What do you know about cell differentiation in multicellular organisms? Check all of the statements that are true.

Proteins play a key role in cell differentiation.
The external environment, specifically temperature, during the development of turtles and some other reptiles helps to determine the sex of hatching offspring
Different transcription factors are associated with the differentiation of stem cells into bone, muscle, and nerve cells.
Transcription factors bind to regulatory regions of a gene and affect their expression.
The amount of available light or daylength helps to determine the patterns of gene expression that lead to flowering in some plants.

Respuesta :

All of them should be checked

Answer:

All statements are true.

Explanation:

Cell differentiation may be defined as the process at which the cell divides to stop and each cell determine its fate to perform a specific function. Cell differentiation requires specific transcription factors.

Most of the transcription factors are made of protein and provide play important role in cell differentiation. These transcription factors are important for the formation of bone cells, muscle from the stem cells. They binds to specific region of gene and starts transcription. External environment like temperature play an important role in determining sex in case of some reptiles. The flowering of some plants depends on the specific amount of light they receive.

Thus, all statements are true.
