How air passes through the respiratory system step by step? Air enters the respiratory system through the nose and mouth and passes down the throat (pharynx) and through the voice box, or larynx. The entrance to the larynx is covered by a small flap of tissue (epiglottis) that automatically closes during swallowing, thus preventing food […]

What are the physical properties used to identify rock forming minerals?
What are the physical properties used to identify rock forming minerals? Key Concepts Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level. Color and density are determined primarily by […]
What does the right ventricle do?
What does the right ventricle do? The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest […]
What is the normal boiling point of water at sea level?
What are the factors that affect the strength of magnetic field?
What are the factors that affect the strength of magnetic field? Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core. Can magnets damage your body? […]
Where is the thinnest sediment cover in the oceans?
Where is the thinnest sediment cover in the oceans? The thinnest layers of marine sediments are generally found in deep-ocean basins near mid-ocean ridges. However, as the ocean crusts ages and moves away from the spreading centers, time allows sediments to gradually accumulate on the seafloor. Where is sediment on the seafloor the thinnest? Sediments […]
Which device opposes current?
Which device opposes current? resistor Where is the Ohms setting on a multimeter? Multimeters have three input ports for the two leads that come with it. In order to measure resistance, one of the leads — usually the black one — must be inserted in the “common” port while the other lead — the red […]
What does law of conservation of energy verified?
What does law of conservation of energy verified? The law of conservation of energy states that energy can neither be created nor be destroyed. Although, it may be transformed from one form to another. If you take all forms of energy into account, the total energy of an isolated system always remains constant. What are […]
What are 3 examples of animal adaptations?
What are 3 examples of animal adaptations? Many animals have developed specific parts of the body adapted to survival in a certain environment. Among them are webbed feet, sharp claws, whiskers, sharp teeth, large beaks, wings, and hooves. Which animal can live in water? Animals that live in water, usually called aquatic animals, include fish, […]
