What do we mean when we refer to a cell as differentiated?
Otrada [13]

Answer:

We mean that a cell changes to another type of cell.

Explanation:

<em>Stem cells </em>are a type of cell that has the potential to become a specialized cell, this change or differentiation, is possible thanks to the activation or deactivation of certain genes that promote (or inhibit) the expression of certain proteins that origins different types of cells (fmuscle cells, osteocytes, neurons). This differentiation happens when the cells receive cues internally ( through signals or contact between a group of cells and another or through transcription factors) or externally.

Then, a differentiated cell is a cell that had gone under the previously described process.

I hope this information is useful to you!

julia-pushkina [17]
These are some ways how scientists and engineers develop, use and refine models.

1. Imagine. They have to know what exactly trying to model. They have to imagine and brainstorm what are the things to be considered.

2. Reason. Next, they need to answer the questions brought  from their brainstorming. They need to be able to reason out.

3. Calculate and Predict. Once they know it, that's the time they can start modelling and calculate - and predict.
