Is he taking any drugs for sexual enhancement or erectile dysfunction!?!?
Nitroglycerin is a vasodilator, which means that it relaxes and dilates (widens) blood vessels; this is a positive effect for coronary arteries, whose narrowing and/or occlusion (blockage) may be the cause of [cardiac] chest pain.
But, other vessels throughout the body also dilate, which can be good in hypertension.
However, a specific class of drugs known as phosphodiesterase-5 inhibitors (PDE-5-I), which includes sex-enhancing drugs for erectile dysfunction (ED), will irreversibly keep body vessels dilated when nitroglycerin is also present in the bloodstream. This can lead to a life-threatening pooling of blood of the arms and legs (extremities) and lower body, keeping adequate blood from reaching the heart, lungs, and brain. This emergency is known as vasogenic shock!
Examples of PDE-5 inhibitors are Viagra, Levitra, and Cialis. [generic names of this class are: vardenafil, sildenafil, tadalafil and avanafil]
Interesting question.
"They are prokaryotes" - YES, both bacteria and Archaea are considered prokaryotes
"They reproduce by binary fission" - YES, but keep in mind (in case your teacher drops this on you in a quiz or exam) that Archaea do not form spores, which many bacteria are capable of
"They are believed to be the ancestors of plants" - ?? Not sure. If I had to guess, I would go with NO, since the general consensus is that plants developed from green algae. Check your class notes.
"They have a cell membrane made of unusual lipids" - NO, only Archaea have that (they possess unusual ether lipids as part of their cell membranes, which bacteria do not)
Hope this helps!
Good luck.
