Some birds on the Galapagos Islands build nests in trees, while others hide eggs in rock crevices. What could account for this difference in nesting behaviors?
Answer:
Food habits, predators.
Explanation:
The biggest reasons are food habits and predators, most birds who nest on the ground either can't fly or use this to be closer to their food. A ground bird (Like quail) can fly but choose to be more ground-based birds.
Most of the time it's because these birds forage for food like ground insects, seeds from the brush that grows on the ground, or fallen fruit.
Most birds that live in the trees feast on seeds, leaves, or insects found close to where they choose to nest. They may also want to escape any predators that may be towards the ground.

There is a famous psychology experiment where people sit in classroom in such a way that the person on either side of you can't hear what you say. This works best with more than 20 people.
The first person composes a sentence that has 3 facts in it. He whispers it to the second person who relays it to the third until the last person is told. The point of the experiment is to show that the last person isn't normally able to correctly repeat the 3 facts. In fact, most often what is given is quite mixed up and incorrect.
That's what's wrong with eye witness accounts. You can be certain of what you saw. You can also get it all mixed up.
Using the following nucleotide sequence, predict the complementary strand sequence:
5'-TTAAACCCGTTGGAAC-3'
5'-AATTTGGGCAACCTTG-3'
3'-AATTTGGGCAACCTTG-5'
03-CCGGGTTTACCAAGGT-5'
0 3'-TTAAACCCGTTGGAAC-5'
The predicted the complementary strand sequence for 5'-TTAAACCCGTTGGAAC-3' is 3'-AATTTGGGCAACCTTG-5'.
What is DNA?Deoxyribonucleic acid or DNA is a double helix molecule composed of two complementary strands.
According to the base pair rules, Adenine pairs with Thymine and Guanine pairs with Cytosine.
In conclusion, the predicted the complementary strand sequence for 5'-TTAAACCCGTTGGAAC-3' is 3'-AATTTGGGCAACCTTG-5'.
