THE HUMAN RESPIRATORY SYSTEM:

Humans need a continuous supply of oxygen for cellular respiration, and they must get rid of excess carbon dioxide, the poisonous waste product of this process. Gas exchange supports the supports this cellular respiration by constantly supplying oxygen and removing carbon dioxide. The oxygen we need is derived from the Earth's atmosphere, which is 21% oxygen. This oxygen in the air is exchanged in the body by the respiratory surface. In humans the alveoli in the lungs serve as the surface for gas exchange. When we Inhale we breathe air and when we Exalead we thorw carbon dioxide.

GRAVITY

THE GRAVITY WAS DISCOVERED BY ISAAC NEWTON, IT IS A FORCE OF ATRACTION AND IT MAKES THAT THE THINGS SEEMS TO BE ATRACTED TO THE GROUND, BY THE MATTER, BECAUSE IT MAKES THAT GRAVITY WORKS.

THE GALAXIES PRODUCE GRAVITY, EXAMPLE: THE SUN AND THE PLANETS PRODUCE GRAVITY, BECAUSE THEY ATTRACT EACH OTHER.

HERE IS A VIDEO ABOUT HOW THE WATER MOVES WITH ZERO GRAVITY.media type="youtube" key="r7fEHYkGxd0" height="344" width="425"

= Continental drift = The Continental drift was the movement of how Earth’s continents formed and is a hypothesis created by Abraham Ortelius in 1596 and was fully developed by Alfred Wegener in 1912 and also it was related with the theory of plate tectonics in 1960. The hypothesis said that all the continents we know today were joined in a supercontinent called Pangea and also that it happen 225 million years ago. About 200 million years ago, all of Pangea broke into two big continents: Gondwana (Southern hemisphere) and Laurasia (Northern hemisphere). Then Gondwana and Laurasia broke into smaller land masses, forming the continents we know today. Since the continents are still moving, you might infer that the surface of earth will be very different 200 million years from know. The Atlantic Ocean is getting wide, pushing Europe and North America apart. The Pacific Ocean is getting smaller and Australia is moving north. media type="custom" key="2520003"

= Earthquakes = An earthquake is a shaking of the ground caused by the release of energy in Earth’s crust. The energy is released by the plates crush together. More than a million of earthquakes occur each year. However, most are too small to be felt or cause damage. Earthquakes send out energy in the form of sismic waves. Scientists measure and record sismic waves on an instrument called seismographic. media type="custom" key="2520425" Source of information: [|www.en.wikipedia.org] Student: Andres Chavez Teacher: Mr. Gerardo Lazaro Grade: Middle Sixth “A”

GALAXIES THERE ARE 4 TYPES OF GALAXIES: 1. THE IRREGULAR GALAXY THEY ARE REALLY IMPORTANT BECASE THEY ARE THE ONLY ONES THAT DOESN'T HAVE ANY TYPE OF FORM LIKE THE SPIRAL, EPILLECTICAL AND BARRED HAD. SOME IRREGULAR GALAXIES ARE TINY SPIRAL GALAXIES BY ANOTHER GALAXIE NEAR, WITH MORE GRAVITY. THERE ARE TWO TYPES MAJOR TYPES OF IRREGULAR GALAXIES: AN IRR-I GALAXY **(** IRR L) IS AN IRREGULAR GALAXY THAT FEATURES SOME STRUCTURE BUT NOT ENOUGH TO PLACE IT CLEANLY INTO THE HUBBLE SEQUENCE. 2. THE BARRED GALAXY A BARRED GALAXY IS THE ONE THAT HAS A CENTRAL BAR-SHAPED STRUCTURE COMPOSED BY STARS. EDWIN HUBBLE CLASSIFICATE SOME TYPES OF BARRED GALAXIES: "SB" ("SPIRAL", "BARRED") IN HIS HUBBLE SEQUENCE THEY ARE LIKE OPEN ARMS. SBM (MAGELLANIC CLOUD GALAXIES), WAS SUBSEQUENNTLY CREATED TO DESCRIBES SOMEWHAT IRREGULAR WAS SUBSEQUENTLY CREATED TO DESCRIBE SOMEWHAT IRREGULAR BARRED SPIRALS.

3. THE SPIRAL GALAXY SPIRAL GALAXIES ARE NAMED LIKE THAT BECUSE, THEY HAVE SPIRAL FORMS ANDTHEY ARE BLUGDE INTO DISK. THAT GALAXIES ARE SUROUNDED BY HALO STARS AND RESIDE OF GLOBULAR STARS. TOGETHER WITH IRREGULAR , SPIRAL GALXIES MAKE UP APPROXIMATELY 70%. THEY ARE MOSTLY FOUND IN LOW-DENSITY REGIONS AND ARE RARE IN THE CENTER OF GALAXY CLOSTERS.

4. THE EPILECTICAL GALAXY

A ELIPTICAL GALAXY IS THE ONE THAT DOESN'T HAVE ANY ANGULAR MOVEMENT. SOME SCIENTISTS FOUND SOME BLUE STARS YOUNG THAT ARE IN SOME EPILECTICAL GALAXIES AND WITH OTHER STRUCTURES THAT CAN BE FUSED WITH THE GALAXY. THE EPILECTICAL GALAXIES WHERE FORMED BY A REALLY BIG GROUP OF STARS THAT WERE CALLED SECOND TOWN. THE ELIPTICAL GALAXIES MOSTLY ARE FORMED BY GLOBULAR STARS.
