Answer:
The reason why only 3 out of the 22 possible autosomal trisomies are seen in newborns, is because the rest of them are chromosomal abnormalities not compatible with life and thus an spontaneous abortion occurs. The embryos suffering from these trisomies do not survive for more than a few weeks in the uterus, so the miscarriage often goes unnoticed for the mother as she may not have realized she was pregnant.
The only trisomies that are allow fetuses to be born are: Patau Syndrome (trisomy 13), Edwards Syndrome (trisomy 18), and Down Syndrome (trisomy 21). Out of these three, people with Down Syndrome have the largest life expectancy.
The growing area of genetics and gene therapy may allow psychologists to focus on prevention of psychological disorders rather than on treatment only.
<h3>What is gene therapy?</h3>
- Utilizing a gene or genes to treat, prevent, or cure a disease or medical condition is known as gene therapy.
- Gene therapy frequently involves replacing a damaged gene in a patient's cells with a healthy copy of that gene or inserting new copies of a damaged gene.
- Ex vivo, in vivo, and in situ gene therapy are the three main subtypes. Ex vivo gene therapy involves removing the patient's affected cells and modifying them genetically, either by introducing the therapeutic gene or through other means, to rectify the disease's phenotype.
- Gene therapy aims to address genetically based disorders (the source).

Mitochondrial electron transport is a series of reactions which take place in the mitochondria and which leads to the formation of ATP in the cell. When the electron transport chain is exposed to carbon monoxide, the gas will inhibit the cytochrome C oxidase and stop the production of ATP inside the cell. This will leads to the death of the cell.
There are three types of hormonal release control (increase or decrease production), which is stimulated by
1. specific molecules, minerals or particular nutrients ( chemical regulation)
2. other hormones (hormonal regulation)
3. input from nervous system. (neural regulation)
If the inhibition is caused by a different hormone, it would be considered hormonal regulation. In the given example, the hormone is produced in the target organ.
However, if the inhibition is due to the accumulation of the hormone itself, then it is an example of a <em>negative feedback</em>.
