The max amount of fiber for women 19 - 50 is 25 grams daily.
Answer:
Clothes are one of the fundamental necessities of human beings like food and shelter to protect themself from cold, rain, and other environmental conditions. Clothes nowadays become a status symbol and form of expression.
Clothes should not be a subject of ethics as it is their personal choice and clothes also use as a form of art. One should not defy or judge a person by his or her clothes as it a personal choice and environmental necessities.
However, in some cases like school, workplace, there are obligations to follow the dress code, it is a form of ethics but it is to show professionalism and equality among all students and employees.
<span>The answer is extracapsular cataract extraction (ECCE). It is
a kind of eye surgery in which the lens of the eyes are removed, leaving the
elastic capsule covering the lens which is left partially attached to let the
implantation of an intraocular lens (IOL). This approach is compared with
intracapsular cataract extraction (ICCE), an older procedure in which the
surgeon detached the complete lens within its capsule and left the eye aphakic
(without a lens). The patient's vision was corrected after intracapsular
extraction by extremely thick eyeglasses or by contact lenses. There are two
major types of ECCE: manual expression, in which the lens is removed through a slit
made in the cornea or the sclera of the eye; and phacoemulsification, in which
the lens is shattered into fragments inside the capsule by ultrasound energy
and removed by aspiration.</span>
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>
