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?
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.
-Hypercapnia is a condition of abnormally elevated carbon dioxide (CO2) levels in the blood. Carbon dioxide is a gaseous product of the body's metabolism and is normally expelled through the lungs.
The condition usually happens as a result of hypoventilation, or not being able to breathe properly and get oxygen into the lungs.
The combination of acetyl CoA and oxaloacetate drives the formation of nicotinamide adenine dinucleotide + hydrogen (NADH). Poisoning the enzyme that aids this combination will result to lesser production of NADH which would lead to weakening the proton gradient and the reduction in the amount of adenosine triphosphate (ATP) produced.
In genetics, an operon is a functioning unit of DNA containing a cluster of genes under the control of a single promoter. ... Operons are also found in viruses such as bacteriophages.
