4 6 Question numbers 4 to 6 in Section-B are questions based on practical skills are two marks questions. SECTION-A Name the protein present in the muscles which is responsible for movement. Under what condition will the magnitude of the displacement be equal to the distance travelled by an object? Mention the requirements for different crops to complete their life cycle? When a beam of light was passed through a mixture of milk and water, the path of light was clearly visible. Explain why this happens and name the phenomenon. The above - mentioned phenomenon is also observed in dense forests. Explain how it occurs there. How does endocytosis help an organism like amoeba? 6 Derive the Newton s first law of motion from the mathematical expression of the second law of motion. 7 Explain by an activity that different states of matter have varied force of attraction between the Particles.

8 Differentiate between simple distillation and fractional distillation. What is the function of beads in fractionating column used in fractional distillation? 9 Rahul was a good player, but his sports teacher observed that he takes drugs. Rahul denied this. Then the sports teacher asked him to go for blood test. Answer the following questions. Name the technique that can be used to detect the presence of drugs in blood. Write any other application of this technique. Which values in Rahul s personality are reflected in his behaviour? How will these values affect his reputation and future prospectus in sports and as an individual? 0 Differentiate between the three types of muscular tissues. (e) (f) Identify the type of tissues in the following : Vascular bundle Inner lining of the intestine Lining of kidney tubule Iris of the eye (e) Muscles of the heart (f) Bronchi of lungs Page of
7.x0 kg.7x0 6 m (G=6.7x0 - Nm kg - ). State how is gravitational force between two bodies related to their masses. Mass of moon is 7.x0 kg and its radius is.7x0 6 m. Determine acceleration due to gravity on its surface. (G=6.7x0 - Nm kg - ). A B C A frog hops from point A to point B, along a straight line path and then turns and hops to point C. What is the distance travelled by the frog? What is the magnitude and direction of displacement? 4 Which is a more fundamental quantity - The mass of a body or its weight? Why? Can a body has mass, but no weight. Give seasons for your answer. Page 4 of
How would you arrive at a mathematical formula to measure force using Second Law of Motion? Define the unit of force using this formula. 6 Define hybridization. How is it useful for crop variety improvement?? 7 8 List two advantages of using fertilizers in crop fields. State why excessive use of fertilizers is con harmful.? Define hybridization. How is interspecific crossing different from intervarietal crossing. 9 List three characteristics of particles of matter. When we add some sugar or salt in a beaker containing water, after sometime the sugar or salt becomes invisible. Where does it go? What property of particle of matter does it show? How will you justify that ice water and steam are the three states of a substance and not different substances? 0 Page of
(iii) Differentiate between homogeneous and heterogeneous mixtures. Give an example of each of the following (iii) Solid-solid homogeneous mixture Solid-Liquid heterogeneous mixture Liquid Liquid heterogeneous mixture (iii) Give reason for the following : The cells of meristematic tissue have dense cytoplasm, thin walls and prominent nuclei. Vacuoles are absent in the cells of this tissue Identify the type of meristem present in the following : - at the base of leaves girth of stem increase due to this (iii) increases the length of the stem u t a v m/s s 0m/s (V u at) An object starts a linear motion with velocity u and with uniform acceleration a it acquires a velocity v in time t. Draw its velocity-time graph Obtain Ist equation of motion, V u at, for velocity time relation by using velocity time graph. Page 6 of
