36. Sheema was asked to prepare four separate mixtures in four beakers A, B. C, D by mixing
sugar, fine sand, thin paste of starch and chalk powder respectively in water and then
categories each as stable or unstable. What will be the correct categorization?

Section A
1. Lignin.
2. Uniform motion.
3. Crop rotation.
4. The mixtures in which particles are uniformly distributed are called homogenous and one
without uniform distribution of particles is called heterogeneous mixture.
5. Weight = mass x acceleration due to gravity.


6. Mitochondria is a double membrane structure that release energy in form of ATP. Plastid is
semi- autonomous structure that provide colour to the plant parts.
7. a) Sponge can be compressed easily although it is a solid because the air space present
between the sponges comes out when compressed and return back as soon as the force is
released.
b) Naphthalene is a sublime substance that changes into vapour at normal room
temperature. So, when kept in open it get disappeared.
8. Mass of solute = 12 g.
Mass of solution = 160 g
Concentration of solution = 12/160* 100%

9. Meristem tissue is responsible for growth and elongation of the plant root and shoots. They
also increase the girth of stem and root by secondary growth. They are living cells and
faster growing.

10. (a) Stone has more inertia.
(b) Train has more inertia.
11. Inertia depends upon the force by which object is attracted towards it earth surface.
12. The loaded truck will need larger force to stop as the momentum of loaded truck is more
than the momentum of empty truck. Momentum depends upon mass and velocity of the
moving body.
13. Both the body A and B will be attracted by same force by the earth. As the acceleration due
to gravity depends upon the mass and radius of the earth and not on the mass of the body
itself.
14. Phloem tissue carries food prepare in leaves to all other parts of the plant. On the other
hand xylem tissue transports water and mineral from root to leaves.
Phloem transport is bidirectional but xylem transport unidirectional.


16. Old and worn out parts are removed by the lysosomes. It contain strong digestive enzyme
that hydrolyses the old and worn out tissues. The number of lysosomes vary from cell to
cell.
17. The two factors that are responsible for the food grain during storage are
Biotic factors that include mites, rodents, bacteria, fungi etc.
Abiotic factors that include sunlight, moisture, temperature, rain etc.
During storage, fumigation and spraying with insecticides prevents the seed.
18. An object remains in state of rest or uniform motion on straight line until a force is applied
over it.
Dust comes out when carpet is beaten with stick because of inertia of rest. On beating carpet
comes in motion but dust particles remain in state of rest and come out.

19. (a) Evaporation is the process of changing water into water vapour with attaining the
boiling point. The factors that help in evaporation include:
(i) Surface area
(ii) Humidity
(iii) Temperature
(iv) Pressure
(b) Evaporation causes cooling because the energy required for evaporation is taken from
the surface from where evaporation is taking place.
20. (a) Balanced force
(b) Unbalanced force
(c) Unbalanced force
(d) Balanced force.
21. Newton’s second law of motion states that the force acting on body is directly proportional
to the product of mass and acceleration.
Force = mass x acceleration.
F= m x a
SI unit of force is Newton. One Newton is the force that displace a body of mass 1 kg to a
distance of 1 meter.
22. Desirable traits used in varietals improvement in poultry farming are:
a. Higher yield- to get more production by less investment.
b. Improved nutritional quality – Food grain contain more protein and carbohydrates
than the traditional one.
c. Resistance to disease- The new variety should be resistance to various bacterial and
fungal diseases.
d. Wide range of adaptablity- The new crops must be grown in any kinds of soil
combination and climatic conditions.
23. (i) Cardiac muscles are involuntary, striated and non-fatigue muscles which is located in the
walls of heart to perform rhythmic contraction and relaxation throughout life. The cells are
uninucleate, small and cylindrical with broad ends.
(ii) The tissue which is under the control of will and work as per the requirement of body is
striated or skeletal muscular tissue. They are voluntary in nature.
(iii) Ligaments are cord likes dense yellow fibrous connective tissue of considerable
strength and high elasticity. They bind a bone with another bone. Because of elasticity a
ligament allows bending and rotation of over joint.
24. (a) When sugar is dissolved in water, its crystals breaks into tiny particles. The sugar
particles go into the spaces between the particles of water and mix with them to form sugar
solution. The sugar particle occupies the space between water particles.
From the dissolution of sugar in water, we infer that
(i) The matter consisting of sugar and water is made up of small particles.
(ii) The particles of matter have space between them.
Section B
25. (b)
26. (a)
27. (a)
28. (b)
29. (d)
30. (a)
31. (a)
32. (d)
33. (b)
34. Thermometer used for measuring the melting point of ice is laboratory thermometer. The
two precaution includes
a. Thermometer knob should not touch the bottom.
b. Ice should be perfectly crushed.
35. After solid start melting the temperature remain constant until all the solid get melted
because the energy is used to overcome the latent heat of fusion and in breaking the strong
intermolecular force of attraction.
36. The mixture in beaker A and C will be stable.
The mixture in beaker B and D will be unstable.
