The property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules. The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.
<span>The basic building blocks of a cell membrane are phospholipids. Phospholipids contain a hydrophobic (insoluble in water) end made up of two fatty acid chains of nonpolar molecules such as carbons and hydrogens. The other end is hydrophobic (soluble in water) and contains polar phosphate molecules. These phospholipids are arranged in a bilayer with their hydrophilic end group exposed to water on each side of the membrane and the hydrophobic nonpolar molecules protected inside the double layer. </span>
Answer:
Metabolism
Explanation:
Metabolism is a chemical process occurring within a living organism in order to maintain life.
Drug metabolism involves the breakdown of drugs by specialized enzymatic system. This metabolism is important in pharmacokinetics since it determines the duration and intensity of a drug.
In humans, it takes place in the liver and enzyme cytochrome P-450 (CYP450) helps in the breakdown of the drugs.
There for immature liver and low levels of this enzyme will affect the aspect of metabolism
THe 3 sources of genetic variation are the following
- mutation - the changing of DNA Structure
- Lateral gene transfer - the movement of genetic material into unicellar genes.
- <span>genetic recombination during sexual reproduction</span>
