Photosynthesis is the process used by plants, algae and some bacteria to turn inorganic molecules and light energy from the sun into usable chemical energy to fuel cellular function. For photosynthesis to occur, the organism requires sufficient carbon dioxide, water…
Ohm’s law is an important mathematical formula that electricians and physicists use to determine certain measurements in a given circuit. The formula is: (V=Itimes R) where V is the voltage, measured in volts, I is the amount of current measured…
The marine/saltwater biome dominates the surface of the Earth with oceans, coral reefs and estuaries covering about three-quarters of the Earth’s surface area. The world’s oceans contain the richest diversity of species of any space on Earth, while marine algae…
Like fish, reptiles and birds, almost all female insects are oviparous, meaning they lay eggs. While some egg-laying animals have nurturing instincts, tending carefully to their eggs and making sure that they are warm and protected, most insects do not…
The oceans are among the largest sources of life on Earth and is undoubtedly the largest ecosystem. Scientists traditionally divide the open ocean, or pelagic environment into five zones, each based on how much light penetrates them. The deeper the…
The structure of a seed depends on whether it comes from a monocot or dicot plant. A monocot plant has a single seed leaf, which is typically thin and long — same shape as the adult leaf. The two seed…
In mathematics, the mean, median, mode and range are common statistical measurements of a simple set of data. This last measurement is the determination of the length of the interval of all numbers in the data set. This calculation can…
Turtles are recognizable animals which have a shell, four well-developed limbs and no teeth. A turtle’s top shell is called a carapace, while the bottom one is a plastron. Turtles are adapted in a number of specialized ways because of…
At some point in their academic careers, many students must create a diorama, model or other hands-on project as a follow-up to a lesson. Often teachers use these projects as a way to cement the information in students’ minds and…
Often proceeding at small, subtle and slow rates, weathering fragments or dissolves rock: a hugely influential geological process that commonly sets the stage for erosion and provides the critical “parent material” for developing soils. The type of rock certainly influences…
