What are the main aims of classification? The goal of classifying is to place an organism into an already existing group or to create a new group for it, based on its resemblances to and differences from known forms. To this end, a hierarchy of categories is recognized. What are the aims and objectives of […]

What is cubical expansion of liquids? 2. Define apparent cubical expansion of a liquid. Answer. Observed increase in volume of a liquid (excluding expansion of the vessel), is called apparent cubical expansion of the liquid. What are two examples of thermal expansion in liquids? Liquids ENGINE COOLANT. Another example of thermal expansion on the part […]

What happens to the electron transport chain of oxygen is lacking? What happens to the electron transport chain when oxygen is not available? Explanation: Oxygen is the final electron acceptor in the electron transport chain, which allows for oxidative phosphorylation. Without oxygen, the electrons will be backed up, eventually causing the electron transport chain to […]

What is organic farming What are its limitations? Limitation: Organic manure is not abundantly available and on plant nutrient basis it may be more expensive than chemical fertilizers if organic inputs are purchased. Production in organic farming declines especially during first few years, so the farmer should be given premium prices for organic produce. What […]

Which of the following pairs of physical quantities are not analogous? Couple and Torque are actually in the same context because both are produced due to the application of force. Moreover both are the faces of same coin. Hence they are not analogous to each other. What is moment of inertia analogous to? In calculating […]

What are the 3 main groups of global winds? There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig. What are the factors that contribute to global winds? Global winds are affected by convection current, pressure gradients, the Coriolis effect, and friction. What are […]

How do you round a significant figure to 3? We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits. We then round the last digit. We fill in any remaining places to the right of […]

Why is sky blue not violet? The smaller the wavelength of the light the more the light is scattered by the particles in the atmosphere. This is because the sun emits a higher concentration of blue light waves in comparison violet. Furthermore, as our eyes are more sensitive to blue rather than violet this means […]
