Questions based on paragraph The important parts of computer include the Input unit, the Central Processing Unit (CPU) or the processor and the Output unit. The Input unit is used to enter information or data into the computer. Some of the devices used for input include the keyboard and the scanner. On the other hand, the Output device is used for Providing the result / solution / answer to the user. Generally a monitor or printer is used as an output unit. The Processing unit consists of a memory unit, control unit and ALU i.e. arithmetic logic unit. The Processing unit receives the input in form of instructions, executes each instruction in a specific order and provides the output to the user. What is the main function of the Processing unit? What are its important parts?

Paragraph based Questions : Read the paragraph and answer the questions given below : Remediation is the process of removing dangerous or poisonous substances from the environment, or limiting the effect that they have on it. When any biological organism is used for remediation, it is called bioremediation. When plant species are used for the purpose of remediation, it is called phytoremediation. When any microbes are used then it is named as microbial remediation. The methods of such remediation have helped to clean the environment from toxic effluents, especially sewage and crude oi]. Dr. Anand Chakraborty, a scientist of Indian origin, has worked on Pseudomonas aeruginosa which have reduced the crude oil films into carbon dioxide and water. Which environmental pollutant is mainly removed through bioremediation processes?

Paragraph based Questions : Read the paragraph and answer the, questions given below: Sulphuric acid is present in the acid rain and materials coming out of mines . You know that erosion of metals present in statues, bridges and buildings occurs due to it. Sulphuric acid is a source of energy for some species of bacteria like Acidophilum spp. and Acidobacillus ferrooxidans Hence. these bacteria can control the soil pollution occurring due to acid rain water soluble salts of uranium are present in the wastes produced during electroplating and in effluent released in the environment from the atomic energy Plant. Geobacter convert these salts of uranium into insoluble salts and thereby prevent those salts from mixing with groundwater sources. What are the water soluble salts in nuclear power plants and in the process of electroplating?

Read the paragraph and answer the questions given below : Reproduction is the process by which the living Species continues its existence. Lower organisms carry out asexual reproduction while higher plants and animals always show sexual reproduction. Plants reproduce asexually by methods such as fragmentation, vegetative propagation, budding, Spore formation. For sexual reproduction they form gametes. In animal kingdom, budding, fission of different types and parthenogenesis are some of the methods that do not require both the sexes. Though regeneration also forms new individual, it is not considered to be a reproductive process because. basically it is a repair process. The ability to regenerate is lost in higher phyla. In human beings it is restricted only to wound healing. Sexual reproduction is also undergoing lots of experimentation such as cloning which may make females capable of producing their own baby without intervention of any male. Answer the follolwing question. What are methods of reproduction in plants?
