In the 18th century, Italian biologist Lazzaro Spallanzani designed an experiment supporting the hypothesis that gastric juices are partly responsible for digesting food. Which human illness did Spallanzani's work eventually shed light on?
What is one way that scientists use imagination to guide their creativity when they conduct research?
One reason that multiple approaches are often taken to answer a testable question is that scientists
Charles Darwin developed the theory of evolution. Around the same time, Alfred Wallace also developed a similar theory of evolution. Both scientists studied different organisms. Which best describes the experiments of Darwin and Wallace?
Why are Lazzaro Spallanzani? ’s gastric juice experiments examples of creativity in science?
Charles Darwin developed the theory that explains how new species develop based on evidence from many different kinds of scientific inquiry. Darwin’s theory can only be valid if Earth is very old. The scientists who provided evidence for the earth’s old age were most likely

What is influenced by the differences in scientists’ educational and research experience?
The first electric generators used direct current, so they needed to be reversed manually on a regular basis in order to work properly. Nikola Tesla saw this as an inefficient way to produce electricity. As a result, Tesla used the idea of the rotating magnetic field, which had been developed by François Arago, to invent the induction motor, which reverses automatically. How is this an example of a scientist applying creativity to solve a problem?
