Answer:
The statement that is true about leukotrienes is that they create excess mucus in the airways (last option).
Explanation:
Leukotrienes are inflammatory mediators, derived from arachidonic acid, in whose presence occurs increased vascular permeability in tissues, leading to inflammatory processes.
The presence of leukotrienes has been related to the development of allergic reactions, mainly in the respiratory tract, producing edema in the mucosa, contraction of the smooth muscles of the airways and increased production of mucus
in the airways.
the other options are not correct because leukotrienes:
- <em>Produce contraction of the smooth musculature around the airway.
</em>
- <em>Are related to the production of bronchial asthma.
</em>
- <em>Are inflammatory (chemical) mediators. </em>
Answer:
All I can really say is to use your best judgement. I mean it's oki to b curious and want to know what your crush looks like, but it's a little suspicious if he wouldn't just give you a picture of himself, instead of you having to go to the school website (although I don't know if he has or hasn't). And no, It's not bad, because you didn't really turn him and his brother against each other. You didn't feel the same way and that's how you feel, no shame in that luv. Lol and I don't know about your picture being in his wallet, that's a little creepy, not gonna lie.
Explanation: Hope this helps in some way ^-^.
It depends on which drug is to be given and what is its mechanism of action. e.g. for any antibiotic intra venous route will be a suitable choice whereas in case of a laxative we can administer it rectally if oral is not tolerated.
