°Thioridazine hydrochloride‚USP. Is a member of the piperizine subgroup of the phenothiazines. Thioridazine occurs as a white or slightly yellow‚ crystalline or micronized powder‚ which is odourless or has a faint odor and is practically insoluble in water and freely soluble in dehydrated alcohol. The drug has sedative and hypotensive activity in common with chlorpromazine and less antiemetic activity. thioridazine is indicated for the treatment of schizophrenic patients who fail to respond

Pure aluminium is a relatively soft‚ silvery white metal. When exposed to air‚ a thin coating of Aluminium oxide gives it a dull lustre. It is three times less dense than water‚ and has great strength when alloyed‚ it doesnt rust and has high electrical conductivity‚ and Aluminium is also ductile‚ making it a very useful metal. Aluminium readily makes alloys with copper‚ zinc‚ magnesium‚ manganese and silicon. Aluminium foil is 92-99% pure aluminium. Other uses of aluminium alloys include computers

OBJECTIVES The Basis of Heredity 1. Explain in general terms how traits are transmitted from parents to offspring. An organism’s traits and appearance are controlled by specific forms of proteins contained in DNA. When gametes are formed‚ the male and female parents pass along their DNA into their respective gametes. Fertilization fuses the gametes and combines the genetic contribution of each parent into the new offspring. 2. Distinguish between asexual and sexual reproduction. Asexual Reproduction-A
