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

ound in aerobic organisms. Which of the following correctly characterizes the anaerobic electron transport chain?
a. It uses oxygen as a final electron acceptor.
b. It is embedded in the outer mitochondrial membrane rather than the inner mitochondrial membrane.
c. It establishes a proton gradient between the cytoplasm and the extracellular fluid.
d. It establishes a proton gradient between the intermembrane space and the cytoplasm.
e. None of these answer options accurately characterizes the anaerobic electron transport chain.

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.

Coyotes and dogs have been placed into different species. however, they can mate and produce viable, fertile offspring. what wou
Ostrovityanka [42]
That fact can be explained by the similarity in their genes. 

Dogs and coyotes are from the same class, family and genus (Mammalia, Canidae, Canis).
This is almost enough for their offspring to be viable. But if the DNA is similar (which it is) offspring the chances of viable and fertile offspring is high almost at 100%.

Hope it helped,

In dogs, genes A and B are required for scent.Individuals homozygous for either one or both of the nonfunctional recessive allel
andrew11 [14]

Answer:

6/16 dogs will not be able to smell.

Explanation:

Genes A and B are considered for scent smell.

Individuals homozygous for either one or both of the nonfunctional recessive alleles are not able to smell.

The final cross would be AaBb x AaBb which has outcome of;

Individual with homozygous nonfunctional recessive alleles (bold ones):

  • One nonfunctional recessive alleles: Aabb, aaBB, aaBb, Aabb, aaBb (5/16)
  • Two nonfunctional recessive alleles: aabb (1/16)
  • All nonfunctional recessive alleles: 6/16 dogs that could not smell scents
