Explain spectrum and dispersion briefly |
| Answer» Dispersion—The splitting of white light into its component colours is known as dispersion. White light contains many wavelengths ( it contains lights of many wavelengths(colours)).Since their wavelengths are different, their speeds are different in a medium, but in vacuum all the wavelengths travel with the same speed. In a material medium, the speed of different wavelengths are diferent. So when a beam of white light passes through a medium, the material medium splits the white light into different components. This phenomenon is called dispersion.\xa0Spectrum-The band of the coloured components of a light beam is called its spectrum. | |

What is cerebral reflex actions |
| Answer» Reflex actions are sudden involuntary responses which does not involve thinking. For example, when we touch a hot object, we withdraw our hand immediately without thinking. The sensory nerves that detect the heat are connected to the nerves that move the muscles of the hand. Such a connection of detecting the signal from the nerves and responding to it quickly is known as reflex arc. Reflex arcs are formed in the spinal cord and the information reaches the brain and brain responses to it. | |

What is turgor movement ? Which organism show turgor movement |
| Answer» Turgor movement is due to the difference of turgidity of the cells in the lower half and upper half of pulvinus (petiole of leaf). When leaf of touch-me-not plant (Mimosa pudica) is touched, the electrical signal send chemical signals from leaflets to pulvinus (petiole) of leaf. Cells in the lower half of pulvinus lose water and become flaccid, while cells in the upper half of pulvinus become turgid due to accumulation of more water. Hence, leaf droops down for a short time. | |

What is difference between strong acid and weak acid |
|
Answer» Some of the, when dissolved in water, get almost completely dissociated to provide hydrogen ions. These acids are known as strong acids.Ex: HNO3, H2SO4, etc.On the other hand, there are some acids which when dissolved in water, are only incompletely dissociated to give hydrogen ions. These are called weak acids.Ex: H2CO3, CH3COOH, etc. strong acid produce more H+ ions when dipped in water but mineral acid (weak acid) show less H+ ions in water solution Strong acids dissociate fully and produce H+ ions when mixed with water.... Whereas weak acid dissociate partially.. |
