The five major lines of latitude, more commonly referred to as the five major circles of latitude, mark specific points on a globe or map of Earth. Four of the lines run parallel to the equator and sit north or…
Over the centuries, scientists have discovered laws that explain how properties such as volume and pressure affect the way gases behave. You witness real life applications of at least one of these laws – Boyle’s law – daily, perhaps without…
Multiple ecosystems and hundreds of plant and animal species exist in the tundra biome. It encompasses both arctic and alpine tundra. The arctic tundra resembles a snowy desert surrounding the North Pole, while the alpine tundra is located in the…
Technical writers often use decimals to express weights, such 4.25 pounds. That same weight, however, can also be expressed in the common units of pounds and ounces: 4.25 pounds is the same as 4 pounds, 4 ounces. Knowing that there…
Phytoplankton are microscopic creatures that multiply prolifically through asexual and sexual means. Reproductive rates of phytoplankton directly affect and reflect the balance of the ecosystem. According to National Geographic, marine plants like phytoplankton, algae and kelp produce 70 percent of…
Sucralose (C12H19O8Cl3) is a no-calorie, artificial sweetener derived from sucrose. It is a chlorine-substituted disaccharide composed of one glucose and one fructose unit. Resistant to hydrolysis in the digestive tract, sucralose produces no glycemic response and is thus safe for…
Carpenter bees, also known as wood bees, come in two varieties: the genus Xylocopa, or large carpenter bees, and the genus Ceratina, or small carpenter bees. A typical large carpenter bee is about the size of a bumblebee – about…
The gas laws are easy to demonstrate with everyday household items. These related scientific principles describe how the volume, pressure and temperature of a gas change under various conditions, and represent a cornerstone of chemistry and physics. A gas law…
By definition, a circle is the most circular object. It is also the most compact in the sense that it encloses the most area for a given perimeter. There are many applications in which you want to say just how…
In biological experiments, standardized variables are those that remain the same throughout the experiment. But there are several different variables that help a scientist discover new information. The independent variable is the aspect of the experiment that is changed or…
