What is the main source of energy for the plant? the Sun Do the sun is only source of energy for photosynthesis? The Sun is an infinite (at least in terms of human time scales) and renewable source of energy which is also by far the most important source of energy for us. Primary productivity […]

What is the condition of a starved evaporator coil? A starved evaporator coil is a condition in which not enough refrigerant has been supplied through the total coil length. Therefore, expansion of the refrigerant has not occurred through the whole coil length, resulting in poor coil operation and too-low heat exchange. When a refrigeration unit […]

Can animals see UV? What they found suggests that most mammals can, in fact, see UV light—including dogs, cats, ferrets, and reindeer. Unlike humans, these mammals have lenses that allow UV light though. Even though they lack the specialized UV-sensitive type of cone, the other three kinds of cones can combine to make up for […]

Why places near the sea have humid climate? Coastal cities that are closer to the sea and oceans are humid as a result of their proximity to the water bodies. Air always holds some degree of water vapour in it. So there is a specific amount of vapour that air can hold. Is humidity higher […]

How do I calculate the average percentage increase? To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Increase = New Number – Original Number. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × […]

Is Mg OH 2 an acid or base? Because Mg(OH)2 is listed in Table 15.6. 1, it is a strong base. The nitrogen in C5H5N would act as a proton acceptor and therefore can be considered a base, but because it does not contain an OH compound, it cannot be considered a strong base; it […]

Why must an accurate percent yield be below 100%? Percent yield is the percent ratio of actual yield to the theoretical yield. Usually, percent yield is lower than 100% because the actual yield is often less than the theoretical value. Reasons for this can include incomplete or competing reactions and loss of sample during recovery. […]

Does high ionization energy mean high electronegativity? Ionization Energy Elements with high ionization energies have high electronegativities due to the strong pull exerted on electrons by the nucleus. Does P or CL have a higher ionization energy? The second ionization energy is always larger than the first ionization energy, because it requires even more energy […]

Why does the jet stream move from west to east? The jet stream is a narrow band of fast, flowing air currents located near the altitude of the tropopause that flow from west to east. The jet stream flows around the entire earth. They usually have a meandering, snake-like shape. These winds shift west to […]

What are the basic principles of visual design? The elements, or principles, of visual design include Contrast, Balance, Emphasis, Movement, White Space, Proportion, Hierarchy, Repetition, Rhythm, Pattern, Unity, and Variety. These principles of design work together to create something that is aesthetically pleasing and optimizes the user experience. What is the importance of elements of […]
