Answer:
See the explanation of canities subita below
Explanation:
Marie Antoinette's experience is now termed as Marie Antoinette syndrome.
There is an occurrence of Marie Antoinette syndrome when a huge shock or life-threatening situation result in people losing the color of their hair.
But the stories behind Marie Antoinette syndrome is regraded as a historical fiction. The reason is that canities subita is the only condition that can make hair to turn to white. Canities subita explains that the hair can only turn white gradually but not overnight.
Therefore, MOST likely explanation that may make hair to seem that it has turned white overnight under canities subita is when there are already strands of different colors like white, grey and black; and there is a sudden massive fall out of the black and grey hair, the white-colored hair will be the only ones that will remain. This will give the impression that the hair has changed to black overnight.

Answer:
A. epinephrine
Explanation:
Bronchial constriction usually involves the tightening of the smooth muscles which surrounds the tube-like bronchial airways. This occurs via extra mucus production, spasming of smooth muscles, or swelling/inflammation of layers within bronchi or bronchioles. Bronchial constriction typically results in symptoms of wheezing, coughing and shortness of breath.
This can be treated via the use of the hormone epinephrine, a bronchiodilator. For some cases like asthma, epinephrine in small aerosolized (inhaled) doses can lead to the <em>temporary</em> relief of symptoms. Epinephrine acts by making bronchial tubes wider to allow the passage of air.
In the body, smooth muscle cells in the veins, arteries and heart are under the control of epinephrine receptors called β2 receptors. Epinephrine binding to the receptor triggers a cell signalling cascade that activates β2 receptors to dilate smooth muscle in the lungs.
Here's how-
- Calcium is essential to mediating muscle cell signalling and thus contraction
- in the lungs, epinepherine-β2 receptor binding leads to enzyme activation (adenylyl cyclase)
- conversion of the energy molecule ATP to the secondary messenger molecule cyclic AMP.
- cAMP inhibits the activity of the enzyme <em>myosin light chain kinase </em>(MLCK) in smooth muscle
- ∴ the enzyme remains inactive and the muscles relax
<em>Summary:</em><em> epinephrine → muscle relaxation →</em><em> bronchial dilation (reduced diameter) </em><em>→ decreased respiratory distress → easier breathing.</em>
