Solutions

S1.Ans. (c)
Sol. Nucleus, cell membrane, mitochondria and cytoplasm are present in animal cells.

S2.Ans. (c)
Sol. The average life span of human RBC is 120 days. It’s life span is much more than WBC and Platelets.

S3.Ans. (d)
Sol. Telophase is the stage where cytokinesis usually occurs in animals, which means the cell divides into two daughter cells and is identical to each other.

S4.Ans. (c)
Sol. Mostly dicotyledonous plants exhibit an increase in girth called the secondary growth. The tissues involved in secondary growth are the two lateral meristems: vascular cambium and cork cambium.

S5.Ans. (a)
Sol. The liquid surface always acquires minium surface area due to surface tension so, the small droplet of any liquid is always spherical.

S6.Ans. (a)
Sol. Meson are sub-atomic particles composed of a quark and an antiquark. Its existence was theoretically predicted by Jakense physicist-Yukawa Hideki, but it was first discovered by English physicist civil Frank Powell in 1947 in cosmic-ray particle interactions. All meson are unstable having lifetimes ranging from 10-8 to less than 10-22 second.

S7.Ans. (b)
Sol. Natural radioactivity was discovered by Henri Becquerel in 1896 by using naturally fluorescent minerals to study properties of X-rays.

S8.Ans. (b)
Sol. Baking soda is sodium bicarbonate with chemical formula NaHCO3. It is primarily used in baking industries as a leavening agent.

S9.Ans. (b)
Sol. The solids in which the constituent particles of matter are arranged and organized in a specific manner are called Crystalline Solids. These solids contain crystals in their structure and each crystal has definite geometry. The sharp freezing point is found in crystalline solids. This is because the distance between same atoms/molecules or ions is same and remains constant.

S10.Ans. (d)
Sol. Torque is the cross product of force and perpendicular distance to an axis of rotation. The torque produced by a force depends on the magnitude of the force, the direction of the force, the point of application of the force relative to origin.
