which are formed inside the living being against a specific antigen.
5. What will happen if we provide O+ve blood to an Ove person at first time ?
A. No effect i.e. the person can survive because antibodies are not formed in sufficient amount against
inserted antigen.

11. Why cant restriction enzyme cut its source DNA ?
A. Restriction enzymes cant cut bacterial or source DNA because it is methylated.
12. Why does the people live at high altitude have reddish skin ?
A. Because at high altitude atmospheric pressure is low in compare to plane area and haemoglobin is not
able to bind with sufficient O2. So number of R.B.C. (amount of Hb) increase to make balance in the body
state.
13. Why the plant cloning is easier than animal cloning ?
A. Because plants have more totipotent cells in compare to animals.

& Parthenocarpy are the terms which are used for it.
24. If sexual reproduction was removed from the entire living world , what will be the consequence in the term
of evolution ? (when mutation is also absent ).
A. If sexual reproduction was removed from the entire living world there would be no variation and no new
species will be formed. However variation is necessary for evolution & therefore evolution will stop.

A. When female anopheles sucks the human blood, it inserts its saliva in human blood to stop clotting thus
Plasmodium which is present in the salivary gland of mosquito released in human body.
26. Why do the water bodies get polluted by loading of nutrients ?
A. Due to excessive of nutrients there will be high growth of algae at water surface which is known as
eutrophication. Due to the exceed growth, Algae make a physical barrier between atmosphere &
hydrosphere . So light & gases are unable to insert in hydrosphere and there will be no photosynthesis as
well as no liberation of O2 & due to absence of O2 all the plants & animals will die thus the water body get
polluted.
27. A farmer floods his field every day thinking that watering in this manner will result in a better yield of his
wheat crop. What will be the result of this action of the farmer ?
A. The soil is likely to get water logged which is unfit for the growth of wheat plants.
28. Why insectivorous plants catch insects ?
A. These plants grow in N2 deplete area so to get N2 they catch insect & digest their body protein to form their
own proteins.
29. Why some animal show hibernation ?
A. Cold blooded animals are unable to adjust their body temprature in variable environment. To survive in low
temprature they under go in long winter sleep where they minimize their metabolism & utilize rest of the
energy to warm up their body.
30. Why the wall of ventricle is thicker than auricle ?
A. Because ventricle have to supply the blood in whole body parts while auricle have to receive blood.
31. Why do we feel high temprature in grainery ?
A. Grains are stored in grainery. They do respiration in which energy is librated out as heat that raise the
temprature of grainery.
32. Where should wax applied in a submerged plants leaf to slower the transpiration rate ?
A. No need of it because they have inactive stomata & submerged plants cant do transpiration.
33. Why salt is used in pickle as preservative ?
A. Because of salt, the solution become hypertonic where microbes get plasmolysed & pickle can be
preserved.
34. What will happen if we apply the wax on an insects body surface ?

35. Why the plants leaves fall in autumn ?
A. Because vascular tissue is blocked due to callose deposition & simultaneously ABA concentration will
raise which form abscission layer at the base of leaves.
36. What will happen if we provide another stimulus before the ending of previous stimulus ?

37. Why does a drunker stumble ?
A. Alcohal affect the cerebellum which make the balance during walking.
38. Haemoglobin bind with O2 but this process is not called oxidation, why ?
A. Because in haemoglobin Fe present in Fe+2 state after addition of O2 there is no change in the oxidation
number of Fe so its not oxidation.This is called oxygenation process.
39. Why vein appear blue in colour ?
A. Because it reflect blue colour of light.
40. How can insect survive after sucking various kind of blood groups blood ?
A. Because in insects the blood goes to digestive tract where it is digested but in human it insert into
circulatory system.
41. What is rigor mortis ?
A. During muscle contraction actin binds with myosine and form actomyosin. But for the muscle relaxation,
ATP is required to break the bonding of actomyosine. After death ATP is not available, so the muscles
found in contracted position and this phenomenon is known as rigormortis.
42. Why cant lysosomes digest its own wall although it is known as sucidial bags ?
A. Lysosome contains hydrolytic enzyme which are functional only in the persence of H2O . But inside the
lysosome H2O molecules are not available so they are inactive.

companion cell by means of this companion cell control the whole activity of sieve cells.
48. A certain tissue in a green plant somehow gets blocked and the leaves wilted. What was the tissue that
got blocked ?

KVPY Interview Workshop
KVPY stage-1 results have been declared and more than 500 students from across the India have qualified for its interview round ,which is scheduled after Jan.20'2010.
KVPY is an examination conducted by Indian Institute of Science, Bangalore & founded by the Department of Science and Technology of Government of India. The main objective of the examination is develop the interest of the students in the research work in the field of Science & Technology.
KVPY interview is a very different from the other interviews. This is technical one and questions are asked related to derivation of fundamental laws & experimental examples.
So to prepare students for the Interview Session of KVPY, Resonance premiere institute for competitive exam has announced workshop for interview preparation. The workshop will expose to students to generally asked fundamental concept questions to develop their Research & Development potential.
