Charles Darwin's finding that the finches on the Galapagos islands looked different from the mainland finches despite their common ancestry from South America is an example of <u>C. adaptive radiation</u>.
<h3>What is common ancestry?</h3>
Common ancestry refers to blood relationships. Thus, two species may have common ancestry if they are related by blood.
According to Charles Darwin, common ancestry explains the similarities between different species.
However, a rapid increase in the number of species with a common ancestor, characterized by great ecological and morphological diversity results from adaptive radiation.
Thus, Charles Darwin's finding that the finches on the Galapagos islands looked different from the mainland finches despite their common ancestry from South America is an example of <u>C. adaptive radiation</u>.

Answer:
Explanation:
chloroplasts
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
Answer:
An amino acid activates the repressor so that the repressor binds to the operator and prevents transcription.
Explanation:
In an operon, promoter is followed by operator which is finally followed by the structural genes to be transcribed. RNA Polymerase binds to the promoter and initiates transcription. A repressor can negatively control the transcription process by binding to the operator so that the RNA Polymerase is not able to move forward and transcription is halted.
For example: in trp operon, tryptophan amino acid binds to the repressor molecule which leads to change in repressor's shape. The repressor is now able to bind to the operator and prevent transcription.
The correct answer to your question is A. :)
