Darwin's finches are a traditional illustration of an adaptive radiation. Their ancestor came on the Galapagos Island about two million years ago. With time Darwin's finches have developed into fifteen different species separated on the basis of beak shape, body size, and feeding and song behavior.
The population of finches possesses the tendency of evolving rapidly in response to a changing environment. However, they can also get extinct in condition if the weather fluctuates too briskly between the dry and wet seasons. This would most likely take place due to the immigration of genes and mutations within the genes that are conducted on to the next generations.

Answer:
D
Explanation:
<em>The correct option here would be</em><em> D</em><em>.</em>
The endomembrane system refers to a group of membrane-based organelles whose primary function is to synergistically work together to modify, package, and transport lipids and proteins. The system includes organelles such as the lysosome, the nuclear envelope, the endoplasmic reticulum, and the Golgi apparatus.
For an endomembrane system function involving a protein, the protein would first of all need to be synthesized by the ribosome - the free ones or the ones attached to the rough endoplasmic reticulum. Thereafter, the synthesized protein would then be folded or packaged into transportable vesicles. The vesicles are then received by the Golgi apparatus which further modifies the proteins before transporting them accordingly.
Hence, the correct order of a typical endomembrane system function would be:
- <em>Ribosomes on the RER synthesize proteins.</em>
- <em>Proteins are packaged into transport vesicles.</em>
- <em>Golgi apparatus receives transport vesicles from the RER.</em>
- <em>Proteins are modified by the Golgi apparatus.</em>
- <em>Modified proteins may be secreted from the cell by exocytosis.</em>
