The bugs evolved beak lengths that were adapted to their host plant.
Explanation:
This is an interesting case of evolution in which bugs evolved (changed) quickly over a few generations. In less than 50 years the bugs evolved beak lengths to match the size of the new host plant’s seed pods. The bugs were not used to live out of that plant but they started feeding on it and then they changed some of their characteristics.
Prokaryotic cells have a cell wall surrounding their cell membrane .The Prokaryotic cells don't have a well defined nucleus .The genetic material of the cell is basically naked and not enveloped by the Nuclear membrane .
Eukaryotic cells don't have a cell wall surrounding their cell membrane. The Eukaryotic cells have a well organised nucleus .The genetic material of the cell is surrounded by nuclear membrane or nuclear envelope.
Both Eukaryotic and prokaryotic cells have DNA.Both have a plasma membrane or cell membrane.
