(a) an acceleration

Solutions

S1.Ans. (b)
Sol. The sex of a fetus is determined by father as male parent provides gamete X and Y, while female parent provides only X. If gamete Y from father fuses with X from mother it will produce male while if gamete X from father fuses with X from mother it will produce female, hence it is the father who is responsible for the sex of the baby.

S2.Ans. (d)
Sol. DNA is responsible for controlling hereditary characters of the living cells.

S3.Ans. (a)
Sol. Gene is the functional unit of inheritance which controls the transmission and expression of one or more characters. It does so by specifying the structure of a particular protein. Genes are generally composed of deoxyribonucleic acid (DNA), except in some viruses where it is composed of ribonucleic acid (RNA).

S4.Ans. (b)
Sol. Protoplasm is the whole content of a cell enclosed within the cell membrane, including both the cytoplasm and nucleus.

S5.Ans. (a)
Sol. The law is named after Amedeo Avogadro who, in 1811, hypothesized that two given samples of an ideal gas, of the same volume and at the same temperature and pressure, contain the same number of molecules.

S6.Ans. (a)
Sol. High-altitude cooking is the opposite of pressure cooking in that the boiling point of water is lower at higher altitudes due to the decreased atmospheric pressure. This may require an increase in cooking times or temperature and alterations of recipe ingredients.

S7.Ans. (a)
Sol. In Earth’s atmosphere nitrogen is most abundant while oxygen is the second most abundant.

S8.Ans. (a)
Sol. As a certain impulse applied for a short time will give a large force so the chinaware breaks into pieces. Therefore, chinaware is wrapped in straw of paper while packing so that the event of fall (impact) will take a longer time to reach the chinaware through straw of paper and hence the average force exerted on the chinaware is small and chances of its breaking reduce.

S9.Ans. (d)
Sol. For both stationary and moving objects with unchanging speed and direction, all the forces acting on the objects are in balance with each other, i.e. they all cancel each other.

S10.Ans. (a)
Sol. If the train were moving with uniform velocity, the coin would fall back to the passenger’s hand. While, if the train is accelerated, the horizontal velocity of the train would be more than that of the coin by the time the coin returns. Therefore, the train travels a greater horizontal distance than the coin and coin falls behind the passenger.
