Where does it come?

                      ALHAURIN DE LA TORRE WATER.


The water  provided to Alhaurín come from diffrents from where are placed at different parts of the town, the most known is los Manantiales, but there are others like El Romeral or Trorresol. The water of Alhaurin is considered one of the best, because it has high quealities and it is good for our organism.

Detractors of Al Gore.

Most of Al Gore's detractors are members of the government who disagree de Al Gore's point of view. They think that he is a liar and the government believe that the money that have to be used to the global warming is used in other thingst. They accuse him of using climate change to profit himself

Antartic today.

Antarctica is therefore one of the few places in the world that can truly be described as having been discovered, rather than already people living there already who had "discovered" it long before.
No-one lives in Antarctica indefinitely in the way that they do in the rest of the world. It has no industries, no towns or cities, or permanent residents. The only "settlements" with longer term residents (measured in months or more) are scientific bases.
In the last years the Antarctica is suffering a lot of changes due to the global warming, the temperature is incresing and it produces the melting of icebergs. This melting affects the habitats of living beings that make their lifes there.

Molecular diseases: mutations.

                                          MUTATIONS. 


In genetics, a mutation is a change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal genetic element. Mutations result from unrepaired damage to DNA or to RNA genomes (typically caused by radiation or chemical mutagens), from errors in the process of replication, or from the insertion or deletion of segments of DNA by mobile genetic elements. Mutations may or may not produce discernable changes in the observable characteristics (phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes, including evolution, cancer, and the development of the immune system.

Insertions: occur when extra DNA is added into a existing gene.

Deletions: remove information from the gene. A deletion could be as small as a single base or as large as the gene itself.

Frame shift: mutations result from either addition or deletion of one ot two nucleotide bases. When this occurs the ''reading frame'' is changed so that all the codons read after the mutation are incorrect, even though the bases themselves may be still present.
