Scientists observe a wide range of phenomena depending on their field of study, but common things they may observe include changes in temperature, patterns in data, behavior of organisms, chemical reactions, and the effects of certain stimuli on their subjects. The goal of these observations is to gather data and draw conclusions that help further our understanding of the natural world.
The scientist should use an electron microscope

An artificial situation created by a scientist to observe the consequences of specific changes is called an experiment. In an experiment, the scientist manipulates variables to test hypotheses and determine the impact of those changes under controlled conditions. This method allows for the identification of cause-and-effect relationships in the natural world.
Microscope. A scientist might use a microscope. Well actually, it depends on the size of the animal. If it is microscopic, then scientists might have to observe it using it using a microscope. If it can actually be seen, then scientists mught actually take a sample of it back to the labratory to observe physically.

It allows a scientist to measure the wavelength of light.

A scientist studying how populations evolve would most likely observe organisms with short generation times, high reproductive rates, and large population sizes, such as bacteria or fruit flies. These organisms allow researchers to observe multiple generations quickly and see how genetic changes occur over time within a population.
Experiment- "In a experiment, the scientist deliberately makes certain changes in the world about him so that he can observe the consequences."
