Q.4917·Miscellaneous·2021·EasyApproximately 80 percent of all flowering plant species are pollinated by animals, including birds and mammals, but the main pollinators are insects. Pollination is responsible for providing us with a wide variety of food, as well as many plant-derived medicines. At least one-third of the world’s agricultural crops depend upon pollination. Bees are the most dominant taxa when it comes to pollination and they are crucial to more than four hundred crops. Pollination is an essential service that is the result of intricate relationship between plants and animals, and the reduction or less of either affects the survival of both. Effective pollination requires resources, such as refuges of pristine natural vegetation. On the basis of the passage given above, the following assumptions have been made: 1. Sustainable production of India’s cereal food grains is impossible without the diversity of pollinating animals. 2. Monoculture of horticultural crops hampers the survival of insects. 3. Pollinators become scarce in cultivated areas devoid of natural vegetation. 4. Diversity in insects induces diversity of plants. Which of the above assumptions is/are valid?View question

Q.4920·Miscellaneous·2021·EasyA biology class at high school predicted that a local population of animals will double in size every 12 years. The population at the beginning of the year 2021 was estimated to be 50 animals.

Q.4923·Miscellaneous·2021·EasyResearchers simulated street lighting on artificial grassland plots containing pea-aphids, sap-sucking insects, at night. These were exposed to two different types of light – a white light similar to newer commercial LED lights and an amber light similar to sodium street lamps. The low intensity amber light was shown to inhibit, rather than induce, flowering in a wild plant of the pea family which is a source of food for the pea-aphids in grasslands. The number of aphids was also significantly suppressed under the light treatment due to the limited amount of food available. Which one of the following statements best reflects the most critical inference that can be made from the passage given above?View question
Q.4924·Miscellaneous·2021·EasyResearchers were able to use stem cells to gauge the neurotoxic effects of the environmental pollutant Bisphenol A (BPA). They used a combination of biochemical and cell-based assays to examines the gene expression profile during the differentiation of mouse embryonic stem cells upon treatment with BPA, a compound known to cause heart diseases, diabetes, and developmental abnormalities in humans. They were able to detect and measure BPA toxicity towards the proper specification of primary germ layers, such as endoderm and ectoderm, and the establishment of neural progenitor cells. On the basis of the passage given above, the following assumptions have been made: 1. BPA may alter embryonic development in vivo. 2. Biochemical and cell-based assays are useful in finding out treatments for pollution-induced diseases. 3. Embryonic stem cells could serve as a model to evaluate the physiological effects of environmental pollutants. Which of the above assumptions are valid?View question

Q.4929·Miscellaneous·2021·EasyA boy plays with a ball, and he drops it from a height of 1.5 m. Every time the ball hits the ground, it bounces back to attain a height 4/5th of the previous height. The ball does not bounce further if the previous height is less than 50 cm. What is the number of times the ball hits the ground before the ball stops bouncing?View question
Q.4930·Miscellaneous·2021·EasyA study conducted on the impacts of climate change over the Cauvery basin of Tamil Nadu using regional climate models showed an increasing trend for maximum and minimum temperatures, and a decrease in the number of rainy days. These climatic shifts will have an impact on the hydrological cycles in the region, lead to more run-off and less recharge, and affect the groundwater tables. Further, there has been an increase in the frequency of droughts in the State. This has driven farmers to increase dependency on groundwater resources to secure their crops. Which one of the following statements best reflects the crux of the passage given above?View question
Q.4931·Miscellaneous·2021·EasyComputers increasingly deal not just with abstract data like credit card details and databases, but also with the real world of physical objects and vulnerable human bodies. A modern car is a computer on wheels; an aeroplane is a computer on wings. The arrival of the “Internet of Things” will see computers baked into everything from road signs and MRI scanners to prosthetics and insulin pumps. There is little evidence that these gadgets will be any more trustworthy than their desktop counterparts. Hackers have already proved that they can take remote control of internet connected cars and pacemakers.
