Answer
<p> <br /><br />13. b. <br />During germination, the first part of a seedling to emerge from the seed is typically the root.<br /><br />14. b. <br />Fruits' primary function is to assist in seed dispersal.<br /><br />15. a. <br />Fruits are formed from a flower's ovary after pollination and by fertilization of the egg in the flower's ovary.<br /><br />16. b. <br />Sexual reproduction in flowering plants requires pollens for fertilization.<br /><br />17. c. <br />Annelids such as earthworms can reproduce by regenerating parts, a process known as "fragmentation".<br /><br />18. b.<br />The reproductive process wherein females lay eggs (usually in water bodies) that are later fertilized by males is known as "external fertilization".<br /><br />19. b.<br />Changes in the DNA of an organism potentially leading to changes in its traits, and could lead to formation of genetically modified organisms particularly refers to the techniques applied in Genetic Engineering.<br /><br />20. d. <br />The processes involved in the central dogma of molecular biology, which explains protein synthesis are: Replication, transcription, and translation in that specific sequence--- DNA replicates, converts to RNA (via transcription), this RNA then codes for proteins (via translation).<br /><br />21. d. <br />Gene expression occurs through DNA transcription- where a particular segment of DNA is copied into RNA.<br /><br />22. d.<br />Pharming is a biotechnological method that manipulates organisms (usually microbes or animals) to produce pharmaceutical products - so largest application is production of substances used as drugs.<br /><br />23. b. <br />Genetic engineering may significantly increase crop yield, one of its greatest potential applications in agriculture.<br /><br />24. d.<br />Restriction Enzymes, also known as restriction endonucleases, serve as molecular 'scissors' that can cut DNA at specific base sequences.<br /><br />25. d.<br />While gene contamination from existing plant varieties is a concern in applying GMO techniques, it is not a major concern related to the "use" of a genetically modified crop per se, after having elected to cultivate GM crops, the concern is primarily physiological/ health & ecological impact.<br /><br />26. c.<br />Carbon dioxide is a byproduct of organismal respiration.<br /><br />27. g.<br />Catabolism refer to biochemical reactions that break down larger organic molecules to generate energy ('Metabolic hydrolysis').<br /><br />28. i.<br />The cardiovascular system distributes oxygen and nutrients throughout the body.<br /><br />29. j.<br />The process of digestion involves turning food items into soluble substances enabling absorption by body .<br /><br />30. h.<br />Endocrine glands play crucial role in hormone (chemical messengers) regulation and metabolic processes in organismal bodies.<br /><br />31. d.<br />The primary function of excretion is to remove metabolic waste from the body <br /><br />32. e.<br />Glucose levels are primarily controlled by the pancreas, through insulin and glucagon.<br /><br />33. f.<br />Homeostasis is equated to maintenance of stable internal environment in an organism.<br /><br />34. a.<br />The immune system is instrumental in defending the body against establish_ in particular ,pathogen attacks.<br /><br />35. b.<br />The nervous system controls function of the most organ systems and responses to environmental cues.</p>
