Question

64. is/are bacterial flagellar arrangements that are polar A. monotrichous B. amphitrichous C. lophotrichous D. peritrichous E. A, B, and c 65. The two commonly used methods to determine if a bacterium is motile are wet-mount preparation (microscopic) and motility media (mac-roscopic) A. TRUE B. FALSE 66. Brownian motion is the ordered moving of particles resulting from their collisions with atoms or molecules in the water.

Answer 1

Question

64. The monotrichous , amphitrichous and lophotrichous flagella arrangement are polar. Hence, option E is correct.

65. This is true statement as wet-mount preparation and motility media are used.

66. This is false statement as Brownian movement are not ordered movement and they are random movement.
