<h2>Down Syndrome</h2>
Explanation:
Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21
- Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21
- Down syndrome is usually caused by an error in cell division called nondisjunction which results in an embryo with three copies of chromosome 21 instead of the usual two
- Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separates
- With development in embryo the extra chromosome is replicated in every cell of the body;this type of Down syndrome which accounts for 95% of cases is called trisomy 21
- Maternal age is the only factor that has been linked to an increased chance of having a baby with Down syndrome resulting from nondisjunction;here environmental agents such as drugs, chemicals, and radiation act as mutagens which induce mutation in the fetus
Phospholipid can occur in a polar cell.

The answer to the first question is a.
Answer:
Because liquids flow freely, they take the shape of the container they are in, but have a definite volume. Like liquids, the shape of a gas changes with the container. This is because the atoms in a gas move rapidly and freely to fill any available space. Unlike liquids, the volume of a gas changes depending on the container it is in.
Explanation:
Answer: Maybe if you knew the def's you could answer it.
Initial Decay – Bacteria located mainly in the lower intestine begin decomposition, giving a greenish color to the lower abdomen. Stage 2: Putrefaction – Bacteria grow throughout the body, releasing gases, including cadaverine, which in turn bloat the body and cause unpleasant odor.
putrefaction
the process of decay or rotting in a body or other organic matter.
Black putrefaction occurs, which is when noxious odors are released from the body and the parts of the body undergo a black discoloration. 2 weeks: The abdomen is bloated; internal gas pressure nears maximum capacity. 3 weeks: Tissues have softened. Organs and cavities are bursting.
Fermentation occurring in putrefaction and apparently in the digestion of herbivorous mammals in which butyric acid is produced by certain chiefly anaerobic bacteria acting upon various organic substances (such as lactic acid or butter)
A dry body will not decompose efficiently. Moisture helps the growth of microorganisms that decompose the organic matter, but too much moisture could lead to anaerobic conditions slowing down the decomposition process
