Because they provide new insights in the research for biotechnology and other useful resources to the knowledge of biology.
<span>Transgenic means that one or more DNA sequences from another species has been introduced by artificial means. For example, animals usually are made transgenic by having a small sequence of DNA injected into a fertilized egg or developing  embryo. Transgenic plants can be made by introducing foreign DNA into a variety of different tissues.</span>

Answer:
Major cell parts function just like the structures and people who work together in a factory. Cells have strong cell walls and a cytoskeleton to keep their shape; the walls are made of fiber for protection just like a factory building has sturdy walls for support.

Answer: 30. D. Cell
31. A. Tissue
32. D. Biome
33. A. Population 
34. D. Condensation
35. B. Precipitation
Explanation:
30. A cell is a largest component of life among the options given. As it includes within it molecule, and organelles required for the functioning and metabolism of cell.
31. A tissue is the smallest component of life. It is made up of group of cells. The cells combine together in tissue to perform a specialized function in organisms. 
32. Biome is the largest ecological group which includes diversity of living organisms interacting with the physical environment. The biome is characterised by abiotic factors like climate, temperature, geography, and soil and also by the biotic factors such as flora and fauna. 
33. Population is the smallest group which includes the members belonging to the same species living in the same location or region. These members are capable of inbreeding among themselves and producing viable offsprings.
34. Condensation is a process in which the water vapors being in high temperature cools down in the sky to form clouds. It is the part of water cycle. 
35. Precipitation is the part of the water cycle. In this the clouds formed after the condensation process, due to increase in amount of water vapors in them the water falls off under the effect of gravity. The precipitation is in the form of sleet, snow, hail, drizzle and rain.
