Answer:

The disease is caused mainly because of the attack on the myelin sheath by own immune system.

Explanation:

The MS or multiple sclerosis refers to a possibly disabling disorder of central nervous system. In the condition, immune system fights against and destroys the myelin, that is, the protective sheath, which envelopes the nerve fibers. This causes problems of communications between the brain and the entire part of the body. Ultimately, the disease can result in deterioration or permanent destruction of the nerves.

The law of_____
Marta_Voda [28]

Answer:

The correct answer is - segregation.

Explanation:

The law of segregation states that out of two factors or alleles of a gene located in an organism, only one allele or factor is distributed to each sperm cell or egg cell (gamete) randomly, So, the segregation of the alleles are random and only one allele is distributed to each gamete according to this law.

The law of segregation helps in making a different combination of alleles in a particular species or population and leads to variation in genetics. It makes sure that traits distribute to each generation randomly.

Answer: To know if a document is a primary source, check to see when the document is published, if it is an autobiography of a person, a diary, a letter, or the documents happen at the time of the event.

The competition between two organisms can be seen if there is only 1 source of food or habitat space and they're competing against each other for the food or habitat.

There is cooperation between two organisms if they are helping each other with resources or alarming each other if there is danger.

Predation between two organisms happen when one organism hunts the other organism for food.
