There's no oxygen in space but we all breathe. The sun has enough gravity to keep the oxygen inside it just like Earth but even more so. However this oxygen isn't for burning like we would burn wood. It is part of the cycle of nuclear reactions going on in the sun. The gravity of the sun is large enough to keep the mass of gas concentrated enough to be able to sustain such nuclear reactions.

No space suits are worm, infact tubing has to be run inside the space suit with water running through it to keep the astronaut cool. A space suit is like a mini space ship, it is completly closed from space and there is now were for your body heat to go.So without the water filled tubing you would cook in the suit.

Yes, of course there is litter in space, AKA "space junk".\nStuff does get lost durring space walks, stuff will fall off a satelite, debris is in orbit around the Earth.\nAll that space junk is being tracked in its orbit along with all the other satelites and space vehicles since they pose a collision threat.  You need to know where all the potnetially dangerous stuff is up there when you launch something in to space so you dont put in on a collision course.\n\nEventually, all the stuff will burn up in the Earth's atmosphere after its orbit degrades.

Astronauts will not "explode" if their space suit depressurized. If you've ever seen how things act in a "vacuum" bell jar, it explains what would happen: liquids boil at lower temperatures at lower pressures, thus the liquids in the astronaut's body would vaporize and thus the astronaut would be killed (no blood=no oxygen to the brain, for example). Their body would remain intact because skin and other body parts are essentially solids.

After eating, astronauts settle down to the assigned tasks of the day, either supervising experiments or performing routine maintenance on station equipment. It takes a complex array of machinery to keep people alive and well in orbit. Daily, each human breathes the equivalent of 0.9 kg. of liquid oxygen - enough air to fill a 3.5 cubic metre room - and drinks a total of 2.7 kg of water. To minimize on resupply needs, the ISS life-support systems are designed to recycle as much as possible. Waste water from urine and moisture condensed from the air is either purified and reused direct, or broken down by electrolysis to provide fresh oxygen. Carbon dioxide 'scrubbers' chemically remove that toxic gas from the air.

<Bears eat both meat and vegetation.They are mainly omnivorous(eating both animal and vegetable foods), \n although some have a more specialised diet, such as polar bears. They eat lichens, roots, nuts, and berries. They can also go to a river or other body of water to capture fish.Polar bears are the largest type of bear, indeed one of the largest carnivores on terra firma. Sun bears are the smallest, only a bit smaller than the average woman.

Fish! Trust me it is full of protein and good "brain food".\n\nTry eating a Tuna and salad sandwich... hopefully you like tuna :)

Space is a unique environment. Orbital velocities alone provide risks of collisions with dust as well as many kinds of Solar radiation.\n\nAn astronaut would probably not encounter a solar flare directly. However the radiation and ionic streams that are streaming out from these storms often pass by Earth.\n\nWe, on Earth, are protected from most Solar radiation. We experience it as the Aurora or Northern Lights. On Earth we experience the harmful effects of ultraviolet radiation. Most radiation, however, is screened out by the magnetosphere or atmosphere before it can reach the Earth's surface, and the life thereon.\n\nAn astronaut is only protected by his vehicle and his clothing or space suit. These are good at protecting astronauts, but astronauts are still in far more danger than his fellow humans on Earth.\n\n;-D We should all be thankful that courageous men and women do brave deeds that benefit all mankind.

Many things are in space...the are compounts of gases, metals, rock and ice...Elements you can find on earth too

No, they have a special bathroom\nI looked it up for you on the web\n\n4. HOW DO ASTRONAUTS GO TO THE BATHROOM AND TAKE CARE OF OTHER PERSONAL HYGIENE? \nEach Space Shuttle has a toilet that can be used by both men and women. Designed to be as much as possible like those on Earth, the units use flowing air instead of water to move waste through the system. \n\nSolid wastes are compressed and stored on-board, and then removed after landing. Waste water is vented to space, although future systems may recycle it. The air is filtered to remove odor and bacteria and then returned to the cabin. \n\nAstronauts brush their teeth just like they do on Earth. There is no shower on the Shuttle, so astronauts must make do with sponge baths until they return home. \n\nThe toilet that was first flown aboard STS-54 is completely new in design and offers new and improved features: \n\nThe new toilet features better hygiene, larger storage capacity, greater dependability, and an overall cost savings in maintenance. \n\n-The previous model had a 14-day capacity for storage of waste material. The new model has an unlimited storage capacity. \n\n-The new model features a cylinder system where a plastic bag is placed in the toilet before use. The bag is then sealed and is forced to the bottom of the cylinder after each use by a plunger attached to a lever. A new bag is then placed in the toilet for the next astronaut. When the cylinder is filled, it is replaced by a new cylinder. \n\n-The previous model relied on air flow to pull the waste to a holding tank. None of the waste was separated as it is now. The new system provides better hygiene conditions. There was no way to empty the old system. When it was full, it simply could hold no more waste materials. It had a 14 day capacity. \n\n-The new toilet also provides an odor-free environment. The old model did not. \n\n-The opening in the lid of the toilet was increased from 4" to 8", allowing for easier handling of the plastic storage bags. \n\n-The urine collection system was also improved. A newer type of fan system is being used to force the urine to a holding tank where it is periodically ejected into space, where it vaporizes. \n\n-The previous system had trouble with corrosion in the fan system. \n\n-The new toilet can be cleaned without removal from the orbiter at the completion of the mission, reducing the cost of servicing. \n\n-The previous system must be removed and sent to a company in Houston, Texas for servicing.
