In 1918, the Russian Tsar Nicholas II was deposed, and he and his family were reportedly executed and buried in a shallow grave.
Arte-miy333 [17]

Answer:

This can be evaluated with DNA test- by comparing the mitochondrial DNA (mtDNA)of the Tsar family with the woman-Anastasia. <u>Maternal DNA is inherited uninterrupted from generation to generation </u>

Explanation:

The living consort of Queen of Elizabeth ,Prince Philip, <u>is a grand nephew of Tsar Nicholas 11.</u> They  shared the same maternal ancestry.

Therefore, his   mitochondrial   must be maternal, and compatible with that of the Tsar Nicholar. Male children always inherit maternal mitochondria (mtDNA)and  passed from generations to generation.

T<u>he blood samples of prince Philip can be  taken, to extract the mtDNA,and matched  with the sample  of mtDNA obtained from the exhumed bodies of the Tsars,</u><u> </u>to reaffirmed the compatibility of the ancestry .  

If sample of the compatible mtDNA,  from price Phillip was compared with the mtDNA of the woman who claimed to be Anastasia, her claim can be validated.

Matched sample  shows she was the daughter, while negative result proves otherwise.

With regard to metabolic reactions, what does it mean when someone says a molecule has been "reduced"
Zina [86]

Example is conversion of NAD+ to NADH+ is an example of reduced in metabolism.

Explanation:

Oxidation and reduction or redox reaction means transfer of electron from one atom to another in a compound.

In photosynthesis and respiration redox reaction are seen.

The substance that gain the electrons in  metabolic reaction is said to be reduced.

In respiration process oxygen is being reduced. The NAD+ accepts hydrogen ion  and 2 e- to become NADH+H+. These are electron carriers.

The reactions can be seen in glycolysis, Kreb's cycle.
