CBSE CLASS 10 SCIENCE SOLUTION PAPER (1)
1. Eucoelomates are multicellular animals that contain a body cavity or coelom formed from the mesoderm or gut and also called as animals with true body cavity. E.g., animals belonging to phylum Annelida. Pseudocoelomates are multicellular animals that contain a false fluid filled body cavity which is not formed from mesoderm or gut. E.g., animals belonging to phylum Aschelmenthes. 2. A generator is connected to the turbines, which rotates them to produce electrical energy based on electromagnetic induction in a power station. ENERGY SOURCE TO RUN TURBINE - TURBINE - GENERATOR - ELECTRICAL ENERGY SECTION – B 3.a) During the process of protein synthesis, the mRNA carries the codon, which is a sequence of three nucleotides of DNA. The tRNA carries the anticodon, which is the complimentary sequence to the particular triplet nucleotides of the DNA. b) Any shift in the position of the nucleotides of the genes causes minor or major genetic changes called mutation.
