| 21. The water vapour present in the air comes in contact with cold surface of the glass, loses its energy and gets converted into droplets of water. |
| 22. Particles in the air, if fuel with higher temperatures, acquire high kinetic energy, which aids them to move fast over a stretch. Hence, the smell of hot sizzling food reaches a person even at several meters. |
| 23. The Golgi apparatus consists of stacks of membrane-bound vesicles whose functions are as follows:- Storage of substances, Packaging of substances, Manufacture of substances Without the Golgi apparatus, the cells will be disabled from packing and dispatching materials that were produced by the cells. The Golgi apparatus is also involved in the formation of cells. Hence, in the absence of the Golgi apparatus, cells will not be produced. |
| 24. The acceleration due to gravity does not depend upon the mass of the stone or body. Both the bodies fall with the same acceleration towards the surface of the earth. Thus a big stone will fall with the same acceleration as a small stone. So, both the stones will reach the ground at the same time when dropped simultaneously. |
| 25. The universal law of gravitation states that every object in the universe attracts every other object with a force called the gravitational force. The force acting between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. |

| 27. a. 0°C=273K 300K= (300-273)°C = 27°C b. 573K= (573-273)°C = 300°C |
| 28. No,because there is no atmosphere on the moon. 100 x 60=6000/min |
| 29. Solid frozen carbon di oxide is called dry ice.When the pressure is reduced co2 directly transform into gaseous state without first passing through a fluid state. |
| 30. Diagram of different types of muscles and difference. |
| 31. (i) Difference between manure and fertilizer (ii) Cross-breeding is generally the best method adopted for improving cattle breed quality. In this method, breeding between two good cattle breeds results in a new, improved variety of cattle breeds or offspring. While breeding, care is taken to have a good resultant with a high yield having resistance to climatic conditions. |
| 32. FeSO4, NaCl, H2SO4 |
| 33. (i) Mitochondria are known as the powerhouse of the cell. It is because it releases the energy required for different activities of life. Mitochondria releases energy in the form of ATP (Adenosine triphosphate) molecules, essential for numerous chemical activities of life. Hence, ATP is often referred to as the ‘energy currency of the cell’. (ii) When there is damage to the cell and when revival is not possible, lysosomes may burst, and the enzymes digest their own cell. Consequently, lysosomes are known as suicide bags. |
Section-D |
| 34. (a) (i) The atomic number of an atom is the same as the number of protons in that atom; hence, its atomic number is 8. Uses of isotopes: - (i) The isotope of the Iodine atom is used to treat goitre, an iodine- deficient disease. (ii) In the treatment of cancer, an isotope of cobalt is used. (iii) Fuel fornuclear reactors is derived from the isotopes of the Uranium atom. |
