Benefits with dogs  of living

Today we are talking about the benefits of living with a dog. We have observed the difference between people that have or not a dog.  
At present research was done on everything, the last ones related to the benefits of having a dog is that they detect skin cancer (and some can also detect bladder, lung, breast, ovarian and colon cancer) 

 Besides that  have demostrated that dogs increase immunity because they have more bacteria, both home and owners are exposed to these bacteria but over time they become immune to them. 

Enjoy with Sciencie

           

Experiments

For breaker the belief of the sciencie is borring or very difficult, we teached some experiments what you have in home and the materials is very easy find.

First,  we give you the definition of experiment: 

A experiment is a test or exam you make when  prove the element or you want evidence the determinade caracteristics.

example:

crystal ice

materials
1 deep plate
6 paperclip
1 jar
1 espoon
1 pencil
sugar
litter thread

procedure:

firts: put hot water on the jar, next add six spoon sugar
secon: mix the sugar let cold
third: the paperclip hook on thread,

Extinction of snakes

Extinction of snakes 

The rattlesnake is considered an endangered species, and could disappear if the necessary measures are not taken.

The peasants usually kill this species to protect the family and animals they have, sometimes the snake is trapped by people to offer their skin, sell them for pets, process their meat for medicines, among other actions.

One of the characteristics of the viper is that they can find themselves calm and suddenly attack in a matter of seconds and although they can be mortal, they only attack in the perspective of danger.

The most venomous snake in the world is The King Cobra, has many people worried about their appearance and size, are responsible for many deaths. When a snake bites a person, medical treatment is important, as that bite becomes infected and can lead to death. There are subspecies of cobras, but this is the largest, grow up to 18 feet and a half, however, in many places are 12 feet long, when fully developed weigh 13 pounds, males tend to be thicker and be longer, also have a large and wide head.

DEFORESTATION - Daniel Benitez, Sergio Suaza. 1104

DEFORESTATION

the felling of trees is a man-made action on nature, in this case exhaustive logging, deforestation devastates the forests of the Amazon, massively causing catastrophes at the level of the animal ecosystem, loss of biodiversity and the quality of soils

or urban use. The most concentrated deforestation occurs in tropical forest. About 30% of Earth's land surface is covered by forests.

Deforestation In Colombia:
Causes: 

Deforestation in Colombia is mainly targeted at primary rainforest which covers more than 80% of Colombia. This has a profound ecological impact in that Colombia is extremely rich in biodiversity, with 10% of the world's species, making it the second most biologically diverse country on Earth.

One of the main causes of deforestation in Colombia is the national Plan Pacifico which is intended to raise revenue to develop the economy. The plan includes exploitation of Colombia's rainforests for the extraction of precious natural resources for exportation

Effects: 

"Deforestation has been responsible for the erosion of riverbanks which have affected the levels of river beds, which has had negative effects on aquatic life and fish stocks as well as on transportation and navigation because of silting. This forest clearing also accounts for great habitat destruction for creatures dwelling in the Columbian forests. For example, the cotton-top tamarin is considered to be critically endangered, and ranks highly on the list of "The World's 25 Most Endangered Primates." Habitat destruction through forest clearing is the main cause of this collapse, and cotton-top tamarins have lost more than three-quarters of their original habitat to deforestation.Local initiatives, like Proyecto Tití for cotton-top tamarins, have been created to raise awareness of such cases."

Personal Opinion Of The Problematics:

To our way of seeing in the matter with the matter of the deforestation it is a problematics of supreme importance since this felling provoked by the hand of the man to obtain agriculture, ranching and mining industry are a Viennese needed but that eventually it is a way of destroying our environment.

Topicality:

At present the great majority of deforestation is given in Latin America, Western Africa and some regions of Asia, the reason or one of the major reasons of these events there are excessive gentle projects given by diverse industries and companies that only seek to be increased,for example in Brazil the deforestation in 2017 increased in 28 %, with more than 5 thousand square kilometres of felled trees, this and many more sound examples of which many persons not estan informed and that they affect any alive being who lives this place.

EFFECTS OF ALCOHOL ON THE HUMANS BODY

BY: KEVIN RAMOS

               SEBASTIAN RODRIGUEZ

During these holidays, alcohol abuse is very common, causing considerable damage to our body. 

•  the brain: too much alcohol inhibits the functions of the frontal region, thereby decreasing memory, concentration and self-control.
• the kidney: it removes more water than it takes in and causes the body to look for it in other organs.
• the heart: the effects of alcohol cause an increase in the cardiac activity and acceleration of the pulse.
• the stomach: alcohol increases acid-rich secretions and improves digestion, but when drunk excessively causes erosions in the mucosa of the stomach produced by ethanol, the main component of alcohol.

Effects of alcohol in the young people:
Drinking alcohol during adolescence has many risks. Some of them are direct because the consumption of alcoholic beverages is dangerous for health. Other risks in the case of adolescents are indirect and are linked to the behaviors derived from alcohol consumption.

Indirect Risks:
The consumption of alcohol causes important effects on the behavior, effects that can produce very serious problems.

• Unwanted pregnancy and sexually transmitted diseases: Lack of self-control that causes alcohol can lead to sexual intercourse without adequate protection.

It is one of the most devastating meteorological phenomena as they are able to destroy large areas and territories reaching speeds that can exceed 250 km / h. There are numerous factors that influence the occurrence of hurricanes, from the meteorological phenomena, through the regions in which they originate, to the very structure of the hurricane. But only the tropical cyclons that are form in the Atlantic Ocean and the eastern Pacific Ocean are called "hurricanes."

How do hurricanes form?

The hurricanes form for the collision among the hot air and the wet air on the Equator.


Wich are the most hurricanes famous?

The hurrican Jeanne in 2004, this caused five deaths, 

plastic island

Plastic Island

Santiago Andres Andapiña Lombana

Juan Esteban Ramirez Valdivieso

This island is situated in pacific ocean near to the coast of Chile and is created by humans thanks to the tons we throw every time to the rivers and the streets.

It is very important to know about of the plastic island because is causing many problems in the world on a political and mainly ambient level because change every sea ecosystem and this generate many death of every marine life.

The marine life is composed by small fishes, sharks, seaweeds, coral and other species that are essential for the human life considering that serve as a food, generate oxygen and a dress
