It's not different, it's the same stuff calcium carbonate, calcium carbonate.

And they can pull calcium out of the environment, put down a layer of calcium and then carbonate, calcium and carbonate.

And they said, calcium carbonate.

Medullary tissue is the calcium build up, the calcium storage basically, when an animal is pregnant, when a bird is pregnant.

Other minerals include calcium, uranium, lignite and copper.

It's possible because the mycelium produces oxalic acids, and many other acids and enzymes, pockmarking rock and grabbing calcium and other minerals and forming calcium oxalates.

The main framework material of coral reefs is calcium carbonate.

And I said, that's what this is this is calcium carbonate.

When you evaporate seawater, the first thing to crystallize out is calcium carbonate.

You can see the calcium buildup on the head of the poporo gourd.

So, fungi and mycelium sequester carbon dioxide in the form of calcium oxalates.

Oh, by the way, just in case you weren't already guessing, it's calcium carbonate.

There are many organisms that build their shells out of calcium carbonate plants and animals both.

So vitamin D is good for you it stops rickets, it prevents calcium metabolism, important stuff.

This abalone shell is a biocomposite material that's 98 percent by mass calcium carbonate and two percent by mass protein.

And that builds up on the evaporators and that's what that image on the left is gradually getting encrusted with the calcium carbonate.

And why? Because the lowly abalone is able to lay down the calcium carbonate crystals in layers, making this beautiful, iridescent mother of pearl.

And it was during this time that there was increased calcium and iron and silicon in the environment, and organisms learned how to make hard materials.

So which means that it's really impossible to find an object where you find about 10 times more sulfur than silicon, five times more calcium than oxygen. It's just impossible.

But if you break a gourd, you cannot simply throw it away, because every stroke of that stick that has built up that calcium, the measure of a man's life, has a thought behind it.

We can see the calcium from the world's deserts, soot from distant wildfires, methane as an indicator of the strength of a Pacific monsoon, all wafted on winds from warmer latitudes to this remote and very cold place.

ASCA gives astronomers a better tool for direct observation of the emissions from many atoms, including oxygen, silicon, calcium, and iron, in the ejected gas of supernovae, lasting for many hundreds of years after the explosion that created the supernova.

Ideal and belief serve as calcium for the spirit of members of the Communist Party, so we must strength ideological and political construction and solve any problem concerning outlook on world, outlook on life and values, which is the master switch .

Using new data from the Advanced Satellite for Cosmology and Astrophysics (ASCA, launched by Japan in February 1993) about two supernova remnants (designated E0519 69.0 and N103B) in the Large Megallanic Cloud, a binational team of astronomers led by SAO apos s John P. Hughes discovered significant amounts of iron, calcium, and other newly synthesized elements.
