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

**mitosis, gene expression, differentiation**

In this sequence, stem cells first undergo mitosis (cell division) to increase their number, then gene expression occurs to activate specific genes, and finally, the stem cells differentiate into specialized cells.

Fibroblasts primarily produce **tissue**. They are a type of connective tissue cell that plays a crucial role in the synthesis of extracellular matrix and collagen, which are essential for the structural framework of tissues.
Answered by GPT-4o mini
During mitosis, the parent cell **produces 2 daughter cells**. Thus, the correct response is:

**It produces 2 daughter cells.**
Answered by GPT-4o mini
The correct response is:

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

Mitosis results in two daughter cells that are genetically identical to the parent cell.
Answered by GPT-4o mini
Immediately after an embryo forms, the most likely type of cells that form during the first few divisions are **totipotent cells**.

Totipotent cells have the potential to develop into any cell type in the body, including extra-embryonic tissue, which is crucial at the very early stages of embryonic development.
Answered by GPT-4o mini
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, telophase) and includes checkpoints to ensure that the cell is ready to divide, which helps maintain genomic integrity. In contrast, binary fission is a simpler process that primarily occurs in prokaryotes and does not involve these complex regulatory mechanisms.
