The chemical reactions involved in respiration in prokaryotic and eukaryotic cells are virtually identical. In eukaryotic cells,
Ipatiy [6.2K]

Answer:

d. on the plasma membrane

Explanation:

According to the endosymbiotic theory the origin of mitochondrion is from the prokaryotic organism: primitive host cell (future eukaryotic cell) engulfed prokaryotic cell (endosymbiont) that provided the functions that evolved into mitochondria. Both of them had benefits: the endosymbiont gained protection and  some essential nutrients from the host, while host had the energy and oxygen source from the endosymbiont.

So, the plasma membrane of the endosymbiotic prokaryotic cell became the membrane of the mitochondrion.

In 1918, the Russian Tsar Nicholas II was deposed, and he and his family were reportedly executed and buried in a shallow grave.
GaryK [48]

Answer:

By making a paternity test by Short tandem repeats, or STRs (microsatellites).

Explanation:

Short tandem repeats, or STRs, are microsatellites consisting of repeated sequences of 2 to 6 base pair length monomers  in tandem, and most of them have a high degree of polymorphism. Half of an individual microsatellites are inherited by each parent, and they can be assesed by PCR amplification and further electrophoresis.

In this case, you would try to recover a bone from the remainings of the woman, the Tsar and his wife, since the rest of the latest were in a shallow grave with many different individuals. Preferably, you should manipulate this samples in an ancient DNA facility (aDNA) with proper techniques. You clean the bone samples, drill them, and from internal bone powder make a DNA extraction. After this, you perform a series of PCR targeting a panel of STRs, and electrophoresis. If the woman claim is true, half of her microsatellites should have correspondence with the Tsar, and half with the ones of his wife.
