Answer:
I think that birds have different bill lengths because of their habitats and their diet. Also natural selection and evolution has also played a factor due to the fact that birds have not always looked the way that they do now, for example the Archaeopteryx a bird that lived around the time of the dinosaurs had a shorter and more powerful bill to grind insects and small mammals
Explanation:
Apples are drawn to a massive object, like the earth, and fall down under a gravitational constant. On the other hand, planets revolve around a more massive object under the same premise. It’s the same idea, just one follows a linear path, and the other has a uniform circular motion path because other forces are acting on it. In other words, the planets ARE still falling, but the sun is also pulled by them so they just keep dancing.
The seasonal movement of animals from one place to another (usually occurs in species with ability to flight and in large amount
Answer:
Robert Hazen’s studied enviromental and biological processes that might have been critical for life, and also for the formation of approximately two-thirds of Earth's mineral species (see Hazen et al., 2008; Gonzalez & Richards 2020)
.
Explanation:
Hazen provided evidence about how first organic molecules were generated on the primitive earth millions of years ago. He observed that high-pressure hydrothermal vents may provide food for underwater ecosystems. It represents a piece of critical evidence on the origin of life.
You can read these articles that are certainly clarifying in the description of his experiments and discoveries:

It’s c cause I know and I was just too lazy to type the word lol
