However may the substances the Act applies to, in principle be used to produce such weapons.

The biochemist Bruce Ames and his colleagues have found that 99.99 (by weight) of the pesticides in the American diet are chemicals that plants produce to defend themselves. Only 52 natural pesticides have been tested in high dose animal cancer tests, and about half (27) are rodent carcinogens these 27 are shown to be present in many common foods.

Those blooms are generating other kinds of chemicals.

We are huge packages of chemicals.

Living organisms are created by chemistry.

Chemistry, my fellow, is the material manifestation of the metaphysical.

Food additive means any synthetic compound or natural substance put into food to improve its quality, colour, fragrance or taste, or for the sake of preservation or processing.

That terminology has stuck, but it doesn't actually refer to specific chemicals because these chemicals come in a lot of different shapes and forms.

The highest risks are associated with the laboratory handling of dangerous organic and chemical substances.

I have linear algebra, science, physics, even nowadays, chemistry and biology, as you've seen.

In the title, insert AND MIXTURES after SUBSTANCES .

Meteorites delivered chemistry, and perhaps membranes, too.

So maybe the chemical in that would be useful.

Chemical substances and precursors were subject to strict controls.

So when we see E equals mc squared come along, from a poet's perspective, we see energy as physics, chemistry as mass, and all of a sudden, you get this biology.

Yet, it's 3,000 times tougher than its geological counterpart.

And this particular plant removes formaldehydes and other volatile chemicals.

What that means is, I can mix some chemicals together in a test tube in my lab, and these chemicals will start to self associate to form larger and larger structures.

Now, what are the ideal conditions for chemistry?

It's like electrical shock that releases the chemicals from these synapses.

Prohibiting the use of chemical substances not marked in a way allowing for their identification

It's 115 miles of mapped passage, it's pristine, it has no natural opening and it's a gigantic biological, geo microbiological laboratory.

This was a result that the first reaction when we saw the water turning green was to use one of the chemicals chlorine that is very common in swimming pools.

The members of drafting group on chrysotile asbestos established by the first meeting of the Chemical Review Committee were Mr. K Berend and Mr.

are authorized for the transport of any liquid or solid substance other than explosives, thermally unstable substances, organic peroxides, self reactive substances, substances where significant pressure may develop by evolution of chemical reaction and radioactive material (unless permitted in 4.1.9).

And we're now going to put some chemistry inside and do some chemistry in this cell.

During a chemical reaction mass is neither lost nor gained. The sum mass of the material going into the reaction equals the sum of the mass of the products of the reaction.

I want to know if there's a chemistry of morality.

284 An oxygen generator, chemical, containing oxidizing substances should meet the following conditions

It leaches out chemicals into the flesh of the poor critter that ate it, and then we come along and eat that poor critter, and we get some of the toxins accumulating in our bodies as well.

And chemokines are essentially chemical attractants, and they're the stop and go signals for cancer.

Juan Enriquez challenges our definition of bioenergy. Oil, coal, gas and other hydrocarbons are not chemical but biological products, based on plant matter and thus, growable. Our whole approach to fuel, he argues, needs to change.
