Some present-day bacteria use a system of anaerobic respiration characterized by an electron transport chain analogous to that f
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.

D) #recombinant=116+601+4+2+113+625=1462

   #nonrecombinant=2538+2708=5246

  RF=R/(N+R)=1462/6708=0.2

  E) I=1-Q

I-interference

Q-coefficient of coincidence

Q=O2Xo/E2xo(2xo-double crossovers)

O2xo=6

P=(distance from C1 to Sh/100)*(distance from Sh to Wx/100)

=(3.38/100)*(18.28/100)=0.006

E2xo=0.006*6708=40.248

Q=6/40.248=0.15

I=1-0.15=0.85
