*Assalamualaikum Dear* *members* ???? *10- June- 2023* *Today's paper* *Bt101* . *At 2:30 PM.* *Full paper shared.* ?????????? First *12 McQ* from *Salman file.* Subjective from handouts. 1. All organisms need *energy* to function. 2. First evolutionary scheme was proposed by jean Baptiste Lamarck in *1809* . 3.. One species gain benefit other species is harmed in parasitisam. 4. species that occur outside of their natural ranges because of human activity *Exotic* *Species* . 5. Rise in mean temperature of 0.6-1.0?C in arid coastal areas, arid mountains and hyper arid plains *Pakistan* . 6. Nitrogen fixing microbes requires enzyme *nitrogenase* 7. Near the surface of earth ozone concentration about *__0.04-0.15_ ppm* 8.The resemblance of one species to another for protective or aggressive purposes is *Mimicry* 9. The second major layer of Earth?s atmosphere is ( *Stratosphere* ) 11. Regions with identical climate have *different* floras and faunas ( *Buffon?s Law).* 12. Organic Compounds that contain Carbon atoms. 13. The atmospheric concentration of *CO2* measured from Antarctic ice core data implies that Earth?s climate has being pretty stable over the past 400,000 years. 14. Form of precipitation that is unusually acidic. *Acid rain* 15. *Secondary* *Treatment* is a Biological process. 16. Natural selection prefers *large* population. 17. Only change in *DNA* are transferred to next generations. 18. Winter Sleep Occurs in large animals for large *energy* reserves. 19. In preedation one animal kills and eats another animal one is *predator* and other is prey. 20. Intraspecific *competition* between members of same species for same resources. 21. Conventional aviation takes place in *troposphere*. 22. Decomposers absorb nutrients directly through chemical and biological processes without ingestion. 23. Productivity is the rate at which the organisms in the trophic level collectively synthesize new organic matter. 24. Rate of reproduction of common Carp is *300,000 / years.* 25. Land pollution *indirectly* affects the respiratory system of human beings. 26. Average Height of *troposphere* is *13 km* . 27. Which specie can survive beyond the carrying capacity A) r- selected species B) K- selected species C) N- selected species D) none. *Subjective* *Short questions.* 1. Population growth rate Definition. 2. Height of staratosphere at equator and pole. 3. Evidence of theory of natural selection *Long questions* 1. Write a note on troposphere 2. Types of autotrophs 3. Differentiate primary and secondary treatment of wastewater. *~Best regards*~ _Admin Zoology legends_ & Vu _biomedical group._ *Taaha khan* ??????
