How is krypton important to humans?

It isn't particularly important, except for making neon signs.  Krypton is also sometimes used for filling the space between panes of double-pane glass.  Xenon, which is rarer, is more important because it is used for making flash tubes and the new HID headlights.

As a practical matter, it is impossible.  If the model is the size of a basketball, the nucleus would be a point in the center too small to see, and the electrons would be modeled as fog of various concentrations depending on position.  This applies to all elements, not just krypton.

After the krytonite exposure was over he would heal and fight off the zombie virus.  Until then, the world would be in for a world of hurt.  Of course, if this is magic it might not wear off.  Supes is vurnable to magic.

Because of the ozone layers ability to vaporize the debris and meteors that come into contact w/ Earth.  Also, Superman directs the larger ones back out to space.

Nope, not as far as modern science is concerned. It's impossible. People can be a lot stronger than others, however (bodybuilders), but that's mostly steroids. As for real actual superhero abilities, they're basically just a myth...and something fun to make movies and write stories about!

I would have superman's ability to process energy from the sun, because:\na. I never HAVE to eat (except when i want to)\nb. I never have to go tinkle or number 2.\nSo, I'd save a ton of time and money by not eating or going to the bathroom, plus I'd be able to wait in lines like a champ, always getting the best seats/tickets, cause nobody could faze my line-waitin skillz at that point. Tight.

Batman actually.  Superman once gave Batman a kryptonite bullet/several bullets as well as a (modified, I think) gun so that if he ever went psycho or evil at least one person would be able to stop him.\n\nAnd Superman did that because he knew that Batman was the one person on Earth who would fire the shot.

Fruit and vegetables contain vitamins, minerals and trace minerals as well as phytohormones and fibers. All these ingedigents are important in human diet but are included less and less in modern diets. They are supposed to have been mainstays of human diet in the past but not any more. \nThis is the reason why the recommendations name them - to remind us to eat them

No.  The Batman was an ordinary human; Superman had extraordinary super-human powers.  No contest.

Lightsabres are made with crystals. If you could make one with kryptonite, I'd say it would hurt him. If not, I'd say Superman is the man of steel, period.

interaction of man with the environment is definitely essential for his survival.but the important thing is  not to exploit it.man should somewhere become satisfied and draw the line.man's insatiable quest for everything is leading to the exploitation of the environment and ultimately environmental pollution.

To cover his thingy from laser attack. He known as the last prince of his planet. He must protect his race from extinction. It's not funny if he loses his thingy. No more Kryptonian in this world. He..he...

The short answer to this question is that pathologically Lex Luthor desires to be the most powerful man in the world.  He can not accomplish this feat while Superman lives, thus he needs to kill the competition.  Much like many serial killers, politicians, or corporate big wigs (a fine line), their need for power can not be satiated and always left hungry for more.  Besides, I really don't feel like watching a movie about Superman rescuing cats from trees, even though that may have been a better 2 hours spent then Superman IV to begin with.
