A student claims that cellular respiration is essential to cells so that they have a means for getting rid of excess carbon diox
Phantasy [73]

The correct answer is "Cellular respiration does not consume carbon dioxide".

Cellular respiration refers to the set of chemical reactions by which cell harnessed energy from nutrients and convert it to ATP (also called as energy currency of the cell).

It is essential for the cell as it generates ATP which is used in all the processes such as DNA replication, repair, etc.

Cellular respiration uses oxygen and releases carbon dioxide as a waste product.

Oxygen is provided by air we inhaled and carbon dioxide is released as a part of exhaled air.

The general equation of cellular respiration can be written as:

C_{6}H_{12}O_{6} + 6O_{2}C

→ 6CO_{2} + 6H_{2}O + ATP6CO

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.
