Japanese scientists detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu ...

“Urea hydrolysis will drive soil pH around the nitrogen molecule to near 9,” Ferrie says. “This can happen within two to four days of application. In moist, warm, high-pH ...

The dot and cross diagram shows that a water molecule is made up of one oxygen atom joined to two hydrogen atoms, so the formula of water is H 2 O. A nitrogen molecule is made up of two nitrogen ...

When the Sun is near the horizon, its light passes through a lot more of the atmosphere to reach the Earth's surface than ...

The nitrogen molecule is composed of two nitrogen atoms joined by a triple covalent bond, thus making the molecule highly inert and nonreactive. Nitrogenase catalyzes the breaking of this bond and ...

Atoms and molecules make up all of the different substances ... They are given white, red, blue, and black cubes that represent hydrogen, oxygen, nitrogen, and carbon atoms respectively. Students are ...

"By selectively adding one nitrogen atom to these existing drug heterocycles in the later stages of development, we can change the molecule's biological and pharmacological properties without ...
