Final answer:
The F1 capsule is expressed in aerobic conditions and not expressed in d) anaerobic conditions.
Step-by-step explanation:
The F1 capsule is expressed in aerobic conditions and not expressed in d) anaerobic conditions.
Aerobic conditions refer to environments with an adequate supply of oxygen. In these conditions, bacteria can generate energy through aerobic respiration, which requires oxygen. Aerobes are organisms that require oxygen to survive, and they express the F1 capsule.
On the other hand, anaerobic conditions are characterized by the absence or limited supply of oxygen. Anaerobic respiration occurs in these conditions, and anaerobes are organisms that can survive and grow without oxygen. In anaerobic conditions, the F1 capsule is not expressed.
