Complete question:
A student is working on a lab where they are trying to identify an unknown substance. The student decides to smell the solution by taking a big breath over the test tube. They immediately start to cough and their lungs are burning.
Answer and Explanation:
Many chemicals might be recognized by their smell. Some of them might be inoffensive, some others might cause slight damage and some others might be very harmful to the person that inhales them.
In the exposed example, the solution probably damaged the respiratory tract, causing inflammation and irritation.
There are some issues to take into account to avoid an accident by inhaling a chemical:
<u>Precaution</u>:
- Study the security rules of the laboratory
- Always read the label of the substance
- Ask the teacher or the person in charge, about the correct procedure
- Proceed in the correct way, by driving the smelly vapors with your hand toward your nose. Never breathe directly over the test tube.
In case of accidents by inhaling you should:
<u>Response:</u>
- Take the affected person out of the laboratory
- Look for an airy place where the affected person might breath
- Call an emergency service
- Explain exactly what the affected person did and the chemicals that the person inhaled.
The cell membrane is composed by a lipidic bilayer. Phospholipids are most likely found in the membrane of a eukaryotic cell.
<h3>MEMBRANE COMPOSITION</h3>
The cell membrane is composed of
- glucans incrusted in between.
The membrane is mostly composed of phospholipids.
<h3>PHOSPHOLIPIDS</h3>
Phospholipids are amphipathic molecules.
They have hydrophilic heads facing the exterior and the interior of the cells and hydrophobic tails that arrange against each other in the interlayer space.
Lipids can easily change places with other lipids by lateral diffusion in the same layer.
They can diffuse transversally to the other layer but not as easily as lateral diffusion.
There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.
Phospholipids are most likely found in the membrane of a eukaryotic cell.
