How is metabolism important in nutrition processes? Nutrition is the key to metabolism. The pathways of metabolism rely upon nutrients that they breakdown in order to produce energy. This energy in turn is required by the body to synthesize molecules like new proteins and nucleic acids (DNA, RNA). How is metabolism regulated in the body? […]
Why is organic farming better?
Why is organic farming better? Organic farming tends to be better for the environment. Organic farming practices may reduce pollution, conserve water, reduce soil erosion, increase soil fertility, and use less energy. Farming without synthetic pesticides is also better for nearby birds and animals as well as people who live close to farms. Are organic […]
What type of current is used in arc welding?
What type of current is used in arc welding? Both direct current (D.C.) and alternating current (A.C.) are used for arc welding. The alternating current for arc is obtained from a step down transformer. The transformer receives current from the main supply at 220 to 440 volts and step down to required voltage i.e., 80 […]
Which of the following is suitable for job shop production?
Which of the following is suitable for job shop production? General purpose machines are suitable in job shops because they are capable of performing many different types of operations and thus capable of producing a wide variety of products with small lot sizes. Machines which perform similar function grouped together. What is meant by job […]
What are the different mechanisms for diffusion?
What are the different mechanisms for diffusion? Diffusion can occur by two different mechanisms: interstitial diffusion and substitutional diffusion. Picture an impurity atom in an otherwise perfect structure. Which diffusion mechanism is faster interstitial or vacancy? Interstitial diffusion is generally faster than vacancy diffusion because bonding of interstitials to the surrounding atoms is normally weaker […]
How do you find the maximum theoretical efficiency?
How do you find the maximum theoretical efficiency? The maximum theoretical efficiency of a heat engine (which no engine ever attains) is equal to the temperature difference between the hot and cold ends divided by the temperature at the hot end, each expressed in absolute temperature (Kelvin). What is the theoretical maximum efficiency? The Carnot […]
What does the amount of energy to change temperature of an object depend on?
What does the amount of energy to change temperature of an object depend on? The change in temperature of a system depends on: the amount of thermal energy transferred to the system. the mass of the substance. the nature of the substance itself. What is the relationship of the amount of heat transferred between bodies […]
How many rotations and color changes are needed to perform per insertion deletion in a red black tree?
How many rotations and color changes are needed to perform per insertion deletion in a red black tree? Solution: True, at most two rotations are performed. (b) Is it true that in the worst case a red-black tree deletion requires O(1) node recolorings? When a node is first inserted in a red black tree it […]
What are the physical properties and uses of sulfur?
What are the physical properties and uses of sulfur? Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water. It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements. What are the 3 […]
What is a secondary motion?
What is a secondary motion? Secondary animation also known as secondary motion, is used to refer to flat motions that are generated as a reaction to the movement of primary motion by a character. Examples of secondary motion include the rippling of water, swish of a cloak, or jiggle of body parts when a person […]
