Write about Richard Ebright’s discovery of a hormone. How did he continue his
research on Monarch pupa?
Answers
Explanation:
Ebright initiated his research on the monarch pupa by studying the purpose of the twelve gold spots on its body. He discovered that these spots produced a hormone which helped in butterfly's full development. ... He cultured the hormones and identified its chemical structure. It led to his theory of cell life.
hope it helps you dear friend........ ☺ ☺ ☺ ☺

Answer:
In his second year at high school, he began the research that led to the discovery of an unknown insect hormone. Indirectly, it also led to his new theory on the life of cells. He tried to find the purpose of the twelve tiny gold spots on a monarch pupa. Along with another excellent science student, he built a device which showed that the spots were producing a hormone necessary for the butterfly’s full development. This project won the first place in the county fair and also an entry into the International Science and Engineering Fair, where it was adjudged the third best in zoology.
As a high school junior, he continued his advanced experiments on the monarch pupa. His project won first place at the International Science fair.
In his senior year, he grew cells from a monarch’s wing in a culture and showed that the cells would divide and develop into normal butterfly wing scales only if they were fed the hormone from the gold spots. That project won first place in zoology at the International Fair.
The summer after his freshman year at Harvard, Richard worked on the hormone secreted from the gold spots, and was able to identify the chemical structure of the hormone. During his junior year, he got the idea for his new theory on the life of cells. Along with his room-mate, James R. Wong, he worked on his theory and wrote a paper explaining the same.
