PREFACE“Don’t follow your dreams; chase them!”- a quote by Richard Dumbrill is perhaps the most pertinent forone who is aiming to crack entrance examinations held after std. XII. We are aware of an aggressivecompetition a student appearing for such career-defining examinations experiences and hence wanted tocreate books that develop the necessary knowledge, tools and skills required to excel in theseexaminations.ontentFor the syllabus of MHT-CET 2021, 80% of the weightage is given to the syllabus for XII standard whileonly 20% is given to the syllabus for XI standard (with inclusion of only selected topics).Although the syllabus for Std. XI - XII and MHT-CET is aligned, the outlook to study the subject shouldbe altered based on the nature of the examination. To score in MHT-CET, a student has to be not just goodwith the concepts but also quick to complete the test successfully. Such ingenuity can be developedthrough sincere learning and dedicated practice.Having thorough knowledge of theory and its applications is a prerequisite for solving MCQs of Biology.Students must know the important processes and mechanisms that formulate the basics of the chapter.Biology is conveyed using diagrams and figures; therefore, students should study and understand themwell. Students should aim to study integrated concepts and relate them to their real – life applications inorder to visualize a clear map of the entire concept. It should be kept in mind that every single line of texthas potential of generating several MCQs.CAs a first step to master MCQ solving, students should start with elementary questions. Once a momentumis gained, complex MCQs with higher level of difficulty should be practised. Relevant questions fromprevious years as well as from other similar competitive exams should be solved to obtain an insight aboutplausible questions.Competitive exams challenge the understanding of students about subject by combining concepts fromdifferent chapters in a single question. To figure these questions out, cognitive understanding of thesubject is required. Therefore, students should put in extra effort to practise such questions.eSuch a holistic preparation is the key to succeed in the examination!To quote Dr. A.P.J. Abdul Kalam, “If you want to shine like a sun, first burn like a sun.”plOur Triumph Biology book has been designed to achieve the above objectives. Commencing from basicMCQs the book proceeds to develop competence to solve complex MCQs. It offers ample practice ofrecent questions from various competitive examinations. While offering standard solutions in the form ofconcise hints. Each chapter ends with an Evaluation test to allow self-assessment.mFeatures of the book presented on the next page will explicate more about the same!We hope the book benefits the learner as we have envisioned.SaThe journey to create a complete book is strewn with triumphs, failures and near misses. If you thinkwe’ve nearly missed something or want to applaud us for our triumphs, we’d love to hear from you.Please write to us on: mail@targetpublications.orgFrom,PublisherEdition: FirstBest of luck to all the aspirants!

MHT-CET Triumph Biology (MCQs)GLOBAL WARMING Greenhouse Effect and Global Warming Greenhouse effect is the heating-up of the earth’s ontentatmosphere due to trapped infra-red rays reflectedfrom the earth’s surface by atmospheric gases. Gases responsible for global warming CO2, N2O,CH4, CFCs. Global warming results in hotter summers,desertification, change in rainfall pattern, flooding,melting of polar ice-caps and glaciers. Control measures to check global warming includegrowing more trees, minimizing use of fossil fuels, useof organic manure and biofertilizers, and developingsubstitutes for CFCs.Ozone DepletionOzone layer acts as a protective shield for life on theearth from the harmful UV rays of the sun.A large area of thin ozone layer is formed in theAntarctica region which is commonly called Ozonehole.Chlorofluorocarbons (CFCs) are mainly responsiblefor the depletion of ozone layer.Depletion of ozone layer results in damage to skincells, skin cancer, cataract, permanent damage tocornea and snow blindness. Deforestation Deforestation is the permanent removal, decrease ordeterioration of forests and woodlands. It results in loss of biodiversity, reduced soil fertility,soil erosion, global warming, global climatic changesand increased accidents of landslides.15.1 Levels of Biodiversity15.0 IntroductioneBiodiversity includes(A) microorganisms, plants, algae, fungi andanimals(B) only microorganisms, algae and fungi(C) only plants and animals(D) only animalsDiversity is with respect to(A) colour, form, size and shape of organismsonly(B) mode of nutrition and type of habitat only(C) reproductive cycle, duration of life span,type of habitat only(D) size, shape, colour, form, mode ofnutrition, type of habitat, reproduction,motility, duration of life span, etc.m2.Part of nature which includes the differences inthe genes among the individuals of species, thevariety and richness of all plants and animalspecies at different scales in a space and thetypes of ecosystem within a defined area iscalled(A) ecology(B) biodiversity(C) habitat(D) nicheSa3.4.384Which of the following is/ are a level(s) ofbiodiversity?(A) genetic diversity(B) species diversity(C) ecosystem diversity(D) all of these6.Complete the analogy.Intraspecific diversity: GeneticInterspecific diversity:(A) Species diversity(B) Ecosystem diversity(C) Ecological diversity(D) Allelic diversitypl1.5.CClassical ThinkingThe term biodiversity was coined by(A) Walter Rosen(B) Gregor Mendel(C) Oparin and Haldane(D) Huxleydiversity::7.The number of species of plants and animalsthat are present in a region, constitutes its(A) species diversity(B) community diversity(C) interspecific diversity(D) all of these8.Variety of species is known as species(A) richness(B) evenness(C) unevenness(D) both (A) and (B)9.Species diversity deals with(A) species richness(B) species evenness(C) intraspecific diversity(D) both (A) and (B)
