What three organelles are unique to plant cells? Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules. Which two organelles help support the plant […]

What happens when the amplitude of a light wave increases?
What happens when the amplitude of a light wave increases? In the picture above, wavelength is the distance from crest to crest (or trough to trough as well) along the length of the wave. The amplitude is the distance up and down from crest to trough. In classical wave physics the energy of a wave […]
What how does suspension appear?
What how does suspension appear? An suspension is when you mix a liquid and a solid, where the solid does not dissolve in the liquid. If this appears then you have an suspension. The suspension will appear as small “grain” looking object floating in the solution. What do you mean by suspension? A suspension is […]
Is heat of fusion positive or negative?
Is heat of fusion positive or negative? So the heat of fusion is an endothermic process it requires heat so the delta h is positive. Heat solidification is exothermic going from liquid to solid, releases heat so it’s a negative delta h but at they’re the same numbers. Why is heat of fusion important to […]
What happens if you add a resistor in parallel?
What happens if you add a resistor in parallel? When resistors are connected in parallel, more current flows from the source than would flow for any of them individually, so the total resistance is lower. Each resistor in parallel has the same full voltage of the source applied to it, but divide the total current […]

Is H2 O2 H2O a balanced equation?
Is H2 O2 H2O a balanced equation? The obtained result indicates that the oxygen atom is not equal on both sides. Thus the reaction is not balanced. The balanced reaction has the number of atoms involved in reaction in reactants as well as the product is equal. What came first sun or Earth? Newsletter. The […]
