What comes first population or community? Individuals make up a population; populations make up a species; multiple species and their interactions make up a community; and multiple species and their interactions make up ecosystems when you include the abiotic factors. This is the hierarchy of ecology. What defines the number of organisms living in a […]

What does your circulatory system do for your digestive system?
What does your circulatory system do for your digestive system? The circulatory system is a good example of how body systems interact with each other. Your heart pumps blood through a complex network of blood vessels. When your blood circulates through your digestive system, for example, it picks up nutrients your body absorbed from your […]
What is the difference between light and heavy pressure plates?
What is the difference between light and heavy pressure plates? Weighted Pressure Plates emit a redstone signal when items are dropped on to it. The strength of the redstone signal is based on how many items are on top of it. Weighted Pressure Plate (Light)s require less items on it to emit the strongest redstone […]

What is the purpose of inductor in a circuit? An inductor is a passive electronic component which is capable of storing electrical energy in the form of magnetic energy. Basically, it uses a conductor that is wound into a coil, and when electricity flows into the coil from the left to the right, this will […]
Is there a planet partially made of diamonds?
Is there a planet partially made of diamonds? In October 2012, it was announced that 55 Cancri e showed evidence for being a carbon planet. It has eight times the mass of Earth, and twice the radius. Research indicates that the 2,150 °C (3,900 °F) planet is “covered in graphite and diamond rather than water […]

Why do ships float Archimedes Principle?
Why do ships float Archimedes Principle? Why the Ship Floats Archimedes’ buoyancy principle states that buoyant force — what keeps the ship afloat — is equal to the weight of water that is displaced when the ship enters the ocean. If the weight of displaced water is at least equal to the weight of the […]
What is the most important function of stratospheric ozone?
What is the most important function of stratospheric ozone? Stratospheric ozone is a naturally-occurring gas that filters the sun’s ultraviolet (UV) radiation. This is typically regarded as ‘good’ ozone since it reduces the harmful effects of ultraviolet (UV-B) radiation. A diminished ozone layer allows more radiation to reach the Earth’s surface. Why is o3 unstable? […]
