What do most plants need to grow? Plants, like all living organisms, have basic needs: a source of nutrition (food), water, space in which to live, air, and optimal temperatures in order to grow and reproduce. For most plants, these needs are summarized as light, air, water, and nutrients (known by the acronym LAWN). How […]
What comes first population or community?
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 forms of energy changes take place when a gun is fired?
What forms of energy changes take place when a gun is fired? A bullet stores chemical potential energy in its gunpowder. When the bullet is fired, this chemical energy is converted into kinetic energy and heat. Why does the Dart have a little bit of gravitational potential energy before it is fired? However, the dart […]
Is gravity created by mass?
Is gravity created by mass? So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That’s what gives you weight. Does rotation affect gravity? While the spinning of the […]
Did they find a Megalodon in the Mariana Trench?
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 purpose of inductor in a circuit?
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 […]
Why do pots boil over?
Why do pots boil over? With the combined influences of heat and water, the starch thickens as it rises to the surface, creating an active agent at the top of the water which blocks air from escaping. Because it contains more air, the volume of water then expands, rising to the point of boiling over. […]
