Why do electrons lose energy? An excited atom is unstable and tends to rearrange itself to return to its lowest energy state. When this happens, the electrons lose some or all of the excess energy by emitting light. Does losing an electron release energy? When electrons are removed from an atom, that process requires energy […]
How do you know if three forces are in equilibrium?
What organisms are responsible for nitrogen fixation?
What organisms are responsible for nitrogen fixation? Two kinds of nitrogen-fixing microorganisms are recognized: free-living (nonsymbiotic) bacteria, including the cyanobacteria (or blue-green algae) Anabaena and Nostoc and genera such as Azotobacter, Beijerinckia, and Clostridium; and mutualistic (symbiotic) bacteria such as Rhizobium, associated with leguminous plants. How is nitrogen produced? Commercial production of nitrogen is largely […]
Can rubber be stretched?
Can rubber be stretched? The ability to stretch is what we call elasticity (elasticity is the noun, elastic is the verb). Rubber is elastic because the chemical bonds that hold it together can store energy in the form of tension and allow the rubber to stretch, Beyond that I don’t think I’m qualified to explain. […]
What is capacitance and dielectrics?
What is capacitance and dielectrics? capacitance: amount of charge stored per unit volt. dielectric: an insulating material. dielectric strength: the maximum electric field above which an insulating material begins to break down and conduct. What is resistance and capacitance? Resistance is the measure of the amount of energy dissipated by the resistor. While capacitance is […]
Which statement is part of the Malthusian theory quizlet?
Which statement is part of the Malthusian theory quizlet? Malthus argues that population increases exponentially example if a couple have two children and each of those two children have two children the result would be four grandchildren if those four grandchildren each have two children the result to be eight Great grandchildren if a couple […]
What animal has the best regeneration?
What animal has the best regeneration? Axolotl. A relative of the salamander but even more skilled at regenerating is the axolotl. This animal can regenerate not just its tail but also limbs, skin and almost any other body part. Researchers found that each time a limb was removed, it regrew almost perfectly. Which animal can […]
Which is short range force?
Which is short range force? [′shȯrt ¦rānj ′fȯrs] (physics) A force between two particles which is negligible when the distance between the particles is greater than a certain amount; in particular, nuclear forces whose range is several times 10-15 meter. Can Mewtwo defeat arceus? In the movie Arceus and the Jewel of Life, Arceus isn’t […]
What triggers the sodium-potassium pump?
What triggers the sodium-potassium pump? The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell. […]
What are 5 animals that cause biological weathering?
What are 5 animals that cause biological weathering? Burrowing animals like shrews, moles, earthworms, and even ants contribute to biological weathering. In particular, these animals create holes on the ground by excavation and move the rock fragments to the surface. How do plants and animals help weather rocks and soil? – weathering breaks down rocks […]
