The bacterial growth in liquid culture media can be observed as the increase in the __ a. Colony number b. Turbidity c. Color d. Temperature

14. The correct answer is b. Peptidoglycan. The bacterial cell wall is primarily composed of peptidoglycan, which provides structural support and shape to the cell.<br /><br />5. The correct answer is c. They play a role as a vector. Arthropods, such as insects and arachnids, are important in the transmission of infections because they can act as vectors, carrying and transmitting pathogens to other organisms.<br /><br />Which one is not a dimorphic fungi?<br />The correct answer is d. Aspergillus fumigatus. Aspergillus fumigatus is not a dimorphic fungus, while Blastomyces dermatitis, Coccidiodes immitis, and Histoplasma capsulatum are dimorphic fungi.<br /><br />Which one is the movement organel of bacteria?<br />The correct answer is a. Flagella. Flagella are the organelles responsible for movement in bacteria.<br /><br />18. The correct answer is b. Proteins. Proteins are added to bacterial culture media as a source of nitrogen, which is essential for bacterial growth and metabolism.<br /><br />19. The correct answer is c. Mesophilic. Human body temperature is optimum for the growth of mesophilic bacteria, which thrive at moderate temperatures.<br /><br />20. The correct answer is b. Turbidity. Bacterial growth in liquid culture media can be observed as an increase in turbidity, which indicates the presence of bacteria in the medium.
