There are benefits for doing virtual school. For example, students are able to have a more flexible schedule. Instead of having to spend all morning getting ready and travelling to their school, they can instead sleep more, or use that extra time to catch up on work. Passing periods can be used to actually tend to the students need, instead of focusing on getting to the next class. Of course, another benefit of virtual school is safety due to the ongoing pandemic.
Of course, there are disadvantages when it comes to virtual schooling as well. Students are typically sitting down for their classes, and if they're confined to their chairs for however long the school hours may be, it could be really unhealthy. Students may also be distracted, as they are in their own home. They can get sidetracked and procrastinate, making them not listen to the lessons at all. Some may abuse the system and skip out on assignments as well.
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.
