I believe 38 weeks is term for twins and I was lucky to get to 38 weeks. My doctor mentioned getting to 32 weeks a lot throughout my pregnancy. I think the babies will do much better if you make it to 32 weeks so everyone breathes a little sigh of relief when you get to that point. believe 38 weeks is term for twins and I was lucky to get to 38 weeks.

Earth, our home, is the third planet from the sun. It is the only planet known to have an atmosphere containing free oxygen, oceans of liquid water on its surface, and, of course, life.
In our solar system we, Earth have a lot of oxygen, Astronauts are trying to find out any more habitable planets we can live on. But there is no other planet with the same atmosphere as Earth.nly trace amounts of oxygen exist on other planets. Earth is unique. The atmosphere of Earth is said to be out of equilibrium. This is because oxygen does not remain as a free gas very long-it is too reactive.
