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.

Hello again!
If plants are purebred, then they are homozygous. This means that they have the exact same genes in one pair: for example, AA. If they are both purebred, then the dominant gene will win out every time. The answer for this question, then, would be D. Here is a diagram to help you!
Answer;
- A sense
A sense is a system that translates data from outside the nervous system into neural activity, thus giving the brain information about the world.
Explanation;
-The sense or sensory nervous system is a part of the nervous system responsible for processing sensory information.
-A sensory system consists of sensory neurons, neural pathways, and parts of the brain involved in sensory perception. Commonly recognized sensory systems are those for vision, hearing, touch, taste, smell, and balance.
-Senses are transducers from the physical world to the realm of the mind where we interpret the information, creating our perception of the world around us.
Answer: this is called passive transport and it does not require energy.
