The interaction between genetics and environment and how this affects behavior, resulting in individual variances, is of particular interest to behavior geneticists.
The environment in this context refers to every external, nongenetic component of our life, including prenatal nutrition and the people and objects in our immediate surroundings.
Chromosomes:
Each of our cells contains 46 chromosomes, 23 from our mother and 23 from our father. Chromosomes are complicated, spiraling molecules formed of DNA that resemble threads and contain genes.
DNA:
We have over 30,000 genes, which are DNA segments that, when activated (expressed), serve as templates for the synthesis of different protein molecules, which serve as the foundation for our physical and behavioral growth.
Genome:
The entire collection of instructions for creating an organism, included in all of its chromosomal genetic material, is called an organism's genome.
Gene:
Combinations of mutations at certain gene locations serve to distinguish us from one another. The majority of human features are not controlled by a single gene acting alone, but rather by a number of genes working together.

Answer:
Areas where the myelin sheath has degenerated
Explanation:
Multiple sclerosis is a disease of the nervous system where the myelin sheath is damaged, and impairs its ability of conducing signals in the affected nerves, causing serious deficiencies in many life aspects (movements, sensations, cognition etc).
Answer: They all survive in any environment.
Explanation: Protists have the ability to survive in any environment, even extreme environment. They can live in the ocean, desert or extremely hot environment, or even a extremely cold environment.
I'll explain why the others aren't correct.
Protists can be both unicellular and multicellular, they're not always unicellular. Kingdom Protista contains all eukaryotics, so they're not always unicelluar.
Protist cannot make or consume food. Animals consume food, and plants make food, not protista. Yes they're many plant-like protists out there, such as algae, they get their food from the sun above. So all protists cannot make or consume food.
Protist does have flagella, but not all protists. Protists that are motile and generate movement have flagella, meaning they move. Not all protist move, like plants can't move. So, not all protists have flagella, meaning they can move.
Let me know if you have any questions.

Amino acids are the building blocks that make up proteins.
