Rosalind Franklin was a British biophysicist and X-ray crystallographer who made significant contributions to the understanding of the molecular structures of DNA, RNA, viruses, coal, and graphite. She is best known for her work on the X-ray diffraction images of DNA, which played a crucial role in the discovery of the double helix structure of DNA by James Watson and Francis Crick. Despite her groundbreaking work, Franklin did not receive the recognition she deserved during her lifetime, and her contributions were often overshadowed by her male colleagues. Franklin's work has since been acknowledged and she is now celebrated for her important contributions to the field of molecular biology. **

Small electric two-wheeler three-wheeler flatbeds with a roof typically have a compact design with a flatbed at the rear for carrying goods. They are usually equipped with a roof to provide protection from the elements. The vehicles are designed to be lightweight and maneuverable, making them suitable for navigating through crowded urban areas. They often have a simple and functional appearance, with a focus on practicality and efficiency for transporting goods in a small-scale urban environment. **

A two-wheeler mechanic master is a highly skilled and experienced professional who specializes in repairing and maintaining motorcycles, scooters, and other two-wheeled vehicles. They have extensive knowledge of the mechanical and electrical systems of two-wheelers and are capable of diagnosing and fixing a wide range of issues. These experts are often sought after for their ability to provide efficient and effective solutions to keep two-wheelers in top condition. **

No, a gas planet does not have a solid surface. Gas planets like Jupiter and Saturn are primarily made up of gases such as hydrogen and helium, with no solid surface to stand on. Instead, these planets have dense atmospheres that gradually transition into a liquid or slushy interior. **

Saturn does not have a solid surface like Earth. It is a gas giant composed mostly of hydrogen and helium, with no distinct solid surface to stand on. The planet's atmosphere gradually transitions into its interior, where pressure and temperature increase, eventually forming a dense core made of rock, metal, and ice. **

In general, a car is considered safer than a two-wheeler due to its enclosed structure, seat belts, airbags, and other safety features. Cars provide more protection in the event of a crash and are less susceptible to external factors such as weather conditions and road hazards. However, safe driving practices and adherence to traffic laws are crucial for both car and two-wheeler users to minimize the risk of accidents and injuries. **

No, new solid matter is not created on Earth through photosynthesis. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose (a type of sugar) and oxygen. The solid matter produced in this process is the glucose, which is used by the plant for energy and growth. The atoms in the glucose molecules come from the carbon dioxide and water that the plant absorbs, so photosynthesis does not create new atoms or solid matter. **

There could be several reasons why the new lawnmower Eco Wheeler 400 is not starting. It could be due to a lack of fuel or oil, a clogged air filter, a faulty spark plug, or a problem with the ignition system. It is important to check these components and ensure they are in proper working condition to troubleshoot and resolve the issue. If the problem persists, it may be necessary to consult the manufacturer or a professional for further assistance. **
