Answer:
Maybe it is 5.50 because not much information is given to calculate it or to find it.
The right answer is: The antibodies mistakenly identify the cells as foreign material.
The role of an antibody is to recognize a foreign antigen in order to neutralize it. They can achieve this thanks to the great specificity of their paratope, which recognizes only a very precise part of the antigen: the epitope. As soon as an antibody recognizes an epitope, the B lymphocyte that codes for that specific antibody multiplies and matures in order to synthesize the same antibodies, useful in large quantities.
The phenomenon described in the question is an autoimmunity mediated by autoantibodies.
An autoantibody is an antibody produced by the immune system and directed against one or more proteins of the individual himself
Many autoimmune diseases are due to the presence of these autoantibodies, but the presence of autoantibodies is not necessarily synonymous with such a disease.
Some scientists say that they could have a beneficial role in cleaning up cell debris resulting from a disease.
The way in which these autoantibodies are produced, their precise role, and the reason why they decrease in individuals with certain diseases, are all issues that remain unresolved.
Answer:
The correct answer is c. are as genetically similar as other siblings.
Explanation:
Dizygotic twin are the twins which developes from two different fertilized egg. So a dizygotic twins can be both male, both female or one male and one female. As dizygotic twins are produced by fertilization of two different gametes, therefore, they share just half of their gene like other siblings share.
Therefore dizygotic twins are as genetically similar as other siblings. Monozygotic twins are the twins that are produced from a single fertilized egg which splits into two eggs. So monozygotic twins share 100% gene, therefore, they are called identical twins. So the correct answer is c.
