Ans.
Hormones are regulatory substances synthesized by various plants and animals and play role in proper growth, development, and maintain homeostasis. Hormones are released by signalling cells and show their actions after binding to specific receptors present on the surface or inside of the target cell.
Hormones, for which receptors are present inside the cells (in cytosol or nucleus) should be hydrophobic in nature. This is because plasma membrane is made up lipid molecules and small, hydrophobic, uncharged molecules can easily pass through this. For example, cortisol, estrogen, and progesterone hormones are lipid-derivatives and receptors for these hormones are present inside the cells.
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.

<span>Answer:
Set point theory suggests that our body has a particular range of weight that it is comfortable in, usually about 10% of a body’s weight. That means, if you weight 175, you have about an 18 pound range; if you weigh 325, you have about a 33 pound range. Most people lose and gain within this set point on a pretty regular basis. They may put on a little weight in the winter and lose it in the spring. Or get busy and drop a little weight. Or gain a little when stressed. Or lose a little during an illness. Or whatever. Movement within this range is normal. However, movement outside of that range is not. In fact the body seeks homeostasis – that is the body seeks to stay within that range. To move outside of that range something must go on, something must happen to the body.</span>
