A scientist asks a question and discovers that increased temperature decreases the number of offspring that an organism
produces. Then, the scientist asks a new question about the impact of climate change on the species because
the scientist's first question was not a scientific question
the scientist modified the hypothesis for the investigation.
the results of the investigation led to new scientific questions.
questions about the impact of temperature reflect an opinion

In science, hypotheses are created mainly to understand a certain phenomenon. This requires the generation of multiple questions to explore the topic thoroughly.

A scientist cannot explain a phenomenon with only one question or one set of experiments. In fact, scientists need to design different experiments to manipulate different variable and determine which of those has a significant impact. Then, after the first question has been answered, other questions are going to arise and other experiments will need to be performed to provide facts and evidence. This is also how a theory is developed or proposed.

In this case, the scientist demonstrated that an increased temperature decreases the number of produced offspring in a certain species. Now, he/she wants to explore how this species will cope with the increased temperatures that climate change will bring. This new question will allow him/her to understand the behavioral or physiological plasticity the species has and whether it will be able to adapt to future environmental conditions.
