What is the function of stomata class 9th? Functions of Stomata The major function of stomata is the exchange of gases by taking carbon dioxide from the atmosphere and giving out oxygen that is used by human beings and animals. They help in photosynthesis and transpiration. What do stomata say? Stomate, also called stoma, plural […]
What is the main organ of circulatory system?
What is the main organ of circulatory system? The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body. What is the main function of a circulatory system? The circulatory system delivers oxygen and nutrients to cells and takes away wastes. […]
What happens if you put a vibrating tuning fork in water?
What happens if you put a vibrating tuning fork in water? By sticking the vibrating tuning fork in a denser medium like water, the tuning fork’s energy is transferred into the act of splashing water, rather than hearing sound. Waves are energy carriers. Water is a better medium to visualize sound waves and detect the […]
How does temperature affect equilibrium constant?
How does temperature affect equilibrium constant? Increasing the temperature decreases the value of the equilibrium constant. Where the forward reaction is endothermic, increasing the temperature increases the value of the equilibrium constant. If you increase the temperature, the position of equilibrium will move in such a way as to reduce the temperature again. What do […]
How does removing a bulb or opening and closing the switch affect a parallel circuit?
How does removing a bulb or opening and closing the switch affect a parallel circuit? An obvious advantage of parallel circuits is that the burnout or removal of one bulb does not affect the other bulbs in parallel circuits. They continue to operate because there is still a separate, independent closed path from the source […]
What is a available energy?
What is a available energy? physics. : that part of the energy of bodies or systems which exists under such conditions that work may be theoretically derived from it — compare degradation of energy, entropy, unavailable energy. What is available energy AE? The maximum work output obtainable from a certain heat input in a cyclic […]
Why does water move through a membrane quizlet?
Why does water move through a membrane quizlet? Water moves through a membrane in osmosis because there is a concentration gradient across the membrane of solute and solvent. The solute cannot effectively move to balance the concentration on both sides of the membrane, so water moves to achieve this balance. Why does water move through […]
Which planet has no gravitational force?
Which planet has no gravitational force? It takes a team of scientists doing very accurate calculations to make sure a space probe destined for the surface of Mars doesn’t miss it. Falling in circles around a planet instead of smashing into it doesn’t seem like the gravity we’re used to on earth, but it’s the […]
What is a major turning point?
What is a major turning point? The major turning-points are clearly defined and structurally fixed: inciting incident, plot point 1, pinch point 1, midpoint, pinch point 2, plot point 2, climax and last twist. Therefore they always cause a major change within the plot. How do you find the turning point? The easiest way to […]
Why does intensity decrease with distance?
Why does intensity decrease with distance? There is an inverse relationship between distance and light intensity – as the distance increases, light intensity decreases. This is because as the distance away from a light source increases, photons of light become spread over a wider area. How much louder is 70 dB to 50db? Yet that […]
