Answer:
B) speciation.
Explanation:
The Galapagos island is known for the different varieties of finches (species of birds) which could be distinguished on the basis of different beak shapes and size.
This is the result of the selection pressure which led to the divergence of the species on the island through a mechanism called adaptive radiation.
Since the adaptive radiation leads to the formation of different species on the same island, the process of formation species is known as the speciation.
Thus, speciation is the correct answer.
Answer:
The answer was A
It's a Heterotroph
It's means they eat thing outside of themselves instead of producing their own food.
I believe it's correct
Explanation:
Cells are limited in size by their surface area and volume.
A cell does not possess a mouth, lungs and digestive system. Every process has to happen directly or indirectly through the cell membrane. The relationship between the volume of cell contents and the surface area of the cell membrane becomes the limiting factor in how big a cell gets to be.
If it gets too big it may starve due to lack of incoming nutrients, or poison itself because it can not get rid of waste rapidly enough.
