What are the characteristics of plants that can survive in the tundra? The features which make it able to survive are: low-lying – the snow covers it in winter which helps insulate it. seeds that scatter in the wind. narrow leaves helping to reduce transpiration. adapted to a short growing season (so has a short […]
What are reactants examples?
What are reactants examples? Reactants are substances initially present in a chemical reaction that are consumed during the reaction to make products. Some chemical reactions go to completion, resulting in all of the reactants becoming products. These reactions are said to be irreversible. For example, burning methane in oxygen is irreversible. What are the 7 […]
Which bird can fly without flapping wings?
Which bird can fly without flapping wings? albatross Do birds sleep while flying? Due to the lack of studies monitoring the sleep patterns of flying birds, these hypotheses had previously been left unconfirmed. Now, however, according to a new study from the Max Planck Institute for Ornithology, researchers have finally found evidence that birds do […]
Do Coral reefs produce oxygen?
Do Coral reefs produce oxygen? While coral reefs only cover 0.0025 percent of the oceanic floor, they generate half of Earth’s oxygen and absorb nearly one-third of the carbon dioxide generated from burning fossil fuels. How do coral reefs benefit from herbivorous fish? Another functional group of herbivorous fishes are the ‘grazers’. Much like a […]
Why doesnt horizontal motion affect vertical motion?
Why doesnt horizontal motion affect vertical motion? The horizontal velocity remains constant, because there is no acceleration in that direction. The length of the horizontal velocity vector doesn’t change. THE VERTICAL & HORIZONTAL MOTIONS ARE INDEPENDENT. THE HORIZONTAL VELOCITY DOES NOT AFFECT THE VERTICAL MOTION. Does velocity change with angle? When an object is projected […]
Does yellow light have a higher frequency than blue?
Does yellow light have a higher frequency than blue? So red light vibrates at about 400 million million cycles per second. Fast! Higher frequency (with shorter wavelength) has more energy: Red light has lower frequency, longer wavelength and less energy….Visible Spectrum. Color Wavelength Range (nm) Yellow 570–590 Green 495–570 Blue 450–495 Violet 380–450 Does yellow […]
Is flammability a physical or chemical property?
Is flammability a physical or chemical property? Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Is odor a physical or chemical property? Properties that can be determined without changing the […]
What results when two atoms share electrons?
What results when two atoms share electrons? A covalent bond results when two atoms share electrons. In the case of two hydrogen atoms, each shares its single electron with the other. This sharing allows each to fill its electron shell with two electrons. The pair of shared electrons constitutes a covalent single bond. How many […]
Does light travel forever?
Does light travel forever? As long as it doesn’t get absorbed by something, then yes, light will continue to travel indefinitely. However, due to the expansion of the universe that light wave will get stretched out along with the space it travels through, becoming lower in frequency and energy. Is darkness a form of light? […]
