What are three ways a biologist's research is different from an astronomer's?

A biologist's research focuses on living organisms, exploring their structures, functions, interactions, and evolution, while an astronomer's study involves celestial bodies and the universe's physical phenomena. Biologists often conduct experiments in laboratories or field studies to observe biological processes, whereas astronomers typically utilize telescopes and computational models to analyze data from light and other signals emitted by celestial objects. Additionally, biologists may investigate ecological relationships and genetic variations, while astronomers examine cosmic events and the laws of physics governing space.
