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.
Answer:
D. X: Gene for sweeter fruit
Y: Apple tree DNA
Explanation:
The process that producing apple trees with desired trait of sweeyer fruits will require gene for sweeter fruit and apple tree DNA.
Genes are responsible for carrying traits or characterstics from parent to daughter, here the trait is sweetness and genes are must to carry this trait otherwise apple will lack sweetness.
DNA carry instructions which are required to develop, reproduce and survive by an organism. DNA undergoes several processes like replication, transcription and translation and share the DNA of male and female parent (sexual reproduction) to produce new organism or plant. hence, DNA of apple tree will be required.
Hence, the correct option is D.
Jb Kown, the anthropologist in question, compares the fieldwork settings by their <u>fight for equality.</u>
Such is the case in many countries around the world, South Korea at times struggles to maintain equality in all of its settings, such as in factories. Anthropologist jb Kwon researched factory workers and found that <u>inequality </u>is present in the form of job and wage distribution between men and women.
The anthropologist Jb Kwon compares this with the anti-racist work he took part in after the Micheal Brown incident in that they are both done to argue <u>for </u><u>equality </u><u>among all people</u>, regardless of <u>gender</u>, <u>race</u>, or <u>background</u>.
