forms of what we now call DNA. DNA wasn’t just discovered by 1 or 2 scientists but rather a group of scientist over many different years. She starts off by telling us how Swiss physiological chemist Friedrich Miescher discovered the early parts of DNA and how Russian biochemist Phoebus Levene began laying the groundwork. From there the article goes on to show how other scientists went onto strengthen their formula until scientists James Watson and Francis Crick came along and formulated their own

sending Cassini to the f-ring of Saturn we can observe how planets form and interact with other matter in space‚ determine the definitive age of the rings and disprove pre-existing theories about Saturn as a whole. A subject of constant debate for scientists has always been the age of Saturn’s rings. Many say that the rings of Saturn are as old as the Universe itself topping at 4.6 billion years old and others have made the conjecture that the rings are only 100 million years old. By sending the Cassini

would be too scared to be a forensic scientist because I would always be having nightmares from seeing crime scenes and doing the investigation. Now that I am researching careers‚ I am ready to accept that challenge and follow the career that I think is right for me. After thinking long and hard‚ and doing a lot of research I think forensic science is the career path that I should follow. A forensic scientist has many different responsibilities. Forensic scientists must collect data from a crime scene

substances would be able to give off enough Carbon dioxide to inflate a balloon. The scientist will of course be controlling many variables. The scientists independent variable will be the substances they will be using‚ which is dry ice‚ yeast‚ and baking soda with acid. The scientist will also have substances that will remain constant‚ i.e.‚ the balloons‚ the size of the bottles used and the amount of substance the scientist uses. While there have been many different variations

Earth’s Magnetic Field Introduction Earth’s magnetic field is one of the world’s most complicated features. It started to be observed in 1845 by a scientist named Carl Friedman Gauss (Sarfati). The magnetic field is generated inside of the earth’s core and there are many scientists who still debate over how it was first created. There are also many arguments about the many changes that the field has gone through in it’s existence. These arguments are mostly either for a young-earth model or

Screening tests are those that are nonspecific and help a forensic scientist identify several particular drugs that the substance is likely to be. These types of tests are useful when they provide positive and negative results since the forensic scientists can rule out certain types of drugs from the possibilities. 3. What are color tests? Why are these tests used? Color tests involve introducing a chemical

people think that Albert Einstien first discovered black hole in 1916‚ but he only revived a theory about black holes. In 1783‚ a scientist named John Mitchell developed a theory whether if gravity could be so strong that not even light particles could escape. Blackholes can vary in sizes. Some scientists think that blackholes can be as small as an atom. And scientists believe that the smallest

Apel discuss evidence-based practice‚ clinical practice‚ and science. While Kamhi feels that clinical practice cannot be scientific‚ Apel believes the contrary. Though they each note several differences between scientists and clinicians‚ I believe it is possible for clinicians to be scientists. Clinicians may not conduct science in the same regimented way as full-time researchers‚ but they are equally capable of researching practices‚ testing hypotheses‚ collecting data‚ and having their decisions validated

This paper describes the origins of biomolecules hypothesis. Each different hypothesis is derived from a different scientist. It explains their claim and answers the question if the origin of biomolecules using their hypothesis. All the scientists provided evidence to help support their hypothesis. Some of the scientists had experiments to test their hypothesis. They also gave reasoning for supporting their theory. The Primordial Soup Hypothesis was introduced by the Soviet biologist Alexander
