Mitosis y Meiosis

La mitosis es el proceso mediante en el cual una celula eucariota separa los cromosomas de su nucleo, dando como resultado dos juegos identicos. Estas se llaman "celulas hijas.
Sencillamente, la celula madre se separa en dos celulas hijas que son identicas a la celula madre. Esto se logra dividiendo el nucleo de la celula madre en dos partes. Contienen el mismo numero de cromosomas que la celula madre.
Se reproduce de forma asexual, esto quiere decir que puede lograr dos copias exactas de la celula original. Es un proceso eficaz, pero, no permite la diversidad ya que las copias son identicas.






 En cambio, la Meiosis es un proceso de reproduccion sexual. Es un tipo especial de division celular necesaria para la reproducion en las eucariotas.
Las celulas que resultan de este proceso son llamadas gametos o esporas. Los gametos son el esperma y los ovulos en su mayoria, comunes en plantas o animales.
Este proceso consiste en una celula que contiene dos copias de cada cromosoma, uno de la madre y otro del padre, produce cuatro células que contienen una copia de cada cromosoma. El resultado es una mezcla única de ADN materno y paterno. Esto permite que la descendencia sea genéticamente diferente a cualquiera de los padres. La meiosis introduce la diversidad genética dentro de la población.

 

The wall

“The wall” directed by Alan Parker is a movie reflected on Pink Floyd’s album “The wall”. The film is full of metaphoric views and also the representation of the “wall” itself.

The simbolism of the wall can be analyzed in different ways. During the years later to the appearance of “the wall”, the simbolism of this had changed a lot metaphorically.
Firstly, by a good of varied audiovisuals effects they try to represent Pink’s life. A life of a character that is situated in a point of no-return. A character that suffered several complications during his life. His father went to war, his mother self-protected him in a high level and this situations put Pink in a very isolated actitude towards the others and keep very in touch with his mother. Also, in “Another brick in the wall” Waters represent the system of education the character was having and we see how this affect his actitude because it was a very opressor system of mind “thought control”. Also, we could think about the wall been the system that control and impose ideas into the people. A big barrier between system and the people. Beside that, the wall is also represented when the double-hammer appear. The hammer is a strong object that can be used to build and also, to destroy.  After analizing this appearences in the movie, we could infeer that all this complications that Pink had along the movie act like a brick that serv him to build his own wall. Walls are made to separate, by this, Pink build this wall to isolate from the system and people. But this turn into a negative separation, because Pink start to feel sensitive.

“The wall is still a protest action” Claim Waters three days ago. He claim that during the years, people think that the wall was the story of Pink and his complications mention before. “It is much less about the history of Pink and his loss on the concern of all people who lose wars” Claim Waters in this note. This mean, that The wall is a piece to all the people that have any kind of trouble and want to get in touch with the songs and with it’s experiences through that. We could think, that, is something much general that someone loosing someone in the war.

In conclusion, we can afirm that the wall is a common wall filled with different problems (bricks) and all those problems became a barrier between the people and the system. And by this, in a way it creates a protest action by the people that is behind this big wall that is the system. A wall construct by the problem of any who could get in touch with this wonderfull movie and this wonderfull letters written by Rogers Waters.

The happiest day of our life

Listening to the song "The happiest day of our life" we can infer by the letter we can understand that teachers are painfull when they are in school but when they reach home they are a muppet. So, we can infeer that the teachers veint their anger that brought home into their students

When we grew up and went to school

There were certain teachers who would

Hurt the children in any way they could

By pouring their derision upon anything we did

And exposing every weakness

However carefully hidden by the kids

But in the town, it was well known

When they got home at night, their fat and

Psychopathic wives would thrash them

Within inches of their lives

Another brick in the wall

While the song is not the first example of the antieducation theme in popular music, it comes at a time when increasing numbers of students are questioning the value of their education. Thus, young people are responding to the song with uncommon — and unsettling — enthusiasm.

In May [1980], the South African government banned the song — and the album — "because "Another Brick" had become the anthem of a national strike of more than 10,000 "coloured" (mixed) students and their white supporters. The students had been protesting the inequality of spending on education for the various races, as well as "intimidation" by teachers, whose authority the Pink Floyd song challenges. The government ban forbids radio stations to play the record, stores to sell it, and individuals to own it.

In my opinion, I think education must be the first and most important issue in every person, but one thing is a good system of education and another thing is a bad system of education that controlls and hurt physical and mentally the students. The term “we don’t need no education” can be analyzed in two parts. One is that they don’t need THAT education, this mine, that type of education (opressive, controlative) and the other part is, that kids must not have an education system, that, in my opinion, here is not the message they want to transmit, if not, they want transmit that they dont need an education that becames a no-education.
