Multicellular organisms arrange their cells into functional units. Which of the following examples? a. Tissues and organs Chloroplasts and Mitochondria Nucleic acids and amino acids Macromolecules and Proteins b. c. d.Explanation / Answer
27. c. Muscle cells
Explanation: Muscle cells require more energy for performing their work. Hence, more mitochondria are required in these cells.
28. c. CHO cells
Explanation: CHO or chinese hamster ovary cells are mammalian cells used for the producing recombinant proteins through tissue culture.
29. d. All of the above
Explanation: The differentiation of cells in a multicellular organism to perform specific functions is termed cell specialization.
30. d. monosaccharide
Explanation: Monosacchafidedes are simple sugers that cannot undergo further hydrolyzation.
