Collection of food sample and write thier uses along with thier nutrient |
|
Answer» The quality of sampling and analytical data is a major determinant of DATABASE quality. Sampling foods for inclusion in a compositional database is one of the more demanding and difficult ASPECTS of database preparation and OFTEN requires the compilers to make intuitive judgements and compromises. This chapter reviews the objectives of sampling and discusses the various aspects for consideration in making these judgements.Where the necessary information on the composition of a food is not available (as is often the case in developing countries) or is inadequate (e.g. it is no longer applicable to the current food supply or the analytical values need to be measured using more recent methods), then sampling and analytical protocols need to be devised.Ideally these should be DEVELOPED in conjunction with each other because the requirements of the ANALYSTS will determine the amounts of foods necessary for the analyses and how the foods should be stored and, if necessary, preservedExplanation:Mark me as the brainliest.. |

|
Answer» a. Carbon compounds are used as fuel because they burn with a clean flame and no smoke is produced. ... Carbon and their compounds GIVE out a lot of heat, energy and light when they are burnt in air and this is mainly because carbon compounds have greater calorific values.b. Carbon also exists in its many allotropic forms such as graphite, diamond, buckminsterfullerene, etc. HOWEVER, carbon mostly occurs as a tetravalent compound in nature in the form of hydrocarbons. Additional Information: The most ABUNDANT element (by mass) found in nature is hydrogen, followed by helium and oxygen.c. (1)Diamond is used in rock drilling and glass cutting machine. (2) Diamond knives are used in eye surgery. (3) Diamond is used in ornaments. (4) Diamond DUST is used to cut other diamonds.

Stars twinkle at night give reasonno spamfoll.ow me |
|
Answer» In the atmosphere, there are DIFFERENT layers of air with different refractive INDICES which KEEP on changing.When we observe the stars through this air the light coming from them refract randomly so that the intensity of light varies due to which the apparent position of the star fluctuates.When more light reaches our eyes the star is seen bright and when less light reaches our eyes, the star is seen dim.Thus, due to change in refractive index of atmosphere, stars appear twinkling at night.

What is nature of image formed by plane mirror & where is it formed ? |
|
Answer» A PLANE MIRROR is made using some highly reflecting and polished surface such as a silver or aluminium surface in a process called silvering. After silvering, a thin layer of red lead oxide is APPLIED at the back of the mirror. The reflecting surface reflects most of the light striking it as long as the surface remains uncontaminated by tarnishing or oxidation. Most modern plane mirrors are designed with a thin piece of plate glass that protects and strengthens the mirror surface and helps prevent tarnishing. HISTORICALLY, mirrors were simply FLAT pieces of polished copper, obsidian, brass, or a precious metal. Mirrors made from liquid also exist, as the elements gallium and mercury are both highly reflective in their liquid state. |

What are worm gears and what are rack and pinion gear?who tells write gets thank you |
|
Answer» RACK AND PINION: The rack and pinion is used to convert between rotary and linear motion. The rack is the flat, toothed part, the pinion is the GEAR. Rack and pinion can convert from rotary to linear of from linear to rotary. The diameter of the gear determines the SPEED that the rack moves as the pinion turns. Rack and pinions are commonly used in the steering SYSTEM of cars to convert the rotary motion of the steering WHEEL to the side to side motion in the wheels. Rack and pinion gears give a positive motion especially compared to the friction drive of a wheel in tarmac. In the rack and pinion railway a central rack between the two rails engages with a pinion on the engine allowing the train to be pulled up very steep slopes.WORM GEAR: A worm is used to reduce speed. For each COMPLETE turn of the worm shaft the gear shaft advances only one tooth of the gear. In this case, with a twelve tooth gear, the speed is reduced by a factor of twelve. Also, the axis of rotation is turned by 90 degrees. Unlike ordinary gears, the motion is not reversible, a worm can drive a gear to reduce speed but a gear cannot drive a worm to increase it. As the speed is reduced the power to the drive increases correspondingly. Worm gears are a compact, efficient means of substantially decreasing speed and increasing power. Ideal for use with small electric motors.Hope it helps you..Please mark me as Brainliest. |

These seeds tend to develop a fibrous or spongy coating. Example – coconutWind – some light-weighted seeds tend to float in air and hence are dispersed by wind. Example – MapleAnimal – Seeds that are dispersed by animals have spines which helps them attach to the animal bodies, hence carried to DISTANT places.
