Class10 – Life Process- biology Class10 - Life Process- biology Mock Test. This Test Consist of 20 QuestionsTotal Time - 20 -Minutes 1. Choose the correct answer from the alternatives given.In an one-circuit circulatory system, blood pressure: is constant throughout the system cannot be determined drops significantly after gas exchange has taken place is higher at the intestinal capillaries than at the gill capillaries None 2. Which of the following statements is/are correct?i) All green plants can prepare their own food.ii) Most animals are autotrophs.iii) Carbon dioxide is not required for photosynthesis.iv) Oxygen is liberated during photosynthesis.Choose the correct answer from the options below (ii) only (ii) and (iii) (i) and (iv) (i) and (iii) None 3. Incomplete double circulations is found in: 4. Blood pressure in the veins is lower than that of arteries. The best hypothesis to explain this is that Capillaries offer resistance to the blood flow Veins are farther from the heart Veins have thinner walls than arteries Most veins carry blood up-hill None 5. Utilization, rearrangement, and decomposition of complex organic matter, known as 6. People suffering from high blood pressure should take which of the following precautions to avoid an excessive rise in their blood pressure? Sleep as much as possible Increase their body weight Avoid standing Avoid emotional disturbances and excitement None 7. Given is an animal followed by three terms or features. Choose the term which does not match with the animal.Amoeba. None of the above Tentacle Food vacuole Nucleus None 8. The fluid present between the blood capillaries and the cell membrane, through which gasses, nutrients, and metabolic wastes are exchanged between the blood and the cells are called as: 9. Pancreatic amylase acts on 10. Plant X is a vascular and invasive plant species that grows densely over the surface of a lake at a very high rate, due to pollution in water. It has been linked to oxygen depletion of the water, in spite of the fact that it is photo-synthetic.Which of the following accounts for this contradiction? None of these Because X is highly invasive, it incorporates a large quantity of oxygen in its biomass While being photosynthesis, X consumes oxygen at a faster rate than it releases the same, because of its high rate of growth When X dies, the bacteria that decompose its dead body consume the oxygen dissolved in water and grow rapidly None 11.

A student poured alcohol on a plant continuously for a long time. Why can the plant not prepare its own food? Alcohol absorbed all the food prepared by the plant. Alcohol dissolved all the minerals present in the plant. Alcohol dissolved chlorophyll present in the plant Alcohol does not let the plant to absorb carbon dioxide from the air. None 14. Which one of the following helps in the upward movement of water and dissolved minerals from the roots to the leaves through the stem ? transpiration transaction translocation transportation None 15. Choose the correct pair of sentences that are true to photosynthesis (i) Sunlight, carbon dioxide, chlorophyll and water are necessary.(ii) Oxygen is absorbed.(iii) Leaves carry out photosynthesis.(iv) Proteins are made during photosynthesis. (iii) and (iv) (i) and (iii) (i) and (iv) (ii) and (iv) None 16. 'The master chemists of our body are the kidneys'. Justify the given statement. Kidneys eliminate all chemicals absorbed by the body Kidneys filter all chemicals in the body. Kidneys store the chemicals accumulated in the body. Kidneys maintain the chemical composition of blood. None 17. A transport system is needed to transport(i) Nutrients, oxygen and hormones from the place, they are absorbed or received to the cells.(ii) Waste products from the place they are formed to the place from where they are eliminated outside.(iii) Heart beat, chromosome. (i) and (ii) correct (ii) and (iii) correct (i) and (iii) correct (i) , (ii) and (iii) correct None 18. Consider the following statements.(a) In muscles, anaerobic respiration produces carbon dioxide, water and energy.(b) Artificial kidney is a device to remove nitrogenous waste products from blood through dialysis.(c) Food is translocated inside the plants through phloem.Which of the above statements are correct? a and c b and c a and b None of the above None 19. Oxygen liberated during photosynthesis comes from? 20. Which of the following statements is/are true(T) or false(F) regarding nutrition in organisms?(i) Photosynthesis also occurs in leaves having colors other than green.(ii) The process of photosynthesis first produces a simple carbohydrate called glucose which then gets converted into a complex carbohydrate called starch.(iii) Cuscuta is a yellow-colored plant but it can synthesize its own food by photosynthesis.(iv) In a symbiotic association, Rhizobium bacteria derive their nutrition from fungus.
