Detailed explanation-1: -Answer: It is true that without the support and motivation of his mother, Richard Ebright would not have been a successful scientist. It was his mother who recognised his driving curiosity and bright mind. She always encouraged his interest in learning.
Detailed explanation-2: -His mother helped him by writing a letter to Dr. Urquhart and allowing Ebright to attach light adhesive tags to the wings of the monarchs to be sent to the doctor. She was the one who gave him the book which fueled his interest in science.
Detailed explanation-3: -Answer: Ebright made valuable contributions to the world of science. He discovered an unknown insect hormone and also determined how the cell could read the blueprint of its DNA.
Detailed explanation-4: -The two contributions of Ebright to the world of science were ● Ebright built a device that showed that the spots on monarch butterflies wings produce a hormone that is necessary for the growth of the butterfly. His other important contribution was his study of how cells read their DNA.
Detailed explanation-5: -He found that cells would divide and grow into a normal butterfly if they were fed a hormone that was found in the gold spots of the monarch. Hence, he proved a new theory which formed the blue print of DNA. The experiments conducted by Ebright amply show him to be a successful scientist.
