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.
The answer is organic farming.
Answer:
Let me know if this is right Answer: Nucleus
Explanation:
This organelle known as the Nucleus has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.
<span>Eukaryotic Can't be multicellular because it's one cell, heterotrophic are organisms that feed on other organisms to get energy, and prokaryotes don't have membrane-bounded organelles</span>
