Sound waves are a form of mechanical vibration that is transferred from some object to the ear. These vibrations can be audible or inaudible and may occur as a result of a person’s voice, a musical instrument, thunder, or an earthquake. A sound wave can be heard by placing a set of headphones onto the … Read more
The decision, which can only be made public as of today, meant that the teenager is granted her request when her parents disagreed about whether the remains of her should be transferred to a specialist hospital located in the United States and cryogenically preserved. The girl’s petition may be the sole one of its kind to be considered … Read more
One of the great mysteries of the world in which we live in the light. We still do not know exactly what it is. It can only be described in terms of what it does. We know the light is a form of energy. Like some other forms of energy—heat, radio waves, and X-rays—the speed, … Read more
Arithmetic may be called the science of numbers. The word itself comes from the Greek “arithmos” which means numbers. At first, men may have counted their sheep and oxen on the fingers of their hands. The word “digit”, which means any single figure from 0 to 9 inclusive, reminds us of this, for “finger” in … Read more
A molecule is the smallest particle of a substance that can exist and still keep the properties of the whole. For example, if you broke down an of sugar, the elements would not have the characteristics of sugar—its taste or its color, among other things. Sometimes molecules are very simple, others have thousands of atoms arranged … Read more
Helicopters and airplanes are both types of aircraft that fly through the air. They are different in several ways, though. A helicopter has one main rotor blade and a tail rotor like this one while an airplane has two or more large wings to provide lift. Airplanes also have flaps on their wings that can be … Read more
Electrolytic cells and galvanic cells are both used in the construction of batteries. However, they differ in their function and design. Electrolytic cells use an electrolyte to separate the two electrodes while galvanic cells have a non-electrolyte that separates them. Electrodes in galvanic cells produce electricity by reacting with each other when they come into contact … Read more
The weight of a molecule is by scientists on a relative scale. The weight of the molecule depends upon the weight of the atoms that form it. And the weight of the atom, in turn, depends upon the number of protons and neutrons in the nucleus of the atom. A molecule of water is made up of two … Read more
These two terms are often confused and cause a lot of confusion in the context of biology. Here, we hope to clear up some confusion about these two molecules. DNA is a molecule that encodes genetic information. It consists of a long chain of nucleotides that can be found in chromosomes. RNA is a molecule … Read more
The two polymerases DNA and RNA polymerases have strikingly different properties. While DNA polymerase can synthesize a new DNA strand from a preexisting one, RNA polymerase can only transcribe an RNA strand into a DNA molecule. This fundamental difference underlies the different roles these enzymes play in vivo. In this article, we will explore these … Read more
