Many discoveries in science have been accidental. This is true for plant hormones also. Can you justify this statement by giving an example? Also, what term is used for such accidental findings?

State whether the following statements are true or false. Correct the false statements: Antibiotics useful to one person can be suggested to others also.

You have heard about several insectivorous plants that feed on insects. Nepenthes or the pitcher plant is one-such example, which usually grows in shallow water or in marsh lands. What part of the plant is modified into-a 'pitcher'? How does this modification’help.the plant for food even though it can, photosynthesize like any Other green plant?

The coutries which do not have oil reservatirs in their land import oil from other countries. But sometimes during transporting oil through sea routes, accidental oil spilling occurs. This oil spilled in the ocean may prove fatal and toxic to aquatic animals. Therefore, removel of this spilled oil is essential for protection of aquatic life. For removing this oil layer, certain microbes like Pseudomonas spp. and Alcanivarax borkumensis are used. These microbes have the ability to destroy the pyridines and other toxic chemicals. The hydrocarbonoclastic bacteria (HCB) are able to decompose the hydrocarbons and bring about the reaction carbon with oxygen resulting in formation of CO_(2) and water. Like oil spills cause damage to aquatic life, platic forms the major part of the grabage on land. Plastics are difficult to degrade as they are made up of PET. By research, various species like Vibrio and Idenoella sakaiensis which can degred PET.By research, various species like Vibrio and Ideonella sakaiensis which can degrade PET have been identified. There are cartain species of microbes which can decompose rubber from garbage. Based on the given paragraph answer the following question. Name any two species of microbes which can degrade rubber from

Read the paragraph and answer the questions given below: Renewable energy is energy produced from sources that do not deplete or can be replensied within a human's life time. The most common examples include wind, solar, geothermal, biomass, and hydroelectric power. This is in contrast to non-renewable energy is derived directly or indirectly from the sun. Sunlight can be captured directly using solar technologies. The sun's heat drives winds, whose energy is captured with turbines. Plants also rely on the sun to grow and their stored energy can be utilized for bioenergy. Not all renewable energy sources rely on the sun. For examples, geothermal energy utilizes the Earth's internal heat, tidal energy relies on the gravitational pull of the moon, and hydroelectric power relies on the flow of water. Give the examples of renewable energy.
