Answer» BSE Class 10 Science (086) - Deleted portion (Theory):Unit I: Chemical Substances - Nature and Behaviour ChapterTopicsMetals and Non-metalsBasic metallurgical processes; Corrosion and its prevention.Carbon CompoundsNomenclature of carbon compounds containing functional groups (halogens, alcohol, ketones, aldehydes, alkanes and alkynes), difference between saturated hydro carbons and unsaturated hydrocarbons. Chemical properties of carbon compounds (combustion, oxidation, addition and substitution reaction). Ethanol and Ethanoic acid (only properties and uses), soaps and detergents.Unit II: World of Living ChapterTopicsControl and co-ordination in animals and plants(Whole Chapter Removed)Tropic movements in plants; Introduction of plant hormones; Control and co-ordination in animals: Nervous system; Voluntary, involuntary and reflex action; Chemical co-ordination: animal hormonesHeredity and EvolutionBasic concepts of evolutionUnit III: Natural Phenomena ChapterTopicsThe Human Eye and the Colourful WorldFunctioning of a lens in human eye, defects of vision and their corrections, applications of spherical mirrors and lensesUnit IV: Effects of Current ChapterTopicsMagnetic Effects of Current :Electric Generator, Direct current.Alternating current: frequency of AC, Advantage of AC over DC.Domestic electric circuitsUnit V: Natural Resources ChapterTopicsSources of Energy(Whole Chapter Deleted)Different forms of energy, conventional and non-conventional sources of energy: Fossil fuels, solar energy; biogas; wind, water and tidal energy; Nuclear energy. Renewable versus non-renewable sources of Energy.Management of Natural Resources(This chapter is to be prepared only for Internal Assessment.
