Flagella c. The answer cannot be determined Which of the following pairs are mismatched? a Mitochondria- ATP production bLysosome-Digestive enzymes e Endoplasmic reticulum -internal transport d. Centrosome - food storage e Golgi complex-secretion 41- Which of the following chemical agents is used for sterilization? a. Ethylene oxide b. Soap c Chlorine d. Alcohol e. Phenolics 42 Which of the following pairs is mismatched? a. Bacteriostatic - Kills vegctative bacterial cells b Fungicide -Kills yeasts&molds; c. Germicide-kills microbes

Explanation / Answer

39) The green structures are the endospores.

40) Here the mismatch is centrosome with food storage. The function of centrosome is to organize microtubules and to pull the chromatids apart during cell division.

41) Ethylene oxide is the most commonly used gas treatment for sterilization since it has wide range compatibility.
