what is the role of flagella?
○ to help bacteria grow
○ to help bacteria move
○ to help bacteria reproduce
○ to detect when bacteria are present
question 6 0.5 pts
bacteria cells can be shaped like
○ rods
○ spirals
○ spheres
○ all of the above

Explanation:

First Question (Role of flagella):

Flagella are whip - like structures in bacteria. Their main function is to provide motility, which means they help bacteria move. Growth of bacteria is related to processes like cell division and nutrient uptake, not flagella. Reproduction in bacteria (like binary fission) doesn't involve flagella. And flagella don't have a role in detecting the presence of bacteria. So the correct option is the one that says "to help bacteria move".

Bacterial cells can have different shapes. Rod - shaped (bacilli), spherical (cocci), and spiral - shaped (spirilla) are common bacterial cell shapes. So bacteria cells can be shaped like rods, spirals, and spheres, which means the correct option is "all of the above".

Answer:

The option (the one with the text "to help bacteria move")
