    The source of information for making proteins is generally stored in
    The information to make proteins is stored in an organism`s DNA. Each protein is coded for by a specific section of DNA called a gene. A gene is the section of DNA required to produce one protein.

    Pituitary gland, pineal gland and hypothalamus are located in which part of the human body?
    The pituitary gland or hypophysis is a small gland about 1 centimeter in diameter or the size of a pea. It is nearly surrounded by bone as it rests in the sella turcica, a depression in the sphenoid bone. The gland is connected to the hypothalamus of the brain by a slender stalk called the infundibulum.

    The near point of a hypermetropic eye is 1m. The power of the lens required to correct this defect is
    In the problem, it is given that the near point of defective eye is 1 m and that of a normal eye is 25 cm. Hence u=−25 cm. The lens used forms its virtual image at near point of hypermetropic eye i.e., v=−1m=−100 cm. Using lens formula, we have :- v1​−u1​=f1​−1001​−−251​=f1​f=3100​=0.33mpower=f(inmetres)1​=+3.0D

    Which of the following is used as a lubricant?
    Graphite is structurally composed of planes of polycyclic carbon atoms that are hexagonal in orientation. The distance of carbon atoms between planes is longer and therefore the bonding is weaker. Graphite is best suited for lubrication in air. It is a mineral made of loosely bonded sheets of carbon atoms, giving it a slippery texture that makes it a very effective lubricant. This slippery quality also makes graphite a good material for pencil lead because it easily sloughs off onto paper. Graphite is bonded by covalent bond, thus, it is helf by weak intermolecular forces. Since it has weak intermolecular forces, graphite would be slippery and soft enough to act as a lubricant.
