(a) can immediately adjust itself to land on all four paws and bend the legs to absorb the impact of falling
(b) has elastic bones
(c) has thick and elastic skin

Solutions

S1.Ans. (a)
Sol. Raw mangoes shrivel when pickled in brine due to osmosis i.e. flow of water from higher concentration to lower concentration through a semi-permeable membrane.

S2.Ans. (a)
Sol. Ice under black wrap will melt easily because dark colour (black) absorbs the most of light energy falling on it.

S3.Ans. (b)
Sol. Barium is a good absorber of X-rays and helps stomach to appear clearly.

S4.Ans. (b)
Sol. The hollow bricks provide thermal insulations; the air in hollow bricks, does not allow outside heat or cold in the house to go out or come in the house. So, it keeps house cool in summer and warm in winter.

S5.Ans. (a)
Sol. As the cat falls from a height, it bends the legs to absorb the impact of falling and immediately adjust itself.

S6.Ans. (a)
Sol. The Oxygen rich blood from lungs comes to the heart in left atrium, the left chamber of the heart.

S7.Ans. (d)
Sol. A gigabyte is a unit of data storage capacity that is roughly equivalent to 1 billion bytes.

S8.Ans. (c)
Sol. Plastid is a double-membrane organelle found in plants, algae, and some other eukaryotic organisms. They are of different types such as chloroplasts, chromoplasts, gerontoplasts, & leucoplasts (used for storing starch and fats).

S9.Ans. (a)
Sol. The endoplasmic reticulum bearing ribosomes on their surface called rough endoplasmic reticlum (RER) which are actively involved in protein synthesis. The smooth endoplasmic retriculum (SER) is the major site for synthesis of lipid. In animal cells, steroidal hormones syntherized in SER.

S10.Ans. (b)
Sol. Ammonia (NH3) obtained from different sources always has same proportion of Nitrogen and Hydrogen and it proves the validity of law of constant proportion.
