Answer:
the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
Most likely located in the nucleus, mitochondria and chloroplasts! The nucleus contains the most DNA!
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:
predation
Explanation:
If the first coat color is black for example, the mice will be able to hide away in a dark area or corner, they will also be able to move around at night almost undetected. Changes in environment, such as development and introduction of street lighting may cause these mice to be easily seen by predators. These mice will quickly be eaten by predators now that they are accessible. On the other hand mice that have a different color such as white or grey will be able to blend in better with the new surroundings. These mice will pass along this trait to their progeny and the new coat color will proliferate.
