Solutions

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

S2.Ans. (c)
Sol. Conservation of momentum in a collision between particles is dependent on both Newton’s second law of motion and Newton’s third law of motion.

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. Gravitational force is an imaginary force pulling everything towards the earth surface without any contact to the object.

S8.Ans. (b)
Sol. Collenchymas provides malleability and flexibility to certain parts of the plants. Parenchyma is considered to be the soft tissue which makes most of the cell and sclerenchyma is the dead tissue which makes up fibre and provides rigidity to the cell.

S9.Ans. (c)
Sol. Blood plasma cells form 55 – 60% by volume of blood. Antibodies and some other substances such as lysozyme and properdin always occur in the plasma. They serve to destroy bacteria, viruses and toxic substances that may enter into the blood from outside or from body tissues.

S10.Ans. (b)
Sol. The force between protons and neutrons in the nucleus is short range strong interaction.
