When it does venture out of its den, the octopus uses one of several methods to get around. The preferred method of locomotion for many octopuses is a form of walking. Rows of suckers on the underside of each arm enable the octopus to move itself forward along the sea floor. Because its...
To determine how many statements regarding the Earth Summit are correct, let's analyze each statement one by one:1. Statement (i): Held at Johannesburg, South Africa - This statement is incorrect. The Earth
protons, and electrons emitted by the Sun (Geiss et al.1995; Galvin et al.1996). If it was not for the GMF, the energy carried by wind particles would be transferred directly to the particles of the atmosphere, giving them additional...
The transition from fossil fuels to a renewable energy supply is one of the most important global challenges of the 21st century. In order to achieve the internationally-agreed target of limiting ...
For example, shining ultraviolet light onhydrogen cyanide(a chemical compound that exists in nature) in water, along with an negatively charged ion (an atom that has gained electrons) such as bisulfite,leads to simple sugars. Hydrogen cyanide is abundant in the "protoplanetary disks" which form ...

Using a particle accelerator, the scientists managed to replace one of a helium atom's orbiting electrons with a muon, a subatomic particle similar to an electron, but with a mass around 200 times greater. Because it's so massive, the muon crowds the nucleus and cancels out one of the ...
The illumination of nanostructures made from metals with a negative real and small positive imaginary dielectric constant (for example, silver or gold nanostructures) leads to an excitation of the collective oscillations of surface conduction electrons known as surface plasmons. Surface plasmons may be ...
DNA damage is induced by many factors, some of which naturally occur in the environment. Because of their sessile nature, plants are especially exposed to unfavorable conditions causing DNA damage. In response to this damage, the DDR (DNA damage response) pathway is activated. This pathway is ...
