CAN A SPACESHIP GO THROUGH JUPITER ?

Despite of its bad reputation ,jupiter olsa called ``the giant planet of gas ´´its clauds hides a big nucleus made of rocks 20 times more solid than the Earth .This nucleus bloks any posibility of crossing the centre ,but even visiting the clouds could finish really bad .

We don´t know a lot about the interiors of these planet but all we know about these planet is thanks to the sounding line called Galileo. All what we know is: in first place, every spaceship has to cross the radiation belt of Jupiter, that it will dislocate  its instruments. Then it will have to face with very strong winds of 370 km/h. And if exist more posiblities, it will come gusts of about 650 km/h. In the external atmosphere  the temperature medium is of 152 ºC, but it could reach 27.760 ºC near the nucleus.

Between the atmosphere and encandescent nucleus, the interior of Jupiter is formed of metalic hidrogen, in liquid state. It consist in a conductor that only can exist in the conditions of these planet with a presure of almost 3 millions of kilometres per cm2.

These is why a spaceship can´t go through Jupiter

 

Is healthy to eat genetically alterated fish?(By JORGE TELLADO)

Is healthy eating genetically alterated fish?

•Genetically alterated fish are organisms from the taxonomic clade which includes: jawless fish, cartilaginous fish and bony fish whose genetic material (DNA) has been altered using genetic engineering techniques. In most cases, the aim is to introduce a new trait to the fish which does not occur naturally in the species.

•Genetically alterated fish are used in scientific

research and kept as pets. They are being use in

aquaculture food production. Some genetically alterated

fish that have been created have promoters driving an

over-production of "all fish" growth hormone, including

salmonids, carps and tilapias.

•Critics have objected to genetically alterated fish on

several grounds, including ecological concerns, animal

welfare concerns and with respect to whether using

them as food is safe and whether genetically alterated

fish are needed to help address the world's

food needs.

COULD CROCODILES LIVE IN THE ARCTIC?

COULD CROCODILES LIVE IN THE ARCTIC? 

  

This was the arctic millions of years ago

Yes, crocodiles could live in the arctic, but it isn´t because they can survive in cold temperatures, is because in the past, 55 millions of years ago, the arctic wasn´t cold, so they could live there.

Nowadays they can´t live in the arctic because they have cold blood, so they have critical body-temperature limits within which they can survive.

The Intergovernmental group of experts about the Global warming calculates that the average temperature of the air in the Earth will raise 6.4ºC at the end of the 21st century, so in a future, is probably that crocodiles could live in the arctic.

Why does the `Titan arum` (corpse flower) smell so bad ?

The corpse flower is one plant that have the worst smell .

This species is native to the rain forests of Sumatra ( Indonesia) , and in addition to its extraordinary size , has another feature that makes it unique : gives off a foul smell of rotting flesh , which prevents be near her for long. For this reason it has been called " corpse flower " . The function of this unpleasant smell is to attract pollinating insects to take charge of the exchange of pollen necessary for reproduction ; attracts flies looking corpses which lay their eggs , the larvae will then saprophagous . It is an herb that can exceed 3 m in height. It has a surface tuber, which flows a single stem up to 1 m long, which in turn presents a single leaf and flower stalk . Its flowering is an event, it only makes three or four times in the forty years that usually live plant . Once the inflorescence begins to appear , growing at a rate of 10 cm a day to an average of 2.50 m in height, about 1 m in diameter and weighing 75 kg . After this, the flower only live for 3 days.

The main factor is the heat . The energy obtained by photosynthesis is not used to make food but to release heat in a process called mitochondrial uncoupling . This additional heat ( haseta reaching 37.8 ° C) is released by the tip of the plant (which reaches up to 2.7 m high). then producing the so-called chimney effect : thus heat causes more volatile aromatic compounds and may further spread around.

The compounds that cause this putrid smell are molecules containing sulfur , such as putrescine and cadaverine calls , along with compounds such as trimethylamine , which is the same substance that gives its fresh fish smell soon No one knows exactly what chemical elements are responsible for the smell rotten corpse flower .
