Bdellovibrio Species are ________ Cells That Replicate in the ________

Question

Bdellovibrio species are ________ cells that replicate in the ________.
A) symbiotic / gills of clams
B) lithotrophic / deep subsurface
C) predatory / periplasmic space
D) denitrifying / sediments of freshwater lakes

Accepted Answer

Bdellovibrio species are predatory bacteria that replicate in the periplasmic space of other bacteria. They use flagella to locate and penetrate their host, then digest the host's contents to replicate themselves. They are not symbiotic, lithotrophic, or denitrifying, so options A, B, and D are incorrect.
