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]
Sorry idk because they’re only 5 to 10 answers and i know nothing just finishing my set up
<span> They are unable to pass through the plasma membrane and have different methods of action. They attach to their receptors in the target cell surface and influence activity within the cell through cytoplasmic intermediates called second messengers. </span>
<span>The two most important messengers are cAMP and inositol triphosphate. </span>
<span>Cyclic AMP: ATP is converted into cAMP after a series of reactions on the plasma membrane following the attachment of the hormone to the membrane. cAMP relays the signal from the membrane to the metabolic machinery of the cytoplasm. </span>
<span>Inositol Triphosphate: Involves the use of Ca+2 that regulates cellular protein activity.

Hope this helps !!!^_~!!!
Answer:
Chromosomal non‐non disjunction resulting in extra sets of genes
1. b - plants make their own food (glucose)
2. 1 - fish and upwards have a jaw (there are fish that do not have jaws, but this is likely where the divergence happens - before 1 is likely jawless fish.
3. b - cellular respiration
4. They belong to the same kingdom (Animalia) but different phyla (dogs are in the phylum Chordata - insects are not)
