Oxygenation of fetal blood occurs in the?
Oxygenation of fetal blood occurs in the placenta, where the mother's bloodstream and the fetus's bloodstream come into close proximity but do not mix. Oxygen from the mother's blood diffuses into the fetal blood, while carbon dioxide diffuses from the fetal blood into the mother's blood for elimination.
Why is a very small trace of blood enough for DNA fingerprinting?
A very small amount of DNA (eg. from blood) is enough for DNA fingerprinting because of the use of amplification techniques.Polymerase Chain Reaction (PCR) is an amplification technique that is commonly used for this purpose. It can begin with a very small amount of DNA and make copies of this - resulting in enough DNA to run multiple tests.
When the lungs do not function in a fetal pig what takes over their function?
The placenta. Deoxygenated blood flows to the placenta where the carbon dioxide is removed and oxygen added. Oxygen rich blood returns to the fetus. Blood is carried to and from the fetus by the umbilical cord.
What organ in a fetal pug removes nitrogenous wastes from the blood?
Kidneys filter nitrogenous waste from the blood.
Is polymerase chain reaction used to amplify DNA from a fossil a fetal cell or a virus?
The PCR reaction can be used to amplify DNA from all three sources mentioned. PCR relies on the use of short stretches of DNA that are 6 - 12 bases long to attach to the target DNA (the source where the DNA is coming from) so that the polymerase enzyme can make copies of the target DNA. As long as these primers are available (they can be commercially purchased in many cases), PCR can be carries out on fetal cell DNA and viral DNA. Fossil DNA however, may have undergone degradation. DNA has to be of a certain purity for PCR to work. If the fossil DNA had degraded or broken down, PCR cannot be carried out.

What is the genetic basis of blood in simple terms?
Actually, red blood cell have no DNA, so for them the is no genetic basis. While blood cells do have DNA and interestingly enough they are they cells that protect us. Does that help???

What precautions can be taken to prevent fetal exposure to HIV-infection?
Precautions for preventing fetal exposure to HIV-infected maternal blood include avoiding: amniocentesis, fetal scalp blood sampling, premature rupturing of the fetal membranes.
What is the source of nutrients in fetal blood?
Blood from the mother is used by the fetus.
What carries blood to the forelegs in a fetal pig?
no
What fetal blood vessel has the highest oxygen concentration?
The umbilical vein carries oxygen-rich blood from the placenta to the fetus, making it the fetal blood vessel with the highest oxygen concentration.
Which fetal blood vessels take blood to and from the placenta and to and from the fetus?
umbilical cord
Fetal hemoglobin or hemoglobin F does not bind oxygen as well as adult hemoglobin hemoglobin A?
FalseAdult hemoglobin has less affinity for oxygen than fetal hemogloblin. That is why, as an adult female's blood passes BY the placenta, the oxygen diffusses into the fetal blood. Likewise, adult blood, having explelled the carbon dioxide during exhalation, has less concentration of carbon-dioxide than the fetal blood, so it diffuses out of fetal blood into the adult blood. That way, the fetus doesn't need respiration as an oxygen source, nor as a way to rid of waste and carbon dioxide.
What are some signs of fetal distress?
There are many signs of fetal distress such as cramping, umbilical cord issues, gaining weight, fetal movements, high blood pressure, and fetal heart rate.
What prenatal tests can detect toxoplasmosis?
Prenatal tests for toxoplasmosis include a blood test for maternal antibodies; testing of the amniotic fluid and fetal blood; and, fetal ultrasound.
Is the non invasive paternity test accurate?
Non invasive prenatal paternity testing can be done by collecting a blood sample from the mother. Fetal DNA makes its way into the maternal blood stream through the placental wall which envelopes the unborn baby. A particular vein has been found to be particularly rich in fetal DNA. This procedure carries huge advantages over prenatal testing procedures such as amniocentesis or CVS. The non invasive prenatal test is totally risk free.
