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]
Answer:
Birds have remarkably specialized bones that are pneumatic, because they are full of air sacs that provide a continuous flow of breath throughout their bodies. In short, their lungs are essentially hooked up to their bones.

Explanation:
A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Answer:Answer: Since certain bases always appear in pairs, they will have equal percentages of the DNA composition. The percentage of adenine will equal the percentage of thymine, and the percentage of cytosine will equal the percentage of guanine. Together, these percentages will add to 100%
