My favorite animal

My favorite animal is the dolphin. They are the one of the most intelligent animals in the animal kingdom, they have many features in common with humans like the communication with others dolphins by means of the echolocation, they are able to solve problems, they live in family groups and when other member of the family is wounded the others dolphins help him even if he needs breath.
They have a fusiform body adapted to swimming fast, the tail fin, called flow, is used for propulsion, while the pectoral fins are used for directional control of swimming. They possess in the head the melon, a spherical organ used for echolocation. Their brain is large with well developed cerebral cortex compared with the average of mammals
In their first months of life they are feed for breast milk because they are mammals and then they eat fish and squid. They live in all oceans except in the cold waters of the poles, they are relatively close of the coasts and often interact with humans.
I like this animals because they are very similar with us in many features and because they help the others members of their family. Maybe they are more intelligent than us and we have not even noticed.

Public education in Chile

This is a topic has long been talking and little or nothing has been done, the changes i have seen since this fight began have been increasing scholarships from the state and they reduce the percentage of 6% to 2% of CAE, for the people go into debt but not as much as before.
And now in the congress are evaluating education reform.
Sincerely i think that this is a problem in the long period and not in a short period, mainly the changes i would make would make first remove the PSU because it is not a good system to select who can and who can not go to the university and then i would give public education to the people who really deserve and made and effort in the school, because none of us wants a son of a businessman study free if we all know that her father can pay the university and another person can not study because he or she can not pay the university. I think that this problem have much more time for debate in the country until before arriving at an answer.
 

Why do I want to be a vet

Since i remember i always want to be a vet, my mom and grandparents say when i was 5 years old they asked to me what i wanted to be when i was more adult and i always said veterinary, I always felt a love for the animals and whenever i saw a animal in the street i felt sadness for they and i wanted help.

At first i didn´t have others options of careers to study, but my mom always said me that in case that i couldn´t study veterinary, i had other options so i chose agronomy and engineering in environment, because those careers are related with the environment and also with the animals.
How i said y always want to be a vet, the reasons are that i like very much the animals and i feel the need to help them and protect the animals to other humans.
I had a good experience in the university because the people are here for a common interest so i can talk with them how is the career or i want to specialize, but i didn´t like being so long without classes.
I would like to work directly with the animals like the study of  their behavior or with exotic animals in a zoo or something like that.

Three videos

In this video you can see how a plant grow since it is a germ until a large plant, you can see a time-lapse because this process take some days.
I like this video because we never think in this, how a little germ can be a large plant and i think it is so interesting know about how born a plant because they are part of our ecosystem.

In this video you can see the transformation of a butterfly since she/he is a larva then it transform in a cocoon, and finally go outside a beautiful butterfly.
I choose this video because it is so interesting see all the changes that has this animal before be a butterfly and in the way it does because it is not very simple

This video show how a cat is hunting a rabbit since the cat is approach with caution for not be detected for the rabbit.

I think this fact are not only in the jungle, this happens every day in the city because this animals need to hunt their food also the cat is very intelligent because it is walking with very caution for not miss his prey
