Create a page from a textbook on "{argument name="subject" default="Biology"}" used in a school in a "{argument name="worldview" default="Fantasy World"}". The content of the textbook must not be based on the real world, but must strictly adhere to the specified worldview. The content should be written in accurate Japanese, avoiding duplication of content and font corruption. The composition is a realistic photo of an open textbook taken directly from above, not an illustration.
