Aspirin is a weak acid with a Pka of 3.5. With this Pka of 3.5, it is in a neutral or what is known as protonated form at a pH below 2.5. At higher levels of pH, it becomes increasingly protonated or anionic, therefore, it is better absorbed in more acidic environment of the stomach. This is because absorption requires passage through the plasma membrane, the rate which is determined by the polarity of the molecule. Charged and highly polar molecules pass, slowly, while the neutral hydrophobic ones pass rapidly.
Answer:
Botulism is a rare, but life threatening infection caused by the bacteria Clostridium botulinum which spreads through contaminated food, soil, or through open wounds. Ingestion of bacterial spores and toxins are the main reasons behind the symptoms. Symptoms vary depending on the type of botulism.

Some energy sources are wind turbines, generation from air resistance
If my memory recalls correctly. Its because of the nature of phospholipids and their double membrane layer. It basically "keeps" all the water from escaping, due to the double bilayer
