Because an antibody is "made" relative to the antigen, but kept at low levels when you are exposed the first time ("primary immune response"). The second time you're exposed to the same antigen, memory cells recognize it and the body produces a high level of antibodies, and the level of antibodies usually remains higher for a longer time ("secondary immune response"). This is your basic immune response (primary and secondary).
This explains exactly why vaccines are effective to extremely effective.
Through reproduction. dark fur is a dominant trait and eventually if offspring of the one dark furred mouse reproduce enough, it will eventually spread to the whole population because it is a dominant gene and will overpower recessive genes of the other parent organism that the dominant mouse is reproducing with.
Answer:
The diagram is attached below.
Explanation:
when sodium and chlorine comes close together they form anion and cation. The compound formed is called sodium chloride.
Both atoms bonded together through ionic bond.
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
Answer:it is a
Explanation:because it just makes sence.lol
Answer:
Somatic mutations are mutations that occur in body cells, that is the cells that do not make gametes. These mutations are not passed on to further generations; for example, if a mutation that changes a gene in a skin cell would not affect your children because skin cells don't produce gametes.
