Question

• A. Adhesion
• B. Colouring pigment
• C. Locomotion
• D. Both A and C
  

Answer 1

Answer: (A), (B)

The correct options are
A Adhesion
B Colouring pigment

Adhesins are cell surface components or appendages of bacteria that facilitate adhesion or adherence to other cells or to surfaces. Adhesins are a type of virulence factor. Adhesins are expressed by both pathogenic bacteria and saprophytic bacteria. This prevalence marks them as key microbial virulence factors in addition to a bacterium's ability to produce toxins and resist the immune defenses of the host.

So, the correct answer is 'Adhesion and Colouring pigment'.
