Solution

13. A. hinge joint

Reason: Elbow joint is a type of synovial hinge joint.

14.B.Xylem

Reason: Xylem is the vascular tissue that transports water and minerals from roots to upper parts of the plant.

15.D.Cambium

Reason: Cambium present between the vascular tissue divide to give more strength and support to the stem.

16.C.Transpiration

Reason: Through transpiration water is puled up from roots to the underside if leaves to go out into the atmosphere as water vapour.

17.C.Cold climates

Reason: Xerophytic conditions means extreme hot or extreme cold.

18.C.Erythrocytes

Reason:RBCs or erythrocytes contain hemoglobin that carries oxygen in the body.

19.A.haemoglobin

Reason:Hemoglobin is the red pigment present in RBCs.

20.D.Glycogen

Reason: Glycogen is a polysaccharide.

21.B.II

Reason: II part represents pancreas that secretes insulin.

22.C.liver

Reason: Insulin acta mainly on liver.

23.A.Growth of plant towards light.

Reason: Phototropism refers to growth of plan towards the direction of light.

24.B.molars

Reason: Molars are used for grinding purpose.

25.A.1-2

Reason: pH of stomach is between 1.5 to 3.5

26.C.The uptake of digested food into the blood.

Reason: The process of absorption of food takes place in the wall of small intestine into the bloodstream.

27.C.There were differences between giant tortoises on different small islands.

Reason: The above observation in the galapagoes island made Darwin formulate theory of evolution.

28.C.Chordata

Reason:Birds belong to phylum chordata and subphylum vertebrata.

29.D.Homo is the genus and sapiens is the species.

Reason: According to binomial classification, first name is of genus and second of species.

30.C.Carbon dioxide

Reason: Carbon dioxide absorbs the heat that is radiated back into the atmosphere causing global warming.
