Question

Some nematode worms suck plant juices from the roots of plants and are economically important agricultural pests. Some fungi are usually decomposers of plant material, but some trap and kill nematodes at times. Arthrobotrys traps and kills nematodes, especially when they lack nitrogen sources. These two facts suggest that farmers could find Arthrobotrys an important tool in combating nematode infestations. Which of the following research questions would make a good starting point for developing such a defense against plant-sucking nematodes?A. What mechanisms do nematodes have that could allow them to escape from Arthrobotrys?B. Does nitrogen fertilization of crops affect the likelihood that ArthrobotrysC. What is the evolutionarily oldest method of trapping nematodes?D. Do nitrogen-fixing bacteria provide nitrogen to the fungi?

Answer 1

Answer:

A. What mechanisms do nematodes have that could allow them to escape from Arthrobotrys?

Explanation:

Since the research question has to do with likely defense mechanisms of nematodes against the traps and death from Arthrobotrys, option A seems like the most plausible option out of all the options.

Option B seems incomplete while C and D have no direct relation with defense mechanism of nematodes against Arthrobotrys.
