I'm sorry, but it seems like the question you provided is in Spanish and is asking for a response related to a specific scenario involving the color change of a lake due to cyanobacteria. The question also asks about the involvement of different natural sciences and the formulation of a hypothesis.
To answer the questions:
A. Why do you think more than one type of science is needed to study natural phenomena?
- Natural phenomena are complex and involve various aspects that can be better understood through the lens of different scientific disciplines. For example, studying the color change of a lake due to cyanobacteria would require knowledge from fields like biology, chemistry, and environmental science to fully grasp the causes and effects of the phenomenon.
B. Natural Sciences involved in this study:
- Biology: to understand the characteristics and behavior of cyanobacteria.
- Chemistry: to analyze the chemical composition of the water and the interactions causing the color change.
- Environmental Science: to study the impact of cyanobacteria on the ecosystem of the lake and potential implications for the environment.
C. Formulating a hypothesis:
- "Increased presence of cyanobacteria in Lake Coatepeque leads to a change in water color to blue turquoise due to the production of specific pigments during certain environmental conditions."
In scientific studies like this, a hypothesis serves as a proposed explanation for a phenomenon based on prior knowledge and observations. It guides the research process and helps in testing and verifying the underlying causes of the observed natural event.
