How is an experiment different from observation? Give examples of the use of these methods in biological research. What is their significance?

An experiment, in contrast to observation, is associated with the creation of special conditions, which the experimental scientist consciously selects and controls during its course.
Observation of the behavior of chimpanzees, observation of the growth and development of one plant.
With the help of experiments, scientists can cross animals, find out how various environmental conditions affect organisms.
Observation involves a focused perception of objects or phenomena, but without the active intervention of the observer.
The experiment allows us to achieve the repeatability of the same conditions and, unlike other research methods, reveals the very essence of the object or process.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
