First-pass effect.
The first-pass effect involves drugs that are given PO and absorbed from the small intestine directly into the portal venous system, which delivers the drug molecules to the liver. Once in the liver, enzymes break the drug into metabolites; they may become active or may be deactivated and readily excreted from the body. A large percentage of the oral dose is usually destroyed and never reaches tissues. Oral dosages account for this phenomenon to ensure an appropriate amount of the drug in the body to produce a therapeutic action. Passive diffusion is the major process through which drugs are absorbed into the body. Active transport is a process that uses energy to actively move a molecule across a cell membrane and is often involved in drug excretion in the kidney. Glomerular filtration is the passage of water and water-soluble components from the plasma into the renal tubule.
Answer:
The diagram represents the Law of Dominance
Explanation:
Any particular trait can be dominant or recessive in an individual who is heterozygous for it depending on their inheritance pattern from the parent genotype. Although the individual will be carrying the recessive allele in their genetic code too, it is only the dominant phenotype that is expressed. The dominant trait is represented by the capital letter whereas the recessive trait is represented by a small case letter.
The electrons surrounding an atom are located in regions around the nucleus called “energy levels”. An energy level represents the 3-dimensional space surrounding the nucleus where electrons are most likely to be. The first energy level is closest to the nucleus.
The structure of the plasma membrane makes this type of transport necessary for fluids is discussed below:
<h3>What do you mean by phospholipid membrane?</h3>
The membrane that divides the interior of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and is present in all cells. A cell wall is affixed to the plasma membrane on the exterior of bacterial and plant cells.
Because water and other polar or charged substances cannot easily traverse the hydrophobic core of the membrane, the phospholipid bilayer created by these interactions serves as an effective barrier between the interior and exterior of the cell.
