal differentiation?(1 point) Responses epithelial cells epithelial cells heart cells heart cells stem cells stem cells hair cells

GPT-4o mini · Answer

The correct response is: **stem cells.** Stem cells have the potential to undergo terminal differentiation into various specialized cell types, including epithelial cells, heart cells, and hair cells. Terminal differentiation means that the cell has reached a stage where it has specialized in function and typically will not divide further. While epithelial cells, heart cells, and hair cells themselves are terminally differentiated, the question asks which type undergoes terminal differentiation, which refers to stem cells as they can differentiate into multiple cell types.

In eukaryotic cells, DNA replicates in the(1 point) Responses endoplasmic reticulum. endoplasmic reticulum. cell membrane. cell membrane. cytoplasm. cytoplasm. nucleus. nucleus.

GPT-4o mini · Answer

The correct response is: **nucleus.** In eukaryotic cells, DNA replication occurs in the nucleus, where the cell's genetic material is housed.

e · Answer

Which of the following is a function of mitosis? (1 point)
Responses

to make a cell exit the cell cycle
to make a cell exit the cell cycle

to send chemicals signals throughout the body
to send chemicals signals throughout the body

to cause a cell to grow
to cause a cell to grow

to repair damaged tissue

GPT-4o mini · Answer

The correct response is: **to repair damaged tissue.** Mitosis is a process of cell division that results in two genetically identical daughter cells and plays a key role in growth, development, and tissue repair. While it does contribute to cell growth, its specific function in the context of this question is more aligned with repairing damaged tissue.

e · Answer

What replicates during mitosis?(1 point) Responses cells cells cytoplasm cytoplasm organelles organelles proteins

GPT-4o mini · Answer

The correct response is: **cells.** During mitosis, a parent cell divides to produce two genetically identical daughter cells. While other components, such as organelles and cytoplasm, may be distributed between the daughter cells, the primary process of mitosis specifically refers to the replication and division of the entire cell, including its nucleus.
