 Best Answer:<span>  </span><span>A karyotype is an actual photograph of the chromosomes from one cell. Karyotypes are usually done using blood cells, fetal skin cells (from amniotic fluid or the placenta) and occasionally bone marrow cells. While a karyotype is used to confirm that a person has Down syndrome due to an extra chromosome number 21, it actually gives much more information. 

From a patient’s perspective, a karyotype is a simple blood test. But what happens to the blood after it is collected is actually quite complex. This step by step guide will help you understand why it takes so long (up to a week) to get karyotype results. 


GENETIC DISORDERS 
What a karyotype tells us 

Karyotype analysis determines the number of chromosomes in the cells and whether there are any pieces of chromosomal material that are missing, extra, or rearranged. Any variation from the normal chromosome number and arrangement can have implications for a person's fertility and the risk for having a baby with birth defects. The following chromosomal conditions can be detected by karyotype analysis: 



Down syndrome (an extra 21 chromosome) 

Turner syndrome (females with only one X chromosome) 

Klinefelter syndrome (males with two X chromosomes and a Y chromosome) 

Other sex chromosome conditions, such as XXX or XYY 

Any other aneuploidy, which is an extra or missing single chromosome 

Triploidy, which is an extra set of chromosomes, so there are three of each and 69 total 

Mosaic chromosome conditions, in which a portion of the cells show an abnormal number or arrangement of chromosomes and a portion show a normal number and arrangement 

Translocations, which are rearrangements of the chromosome material 

Large missing or extra pieces of chromosome material that are visible under a microscope 



What a karyotype cannot tell us 

There are many genetic conditions that are the result of single gene mutations. Additionally, there are many genetic conditions that are caused by multiple genes interacting. These conditions cannot be detected by chromosome analysis. Examples of conditions that cannot be detected by karyotyping are: 



Very small deletions of the chromosomal material 

Very small duplications of the chromosomal material 

Some very subtle chromosome rearrangements 

Cystic fibrosis 

Tay-Sachs disease 

Sickle cell disease 

Dwarfism 

Breast cancer 

Cleft lip/palate 

Heart defects 

These are only a few examples. The complete list would contain thousands of genetic conditions that cannot be detected by chromosome analysis.</span>

Nitrate acts as a poison by interfering with oxidative enzymes. oxidizing hemoglobin to methemoglobin, which cannot carry oxygen
xxMikexx [17]

Explanation:

Methemoglobin (metHb) is an oxidized derivative of hemoglobin in which heme iron is in the ferric (Fe3+) or oxidized state rather than the ferrous (Fe2+) or reduced state. Small amounts of methemoglobin normally are formed daily, associated with the release of oxygen from hemoglobin (auto-oxidation).

Methemoglobin cannot bind oxygen, which means it cannot carry oxygen to tissues. It is bluish chocolate-brown in color. In human blood a trace amount of methemoglobin is normally produced spontaneously, but when present in excess the blood becomes abnormally dark bluish brown. The NADH-dependent enzyme methemoglobin reductase (a type of diaphorase) is responsible for converting methemoglobin back to hemoglobin.

Normally one to two percent of a person's hemoglobin is methemoglobin; a higher percentage than this can be genetic or caused by exposure to various chemicals and depending on the level can cause health problems known as methemoglobinemia. A higher level of methemoglobin will tend to cause a pulse oximeter to read closer to 85% regardless of the true level of oxygen saturation. An abnormal increase of methemoglobin will increase the oxygen binding affinity of normal hemoglobin, resulting in a decreased unloading of oxygen to the tissues.

CAN ANYONE HELP WITH THIS SCENARIO :(
Zanzabum
You can write the argument but I’ll list some stuff to help you write it out

•These warnings should be provided for the safety of people who buy their products because if they’re not, then the company should be held accountable for the deaths and or injuries.
This is because if they’re selling products without safety regards, they are selling dangerous products to people including children, which is Illegal.
The dad on the other hand did nothing illegal. He simply bought this product feeling safe to leave it with his child because there were no hazards or warnings of any kind, and BAM! It killed his child.
Therefore leaving the death of the child in the Companies hands.

•if their product does not contain a warning/hazard ( choking )of some sort, they’re technically saying that the child does not need to be supervised while being with that toy.
The dad felt no need to supervise the kid with the toy because there were no warning signs provided on it.
Therefore, leaving the safety in the playskool’s hands.

The dad did nothing wrong here. Since there were no warnings provided. As warnings are to warn those of danger who buy the product. Since no warning was clearly provided, then the safety of his child was not held towards him.

The company on the other hand, failed to do their job which was simply putting safety reguardes on children’s toys. Since that wasn’t provided, then that makes them (the greatest of the product without safety hazards) the killer of the baby.

- I’m sorry it’s so long and I tried but couldn’t think of anything else that would help defend the dad but I hope it helps you write your argumentative essay or whatever it is!
