The positive effects were that they were allowed to easily assimilate and become a part of the American society according to American traditions. They were given all rights that all other citizens of the United States had which meant that they could vote or purchase property or anything similar.
The negative effects are that in assimilating them they would often abandon their own culture in order to adapt so they were not included as so much as assimilated. The idea was not to make the two cultures co-exist, but rather have the Native Americans become like the everyday US citizens.
They all wanted to paint the ideal human form in it's perfection. They believed that understanding the human anatomy would help them with this.
It really depends on which state you live in. Some state it is easy to amend their constitutions while with others the process is difficult.
To change the US Constitution you need a 2/3rds majority from Congress. I believe with state constitutions you have to have a petition with a certain number of signatures, which is hard to do, then the signatures must be checked to make sure they are authentic meaning the people who have signed the petition are from the state and they actually exist. Then it goes to the State, which they will look at the petition and I believe the State gives it to lawyers too look at and then a Judge must also look at it. If the judge disagrees, the process must start all over again.
Hopefully this helped and good luck.
