Question
A. Photorhabdus luminescens is perhaps the most unusual microbe yet proposed to be used as a bioinsecticide. Photorhabdus luminescens and the microscopic worm Heterohabditis bacteriophora are (bacteria, symbionts, nematode worms, or wax worms) The P. luminescens (nematode worms, wax worms, or bacterium) lives in a (nematode worm, wax worm, or bacteria) host. This host then parasitizes an insect larva, and the (wax worm, nematode worm, or bacteria) within it produce (toxins, bacteria, or spores) that kill the (nematode worm, wax worm, or bacteria).
B. The relationship exhibited by P. luminescens bacteria and the nematode worm Heterorhabditis bacteriophora is a good example of ________. (commensalism, parasitism, or mutalism)
Explanation / Answer
ANSWER:
A. Photorhabdus luminescens is perhaps the most unusual microbe yet proposed to be used as a bioinsecticide. Photorhabdus luminescens and the microscopic worm Heterohabditis bacteriophora are nematode worms The P. luminescens bacterium lives in a nematode worm host. This host then parasitizes an insect larva, and the nematode worm within it produce bacteria that kill the nematode worm.
B. The relationship exhibited by P. luminescens bacteria and the nematode worm Heterorhabditis bacteriophora is a good example of parasitism.
