geniusboy [140]

Answer:

The correct answer would be:

Neither of these response options accurately features the anaerobic electron transport chain.

Explanation:

The anaerobic respiration system vibrated by an electron transport chain is a mechanism that anaerobic bacteria have to maintain their respiration.

This mechanism does not require oxygen in the atmosphere, that is why it is said to be an anaerobic mechanism.

Bacteria do not all need oxygen in the environment to live, some need that oxygen is not exactly present (strict anaerobes) or that it is at low partial pressures (facultative anaerobes).

This mechanism is very characteristic in its location since it is located in the inner membrane of the mitochondria, that is why it will decide to indicate that option as the correct one.

lawyer [7]

Answer:

DNA is the genetic material of all the living organism except some viruses. The structure of DNA consists of nitrogenous base, pentose sugar and the phosphate group.

Tube 1 - The nucleotide are linked together by phosphodiester bond. As these bonds are broken, the structure of DNA contains the individual complementary nucleotide are linked together by hydrogen bonds.

Tube 2 - The bond between the sugar and the bases are broken. The DNA structure consists of the phosphate group chain only with any pairing with the base.

Tube 3 - The DNA nitrogenous bases are adenine, guanine, thymine and cytosine that are linked together by hydrogen bonds. The agents break the hydrogen bonds. Now, the DNA structure consists of the single strand only.
