<u>Answer:</u>

<em>Homologous structures are organs of animals which are same in terms of basic structure but differ entirely in function.  </em>

<u>Explanation:</u>

Homologous organs indicate common ancestry among organisms and the functions differed as apart of adaptations according to the environment. Since the same structure has developed along different directions homologous structures indicate divergent evolution.

There are several examples of homologous organs.

Forelimbs of mammals like human bat cheetah whale etc are homologous structures. They have the same structure but entirely different functions. Whales use forelimbs for swimming, bats use forelimbs for flight and cheetah uses forelimbs to run.

Answer: Homologous structures are animals' and organisms' organs or skeletal elements. Homology was explained by Charles Darwin's theory of evolution.

Explanation:

Homology is showing the relationship between organs or skeletal elements of different organisms. Those characters, actually Homologous structures, are inherited from their common ancestor.

<em>Why is this important for the evolutionary relationship which Charles Darwin's theory is showing?  </em>It's important because nowadays all those differences were happened during the evolutionary divergence of organisms.

  • Examples of homologous structures:  mouthparts of insects, worms, and snakes, animal forelimbs...

Nothing is unique in nature so homology is everywhere.

The French scientist Jacques Monod famously said, "Anything found to be true of E. Coli must also be true of elephants." How is
8090 [49]

Answer:

The correct answer is : prokaryotic organisms like E. coli and higher organisms share common ancestor.

Explanation:

E. Coli is a prokaryotic organism or bacteria. On the metabolic level these organisms share similar homology with the higher organism other than this these organisms also show same core functions with higher level organisms such as elephant.

These similarities suggest that the all the living organisms share a common ancestor. The french scientist Jacques Monod statement "Anything found to be true of E. Coli must also be true of elephants." is also based on this notion.
