Identifying the genetic sex of a child is based on finding intracellular Barr bodies that consist of inactive chromatin material.
Inactive chromatin material is the one where no transcription takes place. It is also known by the name heterochromatin. It appears as a dark condensed form in the chromatin.
Barr bodies are the inactive X chromosomes. These are mad inactive by a process termed as lyonization. It is essential to make the chromosome inactive in organisms with XY type of sex determination. They are present at the periphery of the nucleus. Inactivation of X chromosome makes the amount of X chromosomes equal in both, males and females.

When you have atoms they can’t touch each other like the body can’t touch anything so no they won’t be solid
Pretty sure it’s all of the above
<span>d. Adult stem cells are multipotent and can differentiate into types of cells
Stem cells are specialized cells that do not have a particular function nor structure on its prior form. These cells can be associated to be replacement cells or new cells depending on its type.
The adult stem cells are not multipotent and can only transform into some cell types..</span>
