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.

Answer:
a. add more of the enzyme
Explanation:
Enzymes have specific sites to which their substrates bind during the reaction. These sites are called active sites. When all the active sites of all the enzyme molecules present in a solution are bound to the substrate molecules, the enzyme is said to be saturated with the substrate. Under these conditions, more enzyme molecules are to be added to the solution to increase the reaction rate and to obtain the product at a fast rate. The addition of more enzymes will allow more substrate molecules to occupy the active sites and to be converted into the product/s.
Answer: Protiens help provide structural support for our metabolism, and they can act as enzymes, carriers, or hormones to help us. They provide growth and maintenence and also act as messengers for our brain. They bolster our immune system and also transport/store nutrients. Basically, they do a whole lot!
