The entire life cycle of a monarch butterfly is only about six to eight weeks. The chrysalis stage lasts about ten days.
Active immunity is acquired from vaccinations or from infection against a pathogen. The next time you encounter the same pathogen your body has built memory against it and will be able to fight it much more efficiently. Passive immunity is primarily through a mother to a baby or fetus. Through the placenta the mother transfers her immunity (IgG antibodies) to her fetus. Also through breast milk she can although the placenta is much more so. The baby has her/his immunity from the mother but it only lasts a few months because the baby hasn't developed his/her own immunity.
The difference between humoral immunity and cell-mediated immunity is that humoral immunity uses B cells and T cells whereas mediated immunity only uses the T cells. Also humoral immunity provides a defense against antigens and pathogens in body fluids whereas cell-mediated immunity protects from abnormal cells and pathogens inside living cells.
Because adolescence, by definition, only lasts for 5-10 years, while a personality disorder, by definition, lasts for a lifetime.

Yes, unless it is taken away by some rule, act or law. But, there is a caveat on this; that the immunity only exists when they are traveling to, or from, the capitol (generally speaking). It is interesting to note, that in many states this same immunity exists when a voter is traveling to, or from, a polling house (place to vote).
Active Immunity - Vaccines are used for health purposes to expose our bodies to a particular antigen. These antigens are usually killed or severely weakened to decrease their potency. After destroying these pathogens, the body stores some T cells as memory cells, due to the fact they code for a particular antigen and can be when needed. This memory in T cells can be a means of artificially acquiring immunity while a genuine attack by a pathogen is a naturally acquired type of immunity. Passive Immunity - This is where immunity to particular antigens as a result of genetic traits passed on from parents rendering the offspring immune to a particular pathogenic threat.

All you have to do is put food colouring in the chicken. This only works with white or pale coloured chickens, and lasts only a few weeks.
