Pounds per square inch (psi) is a unit of pressure most commonly associated with tire pressure for an automobile or bike tire. However, because pressure gauges are attached to most tire pumps, there’s often very little need to calculate psi…
Acidic solutions are any solution that has a higher concentration of hydrogen ions than water; solutions that have a lower concentration of hydrogen ions than water are called basic or alkaline solutions. Classification Acidity is measured on a scale known…
Unshared electrons refer to outer (valence) electrons not part of a covalent bond. Shared electrons are those participating in a bond. Subtract the number of shared electrons (bonds x 2) from the number of valence electrons to discover number of…
Electrons are one of the three basic constituents of atoms, the other two being protons and neutrons. Electrons are extremely small even by the standards of subatomic particles, with each having a mass of 9 × 10-31 kg. Because electrons…
Some plants, such as potatoes and other tubers, and fruits like the banana and breadfruit, store starch for later use. This starch is stored by special organelles, or cell subunits, called amyloplasts. Storage Process Plant starch begins as glucose, a…
The temperate deciduous forest is one of the Earth’s most diverse and populated biomes. Deciduous forests stretch up the east coasts of China, the United States and Australia, fill the islands of New Zealand and Japan, and cover most of…
In science, an educated guess about the cause of a natural phenomenon is called a hypothesis. It’s essential that hypotheses be testable and falsifiable, meaning they can be tested and different results will ensue depending on whether the hypothesis is…
Sponges may look like plant life, but they are actually animals. These sea-bottom dwellers are very simple multi-cellular creatures. There are various types of sea sponges found on reefs and deep-sea bottoms. Some are loners, while others grow in colonies.…
Red fox urine acts as a repellant for many small mammals, including squirrels, rats, skunks and chipmunks. Fox urine works particularly well as a repellant due to its strong smell and volatile chemical structure. As a result, many people use…
Owls are one of the most identifiable nocturnal animals, meaning they are known for being alert at night and sleeping during the day. While not all owls are nocturnal, many are and the owl noises they make are often heard…
