sir I have a doubt If Lok Sabha has dissolved after a joint sitting has been called, then what are the circumstances under which that joint sitting would still be held?

  6. Species interdependence in nature confers many benefits on the species involved, but it can also become a point of weakness when one species involved in the relationship is affected by a catastrophe. Thus, flowering plant species dependent on insect pollination, as opposed to self-pollination or wind pollination, could be population endangered when the of insect-pollinators is depleted by the use of pesticides. In the forests of New Brunswick. e.g., various pesticides have been sprayed in the past 25 years in efforts to control the spruce budworm, an economically significant pest. Scientists have now investigated the effects of the spraying of Matacil, one of the anti-budworm agents that is least toxic to insect-pollinators.


  7. They studied Matacil's effects on insect mortality in a wide variety of wild insect species and on plant fecundity, expressed as the percentage of the total flowers on an individual plant that actually developed fruit and bore seeds. They found that the most pronounced mortality after the spraying of Matacil occurred among the smaller bees and one family of flies, insects that were all important pollinators of numerous species of plants growing beneath the tree canopy of forests. The fecundity of plants in one common indigenous species, the red-osier dogwood, was significantly reduced in the sprayed areas as compared to that of plants in control plots where Matacil was not sprayed. This species is highly dependent on the insect-pollinators most vulnerable to Matacil. The creeping dogwood, a species similar to the red-osier dogwood, but which is pollinated by large bees, such as bumblebees, showed no significant decline in fecundity. Since large bees are not affected by the spraying of Matacil, these results add weight to the argument that spraying where the pollinators are sensitive to the pesticide used decreases plant fecundity.


  8. The question of whether the decrease in plant fecundity caused by the spraying of actually causes a decline in the overall population of flowering plant species still remains unanswered. Plant species dependent solely on seeds for survival or dispersal are obviously more vulnerable to any decrease in plant fecundity that occurs, whatever its cause. If, on the other hand, vegetative growth and dispersal (by means of shoots or runners) are available as alternative reproductive strategies for a species, then decreases in plant fecundity may be of little consequence. The fecundity effects described here are likely to have the most profound impact on plant species with all four of the following characteristics: a short life span, a narrow geographic range, an incapacity for vegetative propagation, and a dependence on a small number of insect-pollinator species. Perhaps we should give special attention to the conservation of such plant species since they lack key factors in their defences against the environmental disruption caused by pesticide use. pesticides


  9. Q.1 Consider the following statements regarding the plant species called creeping dogwood in the passage 1. It grows primarily in regions that were not sprayed with pesticide, and so served as a control for the experiment. species 3. It is similar to the red-osier dogwood, but its insect pollinators are known to be insensitive to the pesticide used in the study. 4. Its geographical range is similar to that of the red-osier dogwood, but the latter species relies less on seeds for reproduction. Which of the above statement(s) is/ are correct, as per the passage? [A] 2 and 4 [C] Only 3 [B] 1 and 3 [D] Only 2


  10. Q.1 Consider the following statements regarding the plant species called creeping dogwood in the passage 1. It grows primarily in regions that were not sprayed with pesticide, and so served as a control for the experiment. species 3. It is similar to the red-osier dogwood, but its insect pollinators are known to be insensitive to the pesticide used in the study. 4. Its geographical range is similar to that of the red-osier dogwood, but the latter species relies less on seeds for reproduction. Which of the above statement(s) is/ are correct, as per the passage? [A] 2 and 4 IC] Only 3 [B] 1 and 3 [D] Only 2


  11. Q. 2 This question consists of an Assertion (A) and a Reason (R). Indicate your answer by selecting the correct alternative. Assertion (A): A wind-pollinated flowering tree that is short-lived would be most likely to experience a decrease in fecundity as a result of the spraying of a pesticide not directly toxic to plants. Reason (R): They are not dependent on a small number of insect-pollinator species [A] Both A and R are right and R is the correct explanation for A [B] Both A and R are right but R is not the correct explanation for A [C] A is right but R is wrong [D] A is wrong but R is right


  12. Q. 3 Consider the following statements regarding plant fecundity as it is defined in the passage 1. It is usually low if the plant relies on a small number of insect species for pollination. 2. It decreases as the percentage of unpalliated flowers on the plant increases. 3. It increases as the number of flowers produced by the plant increases. 4. It decreases as the number of flowers produced by the plant decreases Which of the above statements are correct, as per the passage? [A] 1, 3 and 4 IB] Only 2 [C] 2 and 4 [D] Only 1


  13. Q. 5 Consider the following statements regarding the forest regions in New Brunswick sprayed with most antibudworm pesticides other than Matacil 1. Many more plant species have become extinct in those regions than in the regions where Matacil is used. 2. The spruce budworm is under better control ii those regions than in the regions where Matatcil is sprayed. 3. The fecundity of some flowering plants in those regions may have decreased to an even greater degree than in the regions where Matacil is used. 4. The number of seeds produced by common plant species in those regions is probably comparable to the number produced where Matacil is sprayed. The passage suggests which of the statements as true? A] Only 2 [C] 2 and 4 [B] Only 3 [D] 2 and 3
