A field biologist who studies the behavior of birds in a rainforest most likely collects data through observation.
Rainforests are the areas with rich diversity of plants as well as animal species. The trees of rainforests are so long, broad and thick that they completely cover the canopy. They are also recognized by highest rainfalls. Rainforests are considered to be the oldest in the in the Earth's ecosystems.
Observation is the act of carefully watching any action or scenario in order to gain information. Observation can be turned into a formal activity when any data is collected through it for educational or experimental purposes.

Answer:
* Scientists use genes to explain why evolution happens.
Mercator projection, type of map projection introduced in 1569 by Gerardus Mercator. It is often described as a cylindrical projection, but it must be derived mathematically. The meridians are equally spaced parallel vertical lines, and the parallels of latitude are parallel horizontal straight lines that are spaced farther and farther apart as their distance from the Equator increases. This projection is widely used for navigation charts, because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course. It is less practical for world maps, however, because the scale is distorted; areas farther away from the Equator appear disproportionately large. On a Mercator projection, for example, the landmass of Greenland appears to be greater than that of the continent of South America; in actual area, Greenland is smaller than the Arabian Peninsula.
Answer:
The most closely related are amphibians and reptiles.
The least related are amphibians and mammals
Explanation:
Amphibians broke off from reptiles, birds, and mammals around 260 millions years ago and next up are the reptiles which broke off around 225 million years ago. So they are the most closely related
Mammals are the last to break off, around 200 million years ago. So they are the least related to amphibians.
Elliptical galaxies. I hope thats correct.
