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.
<span>The answer to this question would be DNA. Protein and nucleic acids also not giving much energy.
The organic compound is included carbohydrate, lipids, proteins, nucleic acid, and DNA. From that list, carbohydrate is the primary source of energy. Lipid is used to store energy as it giving highest energy per gram. </span>
Answer:
Stabilizing selection is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value.
directional selection is a mode of natural selection is an extreme phenotype is favored over other phenotypes.
Disruptive selection describes changes in population genetics in which extreme values for a trait are favored over intermediate values.

Answer and Explanation:
Certain foods that are incomplete proteins do not contain all of the necessary amino acids that would be helpful.
Incomplete protein foods are anywhere from seeds, nuts, and whole grains. Whole grains consist of whole wheat bread and brown rice. Not only that, but even types of beans, peas and lentils (which tend to be part of the legume family).
Typically, incomplete proteins are harder for the body to digest and brake down. But don't be fooled, not all complete proteins are easy to be broken down either.
