Answer and Explanation:
Nondisjunction occurs when homologous chromosomes fail to segregate during anaphase I or sister chromatids fail to segregate during anaphase II. The result is an addition or loss of one or more chromosomes. Nondisjunction is associated with disorders like Down's syndrome due to an extra chromosome, Klinefelter's syndrome or Turner's syndrome. These phenomenon where one has three members of homologous chromosome is called trisomy.
Blood pressure
This is indicated in Starling's Hypothesis in which there is fluid movement due to filtration across the wall of capillary. This is dependent between hydrostatic pressure gradient and oncotic pressure across the capillary. The balance of these forces allow the net driving pressure for filtration. The net fluid influc is proportional to this net driving pressure. The leakage of proteins across the capillary membrane has important effects and has corresponding cause in the balance of forces.
One reason would be the increased chance of Down syndrome
Antigen presenting cell is a cell phagocytizes an antigen and displays fragments of it on its surface for recognition by other cells of the immune system
<h3>What is Antigen presenting cells?</h3>
An antigen-presenting cell refer to an immune cell that detects, engulfs, and pass a message to the adaptive immune response about an infection. When a pathogen is detected, the antigen presenting cells will engulf the pathogen and digest it to form many different fragments of the antigen.
Therefore, Antigen presenting cell is a cell phagocytizes an antigen and displays fragments of it on its surface for recognition by other cells of the immune system
