We know that by the process of gradual and continuous change, living organisms have evolved. After a number of experiments, scientists have established that genes are the segments of DNA. These DNA carries genetic information from generation to generation. Richard Ebright worked on his basis. He raised flock of butterflies and raised the eggs of female Monarch. He studied the various stages of female Monarch. He further studied the cause of a viral disease that killed all Monarch caterpillars. Next he tried to find similarities between viceroy butterflies and monarchs. Study of insect’s hormone further give a new theory on the life of cells. They found the hormone behind butterfly’s full development. Thus, all these experiments led him to form a theory that cells grew from a monarch’s wings. The cell would divide and grow in a normal butterfly. If they were fed into a hormone from the gold spots. Thus, he proved a new cell theory which formed the blue print of DNA.
If I am given a chance I would like to work in the sphere of stem cell which has a very wide range and would be a great keep for future.
Science involves experiments, analysis, hypothesis and conclusions. By simply reading we can just get facts but cannot get the reasons behind a particular result. Many diseases which were thought to be incurable in the past have been overcome by means of scientific inventions and discoveries. SubjecRead more
Science involves experiments, analysis, hypothesis and conclusions. By simply reading we can just get facts but cannot get the reasons behind a particular result. Many diseases which were thought to be incurable in the past have been overcome by means of scientific inventions and discoveries.
Subjects like History or Economics may not be regarded as science in vague terms. But if we go deep in these subjects, we find that Economics is a science of human behaviour and paradoxes. Either it is observing of human behaviour or historical building. It is the experiment which enables us to form scientific theory.

Edbright realizes that mere display of something does not mean science. To win at a science fair he will have to do real experiments. He said that his entry was slides of frog tissues under the microscope while other who had won had tried to do real experiments. For more answers visit to website: htRead more

Richard Ebright’s mother helped him by encouraging his interest in learning. She took him on trips, bought him telescopes, microscopes, cameras, mounting materials and other equipments, and helped him in many other ways. He was her whole life after his father died.

Richard Ebright’s mother helped him by encouraging his interest in learning. She took him on trips, bought him telescopes, microscopes, cameras, mounting materials and other equipments, and helped him in many other ways. He was her whole life after his father died. If Richard did not have anything to do, she found things for him to do and learn. Even the book that became a turning point in his life was given to him by his mother. Hence, it can be said his mother played a crucial role in the making of the scientist.
It all started with Richard Ebright’s interest in collecting butterflies. He also collected rocks, fossils and coins. His mother said that by the time he was in the second grade, he had collected all the twenty-five species of butterflies found around his home town. This would have been the end of hRead more

His mother said that by the time he was in the second grade, he had collected all the twenty-five species of butterflies found around his home town. This would have been the end of his butterfly collecting. Until his mother got him a book called “The Travels of Moarch X”. This book told him about the migration of monarch butterflies to Central America. It opened the world of science to an eager young kid. This proved to be turning point in the life of young Richard Ebright. He began to raise Monarch butterflies in the basement of his home, and study them in different stage of their development.
You must have read about cells and DNA in your science books. Discuss Richard Ebright’s work in the light of what you have studied. If you get an opportunity to work like Richard Ebright on projects and experiments, which field would you like to work on and why?
