Gravity is the force that causes two particles to pull towards each other. Learn about gravity and find out how Newton and Einstein explain gravity.
Nucleic acids are the molecules that contain and help express a cell's genetic code. There are two major classes of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the molecule that contains all of the information required to build and maintain the cell; RNA ha...
Here’s what to know about the irreversible eye disease at the center of the new National Geographic documentary Blink.
The idea is simple: the smaller a file is, the more you can fit in a computer, and the faster it can be transferred (传输) over the Internet. I just saved a photo of my cat, Hashtag, in two different formats. The uncompressed image (saved as BMP file) was 36.6 megabytes, while ...
A History. What was it like when human beings transformed the Earth? What was it like when humans first arose on planet Earth? What was it like when mammals appeared and thrived? What was it like when life on Earth became complex? What was it like when Venus and Mars both ...
a time. Energy only exists as a static quantity when stored in some indirect primary form, in a battery, fuel tank, rubber band, hydroelectric dam, chemical molecule or nucleus, etc, and is only able to do work when released to create an energy flux thatmustdo work, which may be to ...
DNA HP (hyper polymerised deoxyribonucleic acid), the marine-based ingredient that reduces fine lines and wrinkles, hydrates, protects, and regenerates skin.
Permanent dipolesarise due to the difference in the electronegativity (relative attraction towards electrons) between two atoms inside a molecule. Let’s consider hydrogen fluoride as an example. The electronegativity of fluorine is greater than hydrogen, and as a result, fluorine pulls all the electr...
Is an atom smaller than a molecule? What is the mass, in grams, of 4.83 x 10^32 atoms of Be? What is counted in an atom to determine mass number? What is the main chemical element of sand? What is the Rutherford model of the atom?
What properties of a molecule would cause it to deviate more or less from the ideal gas law?Ideal Gases:The ideal gas law describes the behavior of hypothetical ideal gases under a range of conditions and was developed by combining Boyle's law, Charles's law, Av...
