Peter and rosemary discovered a natural ecosystem with an extreme climate, oscillating between cycles of intense drought and abundant rainfall, as well as an uncontaminated area that had never been explored by humans. This was an excellent location to study the evolution of Galapagos finches.
- For their outstanding long-term studies showing evolution in action in Galápagos finches, Peter and Rosemary Grant are renowned.
- They have shown that natural selection is responsible for the incredibly quick changes in body and beak size in response to variations in the availability of food.
- Due to the lack of predators or rivals for the finches, Daphne Major makes an excellent location for research.
- (The cactus finch is the only other finch on the island.)
- The weather, and consequently the availability of food, has a significant impact on the medium ground finch's capacity to survive.

Answer:
At sea level, air pressure is greatest because it is caused by the weight of the entire column of atmosphere at that altitude over that location. As altitude increases, the column of atmosphere gets shorter, and so less weight is pressing down at a given altitude, so atmospheric pressure is reduced.
Answer: Phosphodiester bond
Explanation:
The backbone of DNA consists of deoxyribose nucleotides linked by phosphodiester bridges.
The 3'-hydroxyl of the adjacent sugar of one deoxyribonucleotide is joined to the 5'-hydroxyl of the adjacent sugar by an internucleotide linkage called a phosphodiester bond.
Thus, phosphodiester bond is the answer
