Answer: I would talk with them and tell them that alcohol in moderation is completely fine. So long as they are the legal drinking age. And that their first time to drink it I'd like for them to do it with me so we can tell what negative effects it will have on them. That and we'd know their tolerance for it.
The odorant molecules arrive either directly by diffusion into the mucus, or are supported by transport proteins (odor binding protein or OBP) that allow the hydrophobic molecules - majority - to penetrate the mucus covering the epithelium, and thus to reach the membrane receptors present on the eyelashes of the olfactory neurons. These transport proteins are thought to concentrate odorant molecules on membrane receptors. As ligands, the odorant molecules bind to membrane receptors on the eyelashes, triggering a transduction pathway for a stimulus involving G.olf protein (first messenger), adenylate cyclase, and cAMP ( second messenger). The second messenger causes the opening of ion channels Ca2 + / Na + present on the plasma membrane of the olfactory receptor, these two ions then enter the cell. Ca2 + causes the opening of a Cl- channel, the output of this ion causes depolarization of the membrane so that the olfactory receptor produces action potentials. These impulses will go directly to the olfactory bulb, in the prefrontal region of the brain, where this information (and that of taste) is processed by the body.
Answer:
to swim at a vigorous pace for one hour by the end of two months
Explanation:
'C' and 'D' cant possibly be right cause the goal is to swim for longer not shorter. 'A' can't be right cause you cant possibly learn to swim faster from 30 minutes to an hour in only a week, that just sounds impossible.
im totally guessing here, but i think 'B' is right.
