Why do we ill |
| Answer» There are two types of factors that causes diseases – extrinsic factors and intrinsic factors. \tThe disease causing factors which exist within the human body are called intrinsic factors. Example – malfunctioning of various body parts, hormonal imbalances, genetic disorder, etc.\tThe disease causing external agents which enter the human body from outside are referred to as extrinsic factors. Example – unbalanced diet, environmental pollutants, etc. | |

Different between earth atmosphere and venus |
| Answer» Venus is often named as Earth\'s twin because both worlds share a similar size, surface composition and have an atmosphere with a complex weather system.The figure on the right compares Venus and Earth spacecraft images. The surface of Venus is shown in orange as radar images while the atmosphere is reproduced on near true colors as it would be seen by the human eye. The upper clouds are brightest in the blue and ultraviolet wavelengths making Venus a white-blue colour planet. Both planets have almost the same size and density and Venus is only a 30% closer to the Sun than Earth. Both share an interesting geological evolution with old volcanoes in Venus and some of them could still be active. One of the biggest misteries of Venus is why its surface is so young on geological time-scales. It is interesting to remark that there is almost no water on Venus\' atmosphere.There are many more differences between both planets.Whereas Earth rotates in about 24 hours Venus rotates in the contrary sense (retrograde rotation) in 243 days. The orbital period of Venus is 225 days so that a Venus year takes less than a full day. The combination of these two periods results in the Sun appearing from the West and dissapearing over the East with a day-night cycle of 117 days.The atmosphere of Venus is 90 times more dense than that on Earth and it is made of 96.5% of CO2 and a 3% of nitrogen. This means that both planets have the same amount of Nitrogen on their atmospheres. Surprinsingly the CO2 on Earth is stored on calcite type rocks and if we would convert the CO2 on these rocks into atmospheric CO2 it would amount to the same amount of CO2 that there is on Venus\' atmosphere.Because of the denser atmosphere and the chemical composition Venus experiences an inmense green-house effect that raises the temperature over the surface to more than 470ºC.Green-house effect on VenusThe figure on the right illustrates the basics of the greenhouse effect on Venus. Long-wave radiation from the Sun is mainly reflected at the upper cloud deck and partially absorbed by the atmosphere but part of it reaches the surface and heats the lowest atmosphere. The hot surface cools down emitting short-wave radiation that is absorbed and re-emitted by the green-house gases of the atmosphere impeding cooling of the planet and originating the high temperatures at the surface. Figure extracted from here.Clouds are common on Earth but they cover completely Venus\' atmosphere. They are made of sulfuric acid droplets at 50-70 km above the surface and at temperatures comparables to Earth\'s surface temperatures. They are extremely reflective making Venus the most reflecting body in the Solar System. | |

Explain water cycle with draw |
| Answer» The whole process in which water evaporates and falls on the land as rain and later flows back into the sea via rivers is known as the water-cycle. The organisms get water from and return it to the global water cycle. Plants absorb water from the soil or water reservoir and add it to the air in vapour form by a process called transpiration. Water transpired by trees cools the surrounding air. Animals take water from the water reservoir or with food and return it to the air and vapours by respiration or to the soil by excretion. Mammals also excrete water as sweat which evaporates from the water bodies. Water is added to the environment by the death and decay of organisms. Water vapour formed by transpiration and respiration form clouds and enters global water cycle. Rain adds water to the soil and reservoir for reuse by plants and animals. This completes the water cycle. | |

ear |
| Answer» The ears are the sense organs which help us in hearing sound. It consists of three compartments – outer ear, middle ear and inner ear. \tThe outer ear consists of a broad part called pinna having a long passage called ear canal. At the end of the ear canal is a thin, elastic and a circular membrane called ear drum. It is also called tympanum. The outer ear contains air.\tThe middle ear contains three small and delicate bone called hammer, anvil and stirrup. These bones are linked to one another. The middle ear transmits the amplified pressure variations received from the sound wave to the inner ear. \tIn the inner ear, the pressure variations are turned into electrical signals by the cochlea. These electrical signals are sent to the brain via the auditory nerve, and the brain interprets them as sound. | |

Give the mass number of x and y what is the relation between the two species ? |
| Answer» Mass number = No. of protons + No. of neutronsSo, Mass number of X = 6 + 6 = 12 Mass number of Y = 6 + 8 = 14Thus, the mass number of X is 12 and that of Y is 14. Now , X contains 6 protons, therefore, the atomic number of X is 6. Y contains 6 protons, therefore, the atomic number of Y is also 6. Since X and Y have the same atomic number (of 6) but different mass numbers (of 12 and 14) , they are a pair of isotopes. Atomic number 6 is of carbon element. So, both X and Y represent carbon element. | |
